Chemistry : Atoms, Molecules, Elements and compounds A compound is formed when atoms or molecules of different elements combine. In a compound, elements are chemically combined in a fixed proportion. Examples: 1  Hydrogen and oxygen are combined in a fixed proportion of 2:1 to form the compound water [H 2 O]. Since atoms are electrically neutral, the number of protons equal the number of electrons in an atom. 2  Atomic weight (or relative atomic mass) of an element is the number of times an atom of that element is heavier than an atom of hydrogen. 3  The atomic weight of hydrogen is taken to be unity [1].

What's the difference between atom, element, molecule and compound? An atom is the smallest particle in anything and everything.An element only has one type of atom and is found in a periodic table. A molecules is two atoms joined together. A compound is two or more elements chemically joined.Both elements and compounds have molecules. Hope this helps.eport Abuse. an atom is the smallest undevidable substance of matter. an element is a substance made by two similar atome by a covalent bond. a molecule is a group of atoms; different ,made by a covalent bond. a compound is a substance made by ionic bond.

Essential Question 2-1 How are elements and compounds related? A molecule is formed when two or more atoms join together chemically. A compound is a molecule that contains at least two different elements.ater (H 2 O), carbon dioxide (CO 2) and methane (CH 4) are compounds because each is made from more than one element. The smallest bit of each of these substances would be referred to as a molecule.

Molecule A scanning tunneling microscopy image of pentacene molecules, which consist of linear chains of five carbon rings. AFM image of 1,5,9-trioxo-13-azatriangulene and its chemical structure. A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge. However, in quantum physics, organic chemistry, and biochemistry, the term molecule is often used less strictly, also being applied to polyatomic ions.

Difference between Molecules and Compounds This happens via a chemical reaction. A molecule is the smallest amount of a chemical substance that can exist. Essentially, a compound is a type of molecule. A molecule can be made up of two or more atoms of the same element or two or more atoms of different elements. However, compounds are molecules that are made up of atoms of different molecule. Atoms are the basic units that all matter is made of. Atoms are tiny, ranging from 0.1 to 0.5 nanometers in width.

MOLECULES They can even be made up of just one atom. The element argon is a one-atom molecule. Other molecules can consist of two atoms of the same element. The oxygen molecule is made up of two oxygen atoms bonded together.However, in certain circumstances, three oxygen atoms bond together, forming a molecule called ozone.IND OUT MORE. Most atoms join up with other atoms through chemical BONDS to form larger particles called molecules. They can join up with atoms of the same element or with atoms of different elements. Substances whose molecules contain different types of atom are called compounds.

atom atom - (physics and chemistry) the smallest component of an element having the chemical properties of the element. substance - the real physical matter of which a person or thing consists; DNA is the substance of our genes.

Molecule If it contains only one type of atom it is called an element. An exception to this is diatomic gases (for example: Oxygen, O 2, where the molecule contains two atoms of the same element, bonded covalently.

What is the difference between molecules and compounds? A molecule is formed when two or more atoms of an element chemically join together. If the types of atoms are different from each other, a compound is formed. Not all molecules are compounds, since some molecules, such as hydrogen gas or ozone, consist only of one element or type of atom. molecule is formed when two or more atoms of an element chemically join together.

Not all molecules are compounds, since some molecules, such as hydrogen gas or ozone, consist only of one element or type of atom.

Molecules Compounds. When atoms of different types of elements join together, they make molecules called compounds. Water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. This is why it's called H 2 O. Water will always have 2 times the number of hydrogen atoms as oxygen atoms.his is because they are all made up of different types of molecules. Molecules are not only made up of different types of atoms but also different ratios. Like in the water example above, a water molecule has 2 hydrogen atoms and 1 oxygen atom.

CHEMISTRY I: ATOMS AND MOLECULES Cell Compounds. [Background Chemistry] Elements are defined as substances that consist of one type of atom, for example Carbon atoms make up diamond, and also graphite. Pure (24K) gold is composed of only one type of atom. Atoms are the smallest particle into which an element can be divided.

Difference Between Molecules and Compounds A compound is a substance that is made up of two or more elements having chemical bond between each other in a permanent percentage by mass. A molecule is the smallest part of a compound. One or more atoms that are chemically unite to form a molecule.

Contents: Compound vs Element For example, 1 atom of sodium (Na) combines with 1 atom of chlorine (Cl) to form one molecule of sodium chloride (NaCl) compound. The elements in a compound do not always retain their original properties and cannot be separated by physical means.

Chemistry So, in summary: 1  element - a basic substance that can't be simplified (hydrogen, oxygen, gold, etc...) 2  atom - the smallest amount of an element. 3  molecule - two or more atoms that are chemically joined together (H2, O2, H2O, etc...) 4  compound - a molecule that contains more than one element (H2O, C6H12O6, etc...)

Contents: Compound vs Element Elements and compounds are pure chemical substances found in nature. The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions.Examples of elements include iron, copper, hydrogen and oxygen. compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Distinguishing Feature. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds.

Difference between atoms, molecules, elements,compounds and mixtures Note that a compound: 1  consists of atoms of two or more different elements bound together, 2  can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means), 3  has properties that are different from its component elements, and.  always contains the same ratio of its component atoms.

A molecule made up of two or more different elements is called a what? If a molecule is made up of two ore more different elements it is called a compound, it is also a substance. If all the molecules were the same it would be an element. 1 person found this useful. Edit.

What is the difference between a compound and a molecule? A molecule is formed when two or more atoms join together chemically. A compound is a molecule that contains at least two different elements.he smallest bit of each of these substances would be referred to as a molecule. For example, a single molecule of molecular hydrogen is made from two atoms of hydrogen while a single molecule of water is made from two atoms of hydrogen and one atom of oxygen.

Understanding the Relationships between Elements, Molecules & Compounds Certain molecules are also compounds. A compound is a group of two or more different atoms chemically bonded together. What makes compounds special is that there are at least two different elements, or types of atoms in the group.All compounds are molecules, but not all molecules are compounds.ompounds Are Different Elements. Molecules are groups of two or more atoms, but there is a special sub-group of molecules, too. These are compounds, and a compound is a group of two or more different atoms chemically bonded together. The key here is that compounds are made of at least two different elements.

What Is the Difference Between an Atom and a Molecule? Most molecules are formed when atoms bond in a particular way. For instance, the chemical formula for water is H20, meaning that two hydrogen atoms bond with one oxygen atom. One set of this compound, exactly two hydrogen atoms and one oxygen atom, makes a molecule.
