Molecule The molecular weight of a molecule is the sum of the atomic weights of its component atoms. If a substance has molecular weight M, then M grams of the substance is termed one mole. The number of molecules in one mole is the same for all substances; this number is known as Avogadro’s number (6.022140857 × 1023).

Pseudohalogen  [show article only]hover over links in text for more info In the kinetic theory of gases, the term molecule is often used for any gaseous particle regardless of its composition. According to this definition, noble gas atoms are considered molecules despite being composed of a single non-bonded atom.toms and complexes connected by non-covalent bonds such as hydrogen bonds or ionic bonds are generally not considered single molecules. Molecules as components of matter are common in organic substances (and therefore biochemistry). They also make up most of the oceans and atmosphere.

Molecular geometry Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It influences several properties of a substance including its reactivity, polarity, phase of matter, color, magnetism and biological activity. The angles between bonds that an atom forms depend only weakly on the rest of molecule, i.e. they can be understood as approximately local and hence transferable properties.

What is a molecule? A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of atom s that are held together by chemical bonds.he atoms of some elements do not easily bond with other atoms. Examples are neon and argon. Molecules can vary greatly in size and complexity. The element helium is a one-atom molecule. Some molecules consist of two atoms of the same element.

- An organic molecule is a molecule that is created—or theoretically could be created—by a living organism. Sugar, DNA and fat are all organic molecules. Quartz, graphite and plastic are not organic molecules. Most organic molecules have a carbon backbone, meaning that their structure is made up of carbon atoms bonded to other carbon atoms. There are still other atoms in the molecule, but without the structural support provided by carbon, the entire molecule would all fall apart.

- A molecule is formed when atoms join together by chemical bonds. There are over a hundred different types of atom, called elements. The atoms of a particular element are identical to each other.

Definition of Diatomic Diatomic molecules are molecules made of two atoms chemically bonded together. The atoms can be of the same element (homonuclear molecules), or of different elements (heteronuclear molecules). Familiar examples of diatomic molecules of elements are the five gaseous state diatomic elements: Cl 2, F 2 H 2, N 2 ,and O 2.n homonuclear diatomic molecules, the bonding is covalent. Each atom in the molecule has equal electronegativity; electrons are shared equally between the two atoms. In heteronuclear diatomic molecules, the atoms differ in electronegativity; these molecules have polar covalent bonds. The molecule forms a dipole.

- In this case there are three groups of electrons around the central atom and the molecualr geometry of the molecule is defined accordingly. The term electron-pair geometry is the name of the geometry of the electron-pair/groups/domains on the central atom, whether they are bonding or non-bonding. Molecular geometry is the name of the geometry used to describe the shape of a molecule. The electron-pair geometry provides a guide to the bond angles of between a terminal-central-terminal atom in a compound. The molecular geometry is the shape of the molecule. So when asked to describe the shape of a molecule we must respond with a molecular geometry. If asked for the electron-pair geometry on the central atom we must respond with the electron-pair geometry.

- A molecule is the smallest  particle of a chemical compound. Molecules are formed by atoms in a  multitude of different arrangements.   - Most atmospheric oxygen forms diatomic molecules (O2),  but also ozone (O3)   - One molecule of water has one atom of hydrogen and two atoms of  oxygen.n atom consists of a nucleus (containing one or more protons and  zero or more neutrons) and some number of electrons. Atoms have the  same number of protons and electrons, … because otherwise, you would  have an ion.   A molecule consists of two or more atoms bonded together.

Questions and Answers A molecule is what you get when any atoms join together. A compound is what you get when atoms of two or more different elements join together. All compounds are molecules, but not all molecules are compounds. Water is a molecule because it is made from atoms that have been chemically combined. It is also a compound because the atoms that make water are not all the same - some are oxygen and some are hydrogen. Oxygen in the atmosphere is a molecule because it is made from two atoms of oxygen. It is not a compound because it is made from atoms of only one element - oxygen. This type of molecule is called a diatomic molecule, a molecule made from two atoms of the same type.
