element Part of the Mathematics glossary: 1) In chemistry and physics, an element is a substance that cannot be broken down into simpler components by any non-nuclear chemical reaction. An element is uniquely determined by the number of protons in the nuclei of its atoms. The number of protons in the nucleus of the atom of an element is known as the atomic number of that element. The number of electrons in the atom of a specific element can vary.

Definition of Element Definition of Element. An element is a substance consisting of atoms which all have the same number of protons - i.e. the same atomic number. Elements are chemically the simplest substances and hence cannot be broken down using chemical methods. Elements can only be changed into other elements using nuclear methods.

- A chemical element or element is a chemical substance consisting of atoms having the same number of protons in their atomic nuclei (i.e. the same atomic number, Z).ccording to IUPAC, chemical elements are not proper nouns in English; consequently, the full name of an element is not routinely capitalized in English, even if derived from a proper noun, as in californium and einsteinium.

What is the scientific definition of an element? A substance composed of atoms having an identical number of protons in each nucleus. Elements cannot be reduced to simpler substances by normal chemical means. A chemical element is a pure chemical substance consisting of one type of atom distinguished by its atomic number, which is the number of protons in its nucleus. 3 people found this useful.

- The definition of an element is one of the substances that constitute all physical matter-wind, air, fire or water, or a natural environment. 1  An example of an element is the fire that cooks the food on a gas range stove. 2  An example of an element is a neighborhood; living in your element.

- An element is a substance made from only one type of atom. For example, Oxygen is an element made up of ONLY oxygen atoms. To understand this better, let us see the how atoms behave. Every element is made up of atoms. Atoms are the smallest piece that can exist in an element.

- Answer: A chemical element, or an element, is a material which cannot be broken down or changed into another substance using chemical means. Elements may be thought of as the basic chemical building blocks of matter. Depending on how much evidence you require to prove a new element has been created, there are 117 or 118 known elements.

- Obsolete definitions. An element is a substance that cannot be decomposed into simpler substances. This was the first useful definition of element, because it allowed elements to be distinguished from other substances experimentally.

- 1 An element is any amount of one particular kind of atom. 2  A compound is a combination of two or more different elements. 3  A mixture is a substance made by combining two or more compounds without each substance chemically bonding.lements are the things you see on the periodic table: an element is a substance made up of only one type of atom. A compound is the result of two or more elements that have b … een chemically bonded. For example, if you chemically bond aluminum and iodine, you get aluminum iodide.

How does an element differ from a compound? An element is a substance that can't be broken down into another substance. Elements are composed of only one type of atom. For example gold is made up of only gold atoms. Com…pounds are substances made up of more than two elements. For example water(H2O) is made up of the elements hydrogen and oxygen.

Review of Elements, Compounds, and Mixtures Any substance that contains only one kind of an atom is known as an element. Because atoms cannot be created or destroyed in a chemical reaction, elements such as phosphorus (P 4) or sulfur (S 8) cannot be broken down into simpler substances by these reactions.

Chemistry A chemical element is a pure substance which is composed of a single type of atom, characterized by its particular number of protons in the nuclei of its atoms, known as the atomic number and represented by the symbol Z. The mass number is the sum of the number of protons and neutrons in a nucleus.hemistry is a branch of physical science that studies the composition, structure, properties and change of matter.

element 1. A substance that cannot be broken down into simpler substances by chemical means. An element is composed of atoms that have the same atomic number; that is, each atom has the same number of protons in its nucleus as all other atoms of that element. Today 112 elements are known, of which 92 are known to occur in nature, while the remaining 20 have only been made with particle accelerators.

Chemical element A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei (i.e. the same atomic number, or Z). There are 118 elements that have been identified, of which the first 94 occur naturally on Earth with the remaining 24 being synthetic elements.

- 1 Each element corresponds to a single entry on the periodic table. An element is a material that consists of a single type of atom. Each atom type contains the same number of protons.  Chemical bonds link elements together to form more complex molecules called compounds.

element 1) In chemistry and physics, an element is a substance that cannot be broken down into simpler components by any non-nuclear chemical reaction. An element is uniquely determined by the number of protons in the nuclei of its atoms. The number of protons in the nucleus of the atom of an element is known as the atomic number of that element. The number of electrons in the atom of a specific element can vary. If the number of electrons is the same as the number of protons, then the atom has no electric charge. However, if the number of electrons is different from the number of protons, the atom is called an ion. If there are more electrons than protons, it is a negative ion; if there are fewer electrons than protons, it is a positive ion. The number of neutrons in the atom of a specific element can also vary.
