Vocabulary Words

TermDefinition
Element ELEMENT IS A MATTER THAT IS ONLY MADE OF ONE TYPE OF ATOM.
Element Symbol A chemical symbol is a 1-, 2-, or 3-letter internationally agreed code for a chemical element, usually derived from the name of the element, often in Latin. Only the first letter is capitalised
Element Name Two parts separated by a period using camel case conventions of 80 characters total or less
Atomic Number The number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
Isotope Two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
Average Atomic Mass A dimensionless physical quantity, the ratio of the average mass of atoms of an element to 1/12 of the mass of an atom of carbon-12. The term is equivalent to atomic weight, which is the older term, and which is also sample specific.
