Atomic Mass Unit​

Answer 1

molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.

Answer 2

Answer:

1. An ion formed by the removal from (positive ions) or addition to (negative. ions) a molecule of one or more electrons without fragmentation of the. molecular structure.
2. Formula unit mass of a substance is the sum of the atomic masses of all the atoms present in the formula of a respective compound
3. an uncharged molecule (typically highly reactive and short-lived) having an unpaired valency electron.
4. the number of protons in the nucleus of an atom, which is characteristic of a chemical element and determines its place in the periodic table.
5. The mass number is defined as the total number of protons and neutrons in an atom. The number of neutrons = mass number − atomic number.
6. a unit of mass used to express atomic and molecular weights, equal to one twelfth of the mass of an atom of carbon-12.
