atomicity is the number of atoms in a molecule of a gas.
metalloid is an element that has both metallic and nonmetallic properties, as arsenic, silicon, or boron.
isotopes is members of a family of an element that all have the same number of protons but different numbers of neutrons.
Atoms combine as the electrons from each atom are attracted to the nuclei of the atoms. The results in bonds ranging from 100%covalent to bonds with higher character. The combination of atoms to form compounds occurs when the compounds being formed are at lower energy than the original atoms. In chemical change, the molecules in the reactants interact to form new substances.
