chemical bond correct answer: the attractive forces that holds two atoms together in a more complex unit ionic bond correct answer: a chemical bond formed through the transfer of one or more electrons from one atom to another atom, metal and nonmetal ionic compound correct answer: a compound in which ionic bonds are present valence electrons are transferred from a metal to a nonmetal, solid at room temperature covalent bond correct answer: sharing of electrons, happens between two nonmetals molecular compound correct answer: a compound in which covalent bonds are present, can be solid, liquid, or gas at room temperature molecule correct answer: basic unit of a compound of covalently bonded atoms valence electrons correct answer: look at the highest value of the electron shell number and the number of valence electrons lewis symbol correct answer: the chemical symbol of an element surrounded by dots equal in number to the number of valence electrons stable correct answer: lowest energy possible localized electron model correct answer: when forming bonds, atoms share electrons through an overlap of atomic orbitals (localized electron- electron stays close to where it started) Octet rule correct answer: atoms tend to share electrons to
