IONIC AND COVALENT BONDS

neutral atoms

atoms with an equal number of protons and electrons

achieve a stable electron configuration

atoms may lose or gain electrons in order to ________

ion

when an atom loses or gains an electron, it becomes a charged particle called an ___

cation

formed when an atom loses electrons; the atom has more protons than electrons, resulting in a net positive charge; only metals

anions

formed when an atom gains electrons; the atom has more electrons than protons, resulting in a net negative charge; only nonmetals

ionic bonds

____ are formed by the transfer of electrons between atoms; only occur between metals and nonmetals

covalent bond

____ is a type of chemical bond where two atoms share valence electrons; only form between nonmetallic elements; can either be single, double, or triple—-depending on how many pairs

covalent/molecular compounds

molecules formed by covalent bonds are called _____
