| ionic compound | brittle and have high melting point, some highly soluble |
| chemical bond | force of attraction that holds atoms or ions together |
| corrosive substances | cause damage to eyes, skin, or respiratory and gastrointestinal tracts |
| valence electrons | electrons in the outermost energy level of an atom |
| the combining of atoms to form molecules or compounds | chemical bond |
| a compound made of oppositely charged ions | ionic compound |
| ionic bond | an attraction between oppositely charged ions |
| high | melting point of ionic compounds |
| crystal lattice | a three-dimensional pattern |
| determines if a compound is covalent or ionic | valance |
| formwhen metals react w/nonmetals | ionic compounds |
| highly soluble | dissolve easily in water |
| can conduct electric current | the solution that forms when ionic compounds dissolves |
| covalent compound | a chemical compound formed by the sharing of electrons |
| molecule | the smallest unit of a substance that keeps all of the physical and chemical properties of that substance |
| properties of covalent compounds | low melting point, don't dissolve easily in water, and don't conduct electric current |
