A chemical bond formed by atoms sharing electrons, usually nonmetals. | covalent bond |
A compound consisting of covalently bonded nonmetal atoms. | covalent compound |
The measure of how strongly an atom holds its electrons when bonded to other atoms. | electronegativity |
The smallest ratio of elements in an ionic compound that describes its composition; the molecular formula of a covalent compound. | formula unit |
A chemical bond between atoms with very different electronegativities due to the nearly complete transfer of one or more electrons to the anion. | ionic bond |
A compound consisting of ionically bonded metal and nonmetal ions. Molecules are not formed instead ions are arranged in a crystal lattice. | ionic compound |
A way of showing the covalent bonds and arrangement of a molecule using electron dot notation. | Lewis structure |
A chemical bond in which metal atoms are thought to freely share their valence electrons. | metallic bond |
The principle that atoms are generally most stable when they have a full set of electrons in their outer energy level. | octet rule |
