the study of the composition of matter and the changes that matter undergoes.

a mixture composed of two or more elements , at least one of which is a metal.

nonmetal in group 18 of the periodic table that has eight valence electrons (or two in the case of helium) and is unreactive.

electron configuration

the arrangement of all of the electrons of an atom.

negatively charged subatomic particle moving outside the nucleus of all atoms; exhibit properties of both particles and waves.

metal in group 1 of the periodic table that has one valence electron and is highly reactive.

an element that is a poor conductor of heat and electricity.

electrons in the highest occupied principal energy level of an atom (furthest from the nucleus), which are responsible for most of the properties and bonding behavior of atoms and ions; also known as outer-shell electrons.

metal in group 1 of the periodic table that has one valence electron and is highly reactive.

an element that is a poor conductor of heat and electricity.

a diagram in which the valence electrons of an atom are shown as dots distributed around the element’s symbol.

representative element

elements in the s- and p-blocks of the periodic table (groups 1-2 and 13-18); also known as a main-group element.

an element that is found in Groups 3-12 on the periodic table; also known as a transition metal, since all transition elements are metals.

a diagram in which the valence electrons of an atom are shown as dots distributed around the element’s symbol.

delocalized electrons

electrons that are not confined to the bond between two atoms but are, instead, allowed to move freely between three or more atoms.
