5. 1 H Atomic number Atomic symbol Atomic weight
Atomic weight
Atomic number is the number of protons in the nucleus of an atom.
Atomic weight is the average atomic mass for the naturally
occurring element, expressed in atomic mass units.

7. Metals, Nonmetals and Metalloids
A metal is a substance or mixture that has a characteristic
luster or shine and is a good conductor of heat and electricity.
A nonmetal is an element that does not exhibit the characteristics
of a metal.
A metalloid, or semimetal, is an element having both metallic and
nonmetallic properties.
