Atomic Structure and Interatomic Bonding Quiz

The atomic number is equal to the number of protons in the nucleus of an atom, which is also equal to the number of electrons in a neutral species.

Atomic mass unit (amu) is defined as 1/12th of the mass of a 12C atom. The atomic weight is the weight of 6.022 x 10^23 molecules or atoms, and 1 amu per atom is equivalent to 1 g/mol.

Chemical, electrical, thermal, and optical properties are determined by electronic structure.
