What is electron configuration?
It is a notation used to represent how electrons are distributed in different
energy levels
and
orbitals
of an atom.

number
of
electrons
found
in those subshells.

What is the atomic number of an element?
It is the number of
protons
in an atom of that element.
View source
What does the atomic mass refer to?
