1. Locate the element on the periodic table.
2. Find the element’s atomic number (which is the same as the
number of protons)
3. Find the element’s atomic weight.
4. Round off the atomic weight to the nearest whole number to find
the atomic mass.
5. Subtract the atomic number from the atomic mass (The numbers
after the decimal point represent the usually very small mass of
the electrons in the atom.)

Asked in Chemistry
How is the atomic number of an atom determined?
The atomic number of an element is determined by the number of
protons in its nucleus. It's that simple. Note that the number of
electrons will only equal the number of protons in an atom that is
neutral, and can vary. The number of neutrons can vary as well, and
we use the term isotope to differentiate between atoms of a given
element with different numbers of neutrons in their nucleus.

Nucleus of a atom?
The nucleus of an atom is an atom's dense, positively-charged,
spherical center, made up of protons (positively charged atomic
particles) and neutrons (neutrally charged atomic particles). The
number of protons in an atom determines what element the atom is
(determined by atomic number). The number of protons plus the
number of neutrons in an atom determines the atom's mass.
