a. number 16 on the periodic table ... the number of protons in the nucleus
b. the atomic mass is neutrons and protons ... (32 - 16) means 16 neutrons
c. valence electrons is determined by the periodic table
An atom has an atomic mass of 32.06 and an atomic number of 16.
a. Determine the identity of the atom.
b. Determine the number of neutrons in the most common form of the atom.
c. Determine the number of valence electrons this atom has.

You should know that you can look on a periodic table and answer this.
Atomic number is the number of protons in the nucleus. That number is on the periodic table.
You can find the
You can find the # neutrons from
mass number = 32 = # protons + # neutrons. You have mass number and protns, solve for neutrons.
The electron configuration is 2 in first shell, 8 in second shell. So how many in the third shell. Post your work if you get stuck.
