O 6
O 8
09
O 16
​

Answer 1

The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus. 06

Answer 2

The atomic number of the atom represent by the model is

8 (answer B)

Step-by-step explanation:

The atomic number of atom is 8 because the model below has a total number of 8 electrons.

that is: 2 electrons in the inner energy level and 6 electrons in the outermost energy level which make a total of 2+6= 8 electrons
