The  atomic  number of the atom represent by the model is

8 (answer B)

 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

Answer: The the atomic number of this atom is 8.

Explanation: The particles with zero charge represents neutrons, The particles with negative charge represents electrons and the particles with positive charge represents protons.

The number of particles with negative charge are eight in number, thus there are eight electrons. The number of particles with positive charge are eight in number, thus there are eight protons. Thus it is a neutral atom.

The number of electrons represent the atomic number for a neutral atom. Thus the element has atomic number of 8.
