Determine the atomic number of a neutral atom with 3 shells and 6 electrons in its valence shell
What will be an ideal response?
The innermost shell of the atom holds 2 electrons. The next shell holds a maximum of 8 electrons. The valence shell of this particular atom holds 6 electrons. This atom has 3 shells and 16 total electrons. Add the electrons (2 + 8 + 6 = 16). In a neutral atom, the numbers of protons equals the number of electrons. Thus, this atom has an atomic number of 16.
