Question

how many electrons are contained in the first, second, and third energy levels, respectively, for the element sulfur, s?

Answer 1

The atomic number of sulfur is 16. The energy levels available are K,L,M for first, second and third energy level respectively. The number of electrons in each level is calculated by the formula : 2n^2, where n is the energy level. Using this formula, there are 2,8 and 6 electrons in the first, second and third energy levels of sulfur respectively.

Answer 2

Answer:

First shell : 2

Second shell : 8

Third shell: 6

Explanation:

The atomic number of sulfur is 16.

The electronic configuration of sulfur is: 1s²2s²2p⁶3s²3p⁴

There are three shells : n =1, n=2 and n=3

The first shell has two electrons, 1s²

The second shell has eight electrons, 2s²2p⁶

The third shell has six electrons, 3s²3p⁴
