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

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

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.
