What neutral element has the following electron configuration of 1s to the power of 2 and 2s to the power of 2 and 2p to the power of 6 and 3s to the power of2 and 3p to the power of 4

Respuesta :

Given that the element is neutral, and that there are 14 electrons, clearly
Z, the atomic number = 14

Explanation: if Z = 14 , the element is unequivocally indentified. Consult your handy Periodic Table. It was given that there were 14 electrons. Given a neutral atom, there MUST be 14 positively charged particles in the element's nucleus. Thus
Z , the atomic number, MUST be 14.

I'll give you a hint, the element's name starts with an S , hmm, sulfur, selenium, scandium??????
