Question

Name the element in the fourth period of the periodic table with six 4p electrons.

Answer 1

Answer:

- Krypton.

- Silicon.

Explanation:

Hello.

In this case, since the first element's last term in the electron configuration is 4p⁶, by looking at the fourth period, the only element having sic 4p electrons is Kr as its electron configuration is:

$Kr^{36}:1s^2,2s^2,2p^6,3s^2,3p^6,4s^2,3d^1^0,4p^6$

In the second case, the element of the third period having two 3p electrons or $3p^2$ the last term in its electron configuration is silicon as shown below:

$Si^{14}:1s^2,2s^2,2p^6,3s^2,3p^2$

Best regards.
