Question

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

element name:
Name the element in the third period of the periodic table with two 3p electrons.
element name:

Answer 1

- Krypton.

- Silicon.

Step-by-step 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.
