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:

- 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:

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

Best regards.
