What is the element with a valence electron configuration of 4s2 4p3?

Answer 1

Krypton. In order to find this you have to look at the periodic table. Imagine the Periodic Table is divided into three sections, the first two columns, 1A and 2A, the middle section, the transition metals, and the right side, 3A to 7A.

The first two columns are the s electrons, the middle section is the d electrons, and the right side is the p electrons (oversimplification).

4s2 4p6 means go to the 4th period (row). two s's and 6 p's. Just count it. the 4th element in the p electrons in the 4th period is Krypton.
