Question

question 15 (multiple choice worth 5 points) (03.01r mc) the diagram shows the electron configuration of an atom of an element for the electrons in the s and p orbitals. what is the group number of the element in the periodic table?

Explanation:

Step1: Count valence electrons

The out - most shell electrons are valence electrons. Counting the electrons in the outermost shell of the electron - configuration diagram, we see 4 electrons.

Step2: Determine group number

In the periodic table, for main - group elements, the number of valence electrons in s and p orbitals is equal to the group number (for groups 1 - 2 (s - block) and 13 - 18 (p - block)). Since there are 4 valence electrons, the group number is 14.

Answer:

14
