Please help! Will mark brainliest and 5 stars. ONLY RIGHT ANSWERS. Using the periodic table, match the number of valence electrons with the group number.

Question 1 options:

1 valence electron

4 valence electrons

8 valence electrons

We don't know

3 valence electrons

Group 1

Group 14

Group 18

Group 3

Group 13

1 valence electron - group 1

4 valence electrons - group 14

8 valence electrons - group 18

3 valence electrons - group 13

Explanation:

Elements are placed in the periodic table according to the number of valence electrons in their outermost shell.

Hence,  all elements in the same group have the same number of outermost shell electrons.

Group 1 elements have only one valence electron, group 14 elements have 4 valence electrons, group 13 elements have 3 valence electrons while group 18 elements have 8 valence electrons.
