Looking at the periodic table, determine the number of valence electrons present in Potassium (K).
a
3 valence electrons
b
2 valence electrons
c
4 valence electrons
d
1 valence electron
b) 2 valence electrons
To determine the number of valence electrons present in Potassium (K), we need to look at its position on the periodic table.
Potassium is in Group 1 (also known as Group IA or alkali metals) on the periodic table. The group number represents the number of valence electrons an element has.
Since Potassium is in Group 1, it has 1 valence electron.
Therefore, the correct answer is d) 1 valence electron.
