Looking at the periodic table, determine the number of valence electrons present in Phosphorous (P).
a
4 valence electrons
b
2 valence electrons
c
3 valence electrons
d
5 valence electrons
d) 5 valence electrons
To determine the number of valence electrons in Phosphorus (P), you can refer to the periodic table.
First, locate Phosphorus (P) on the periodic table. Phosphorus is in the fifteenth group, also known as Group 15 or Group VA.
Group number indicates the number of valence electrons in the elements of that group. Since Phosphorus is in Group 15, it has 5 valence electrons.
Therefore, the correct answer is d) 5 valence electrons.
