Antimony Valence Electrons

Antimony Valence Electrons
Antimony valence electrons

Antimony has 5 valence electrons.


We can write the valence electrons of antimony using two different methods:

#1 Using periodic table
#2 Using electron configuration

Let’s break down each method in detail.

#1 Using Periodic Table

Periodic table

Get the periodic table having the chemical elements marked on it as mentioned above.

Now mark the location of antimony on the periodic table.

Next, mark the group number of antimony on the periodic table.

The valence electrons of each main group element can be determined by the column in which it is located.

(i.e., all group 1 elements have 1 valence electron, all group 2 elements have 2 valence electrons, skip the transition metals… then, all group 13 elements have 3 valence electrons, all group 14 elements have 4 valence electrons, and so on up to group 18 elements)

Since antimony is in group 15, it has 5 valence electrons.

#2 Using Electron Configuration

  • First, write electron configuration of antimony

The electron configuration of antimony is [Kr] 5s2 4d10 5p3.

Learn how to find: Antimony Electron Configuration

  • Second, find highest energy level in electron configuration
Green colored number represent highest energy level

In the above electron configuration, the highest energy level (5) is marked with green color.

  • Finally, count electrons of that energy level
Number circled with green color represent electrons

The 5th energy level contains 5s and 5p subshells. There are 2 electrons in the 5s subshell and 3 electrons in the 5p subshell. So antimony has a total of 2 + 3 = 5 valence electrons.
