Tin Valence Electrons

Tin has 4 valence electrons.

Methods

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

#1 Using periodic table
#2 Using electron configuration

Let’s break down each method in detail.

#1 Using Periodic Table

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

Now mark the location of tin on the periodic table.

Next, mark the group number of tin 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 tin is in group 14, it has 4 valence electrons.

#2 Using Electron Configuration

• First, write electron configuration of tin

The electron configuration of tin is [Kr] 5s² 4d¹⁰ 5p².

Learn how to find: Tin Electron Configuration

• Second, find highest energy level in electron configuration

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

• Finally, count electrons of that energy level

The 5^th energy level contains 5s and 5p subshells. There are 2 electrons in the 5s subshell and 2 electrons in the 5p subshell. So tin has a total of 2 + 2 = 4 valence electrons.
