Polonium Valence Electrons

Polonium Valence Electrons
Polonium valence electrons

Polonium has 6 valence electrons.

Methods

We can write the valence electrons of polonium 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 polonium on the periodic table.

Next, mark the group number of polonium 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 polonium is in group 16, it has 6 valence electrons.

#2 Using Electron Configuration

  • First, write electron configuration of polonium

The electron configuration of polonium is [Xe] 6s2 4f14 5d10 6p4.

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

In the above electron configuration, the highest energy level (6) is marked with green color.

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

The 6th energy level contains 6s and 6p subshells. There are 2 electrons in the 6s subshell and 4 electrons in the 6p subshell. So polonium has a total of 2 + 4 = 6 valence electrons.
