Why is Tennessine in Group 17?

Do you know, how many electrons can be accommodated in the first shell, second shell, third shell, fourth shell, etc…?

Here is the table showing the capacity of orbits to hold electrons. 

Number of electrons in shells.

Orbit / Shell (n)	Maximum no. of electrons this orbit can hold (2 × n2)
K shell, n = 1	2 × 1² = 2
L shell, n = 2	2 × 2² = 8
M shell, n = 3	2 × 3² = 18
N shell, n = 4	2 × 4² = 32
. . .	. . .

Thus, 

• 1st shell can hold 2 electrons.
• 2nd shell can hold 8 electrons.
• 3rd shell can hold 18 electrons.
• 4th shell can hold 32 electrons, and so on…

Now the atomic number of Tennessine (Ts) is 117.

Hence the Tennessine element has electrons arrangement 2, 8, 18, 32, 32, 18, 7.

This electron arrangement indicates that the outermost orbit of tennessine element (Ts) has 7 electrons.

Hence, it lies in group 17.

Why is Tennessine in Period 7?

Let me ask you a question.

How many shells does a tennessine atom have?

It’s 7. Right? 

You have already seen the bohr model of tennessine atom in the above table.

From the Bohr model, it can be found that the number of orbits or shells in tennessine is 7. Hence, as tennessine has 7 orbits, it lies in period 7 of the Periodic table. 

5 facts about Tennessine

Interesting facts about tennessine element are mentioned below.

1. Tennessine was given its name from the “Tennessee”, which is a state in the southeast of the United States.
