How many electrons are there in the third orbit?

Answer 1

It depends on what you mean by energy level. The common convention is that there are 2 electrons in the first level, 8 in the second, and 8 in the third. Alternatively, this means that there are a total of 18 in the third level, but that convention implies counting the first two levels as well.

The correct answer is 8.

Answer 2

MAXIMUM number of electrons in the 3rd orbit in an atom is 18 electrons

Answer 3

There can be 18 electrons at most in the third orbit. Further explaining, 2 for 3s, 6 for 3p and 10 for 3d.

Answer 4

There are 8 electrons in the third energy level of an atom. This is also known as period three of the Periodic Table, comprising the elements from Sodium through Argon.

Answer 5

18!
