# What is the maximum number of electrons per shell?

## What is the maximum number of electrons per shell?

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.

### How many electrons are in the 7th shell?

Therefore, the total number of orbitals present in the seventh shell is 49. Note: The maximum electron an orbital can hold is two and both the electron should have the opposite. In the seventh shell 49 orbitals are present so total electrons present in 49 orbital is 98.

**Can 4dxy hold 2 electrons?**

Each orbital can hold two electrons. One spin-up and one spin-down. This means that the 1s, 2s, 3s, 4s, etc., can each hold two electrons because they each have only one orbital. The 2p, 3p, 4p, etc., can each hold six electrons because they each have three orbitals, that can hold two electrons each (3*2=6).

#### Why does Period 3 contain only 8 elements?

According to the 2n2 rule, the maximum number of electrons in the third period = 2 x (3)2 = 18. But, the last shell cannot accommodate more than 8 electrons so, the number of electrons in third period is 8. Hence, the number of elements is also 8.

**What is the max number of electrons in a 4P subshell?**

A 4p orbital, which is part of the p subshell located on the fourth energy level, can hold a maximum of two electrons. In fact, any orbital, regardless of its energy level, subshell, and orientation, can hold a maximum of two electrons, one having spin-up and one having spin-down.

**What is the maximum number for electrons a the fourth level?**

The fourth energy level doesn’t necessarily equate to the fourth period in the periodic table. The maximum number of electrons to be gained in the fourth period is 18, because we have: 2 electrons from the 4s orbital series; 10 electrons from 3d orbital series; and

## How many electrons are held in the first energy level?

The first energy level can contain 2(1) 2 or two electrons; the second can contain up to 2(2) 2 or eight electrons; the third can contain up to 2(3) 2 or 18 electrons, and so on.

**What is the maximum number of electrons in a 5d orbital?**

As a d subshell has five orbitals and each orbital can hold a maximum of two electrons, therefore the maximum number of electrons that would be present in the 5d orbital would be 10.
