# How many electrons can the 3rd energy level hold at maximum?

## How many electrons can the 3rd energy level hold at maximum?

18 electrons
The third shell in its lowest state has room for 8 electrons but including the higher energy 3d electrons it has a capacity of 18 electrons.

How many electrons are there in the third shell of the atom with atomic number 23?

There are 13 electrons present in the third shell (principal energy level) of the atom with atomic number 23.

What is the maximum number of electrons possible in the shell with n 3 in an atom?

# of e– = 18 Thus, the maximum number of electrons possible when n = 3 is 18.

### How many electrons can 3rd Shell hold?

eight electrons
The second shell can hold a maximum of eight electrons. When this is filled, electrons go into the third shell, which also holds a maximum of eight electrons….Electron shells.

Energy shell Maximum number of electrons
First 2
Second 8
Third 8

Does the third shell hold 8 or 18 electrons?

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. For an explanation of why electrons exist in these shells see electron configuration.

How many electrons are in the third shell?

The second shell can hold a maximum of eight electrons. When this is filled, electrons go into the third shell, which also holds a maximum of eight electrons….Electron shells.

## How many electrons are there in the third shell of the atom with atomic number 20?

8 electrons
M-shell is the third energy level and can have a maximum of 8 electrons. The atomic number of an element is 20.

How many electrons can the 3rd Shell hold?

8
The second shell can hold a maximum of eight electrons. When this is filled, electrons go into the third shell, which also holds a maximum of eight electrons….Electron shells.

Energy shell Maximum number of electrons
Third 8

Why is 3rd shell 8 or 18?

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….List of elements with electrons per shell.

Z 3 Lithium 2, 1 1

### Why does the third shell of electrons only hold a maximum of 18 electrons?

Each orbital carries 2 electrons and you can actually find that 18 electrons can be shot in. This is because it is the 3rd shell’s full power and it does not say the order in which the electrons are filled. The general formula is that the nth shell can hold up to 2(n2) electrons in principle.

How many electrons can 3rd shell hold?

How many electrons can the 4rd shell hold?

BRIAN M. The fourth energy level has 18 electrons. The fourth energy level of the periodic table includes the 4s 3d and 4p orbitals.

## What is the maximum number of electrons that can occupy a shell?

The closest shell has a value of n=1. The next shell has a value of n=2, etc. The maximum number of electrons possible in the first four energy levels are: Using the above you can work out the maximum number of electrons that can occupy a shell is 2n 2.

How many electrons are in third shell? Energy shell Maximum number of electrons First 2 Second 8 Third 8

What is the total number of electrons in a subshell?

Subshell: Total Number of Electrons in Shell: 1st Shell: 1s: 2: 2nd Shell: 2s, 2p: 2 + 6 = 8: 3rd Shell: 3s, 3p, 3d: 2 + 6 + 10 = 18: 4th Shell: 4s, 4p, 4d, 4f: 2 + 6 + 10 + 14 = 32

How many electrons are in the K shell?

For instance, K shell is the first shell and it can hold up to 2 (1) 2 = 2 electrons. Similarly, L shell is the second shell and it can hold up to 2 (2) 2 = 8 electrons. How many electrons are in the 5 shell? What is the maximum number of electrons in n 4 L 3?
