## How many electrons can a sub level hold?

The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max. And the 4 sublevel has 7 orbitals, so can contain 14 electrons max.

### How many electrons can 3d Fit?

The 3d, 4d etc., can each hold ten electrons, because they each have five orbitals, and each orbital can hold two electrons (5*2=10).

What is meant by 3p 3?

#33 what is meant by 3p3? 3rd orbital in p sublevel 3 electrons.

Why is 3rd shell 8 or 18?

Each shell can contain only a fixed number of electrons, up to two electrons can hold the first shell, up to eight (2 + 6) electrons can hold the second shell, up to 18 (2 + 6 + 10) can hold the third shell and so on. …

## How many electrons are in the 4th Shell?

18 electrons
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 highest energy level?

Electrons that are in the highest energy level are called valence electrons. Within each energy level is a volume of space where specific electrons are likely to be located.

Which electron has the highest energy?

Valence electrons
Valence electrons are the highest energy electrons in an atom and are therefore the most reactive.

What is 1s 2s 2p 3s 3p?

In the question 1s 2s 2p 3s 3p represents electron orbital energy levels. The sequence of orbital energy levels is as always-1s < 2s = 2p < 3s = 3p = 3d <4s = 4p = 4d= 4f. The orbital having the same energy is called a degenerate orbital.

## What does 1s 2s 2p mean?

The superscript is the number of electrons in the level. The number in front of the energy level indicates relative energy. For example, 1s is lower energy than 2s, which in turn is lower energy than 2p. The number in front of the energy level also indicates its distance from the nucleus.

### Is it 8 or 18 electrons in third shell?

In this sense the third shell can hold 8 electrons. 4s2 not the third shell, but the next 10 electrons go into the 3d orbitals that are part of the third shell but shown on the fourth shell level. So the third shell can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons.

Why are there 18 electrons in the third shell?

A s orbital, a set of (3)p orbitals and a set of (5)d orbitals form the 3rd subshell. 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.

What are the sublevels and electrons in Level 3?

Level 3 has 3 sublevels – s, p, and d. Level 4 has 4 sublevels – s, p, d, and f. These are pictured below. The sublevels contain orbitals. Orbitals are spaces that have a high probability of containing an electron. In other words, an orbital is an area where the electrons live.

## How many orbitals does the s sublevel have?

The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max. And the 4 sublevel has 7 orbitals, so can contain 14 electrons max.

### How many electrons can be in the n = 1 level?

Since electrons cannot have the same set of quantum numbers, a maximum of two can be in the n = 1 level, and a third electron must reside in the higher-energy n = 2 level. If there are two electrons in the n = 1 level, their spins must be in opposite directions.

Which is the maximum number of electrons in a subshell?

Thus the maximum number of electrons that can be in a subshell is 2 (2l + 1). For example, the 2 s subshell in Example 1 has a maximum of 2 electrons in it, since 2 (2 l + 1) = 2 (0 + 1) = 2 for this subshell. Similarly, the 2 p subshell has a maximum of 6 electrons, since 2 (2 l + 1) = 2 (2 + 1) = 6.
