## How many electrons are in the 3 energy level?

18 electrons

The first energy level can hold up to 2 electrons, the second energy level can hold up to 8 electrons, the third energy level can hold up to 18 electrons, and the fourth energy level can hold up to 32 electrons. As mentioned above, each energy level or electron shell often contains multiple subshells.

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

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.

**How many electrons can the N 3 principal energy level hold?**

Questions and Answers

Energy Level (Principal Quantum Number) | Shell Letter | Electron Capacity |
---|---|---|

1 | K | 2 |

2 | L | 8 |

3 | M | 18 |

4 | N | 32 |

**Why does the number of electrons in the third shell suddenly change from 8 to 18?**

Look at the periodic table and the Table of Electron Shells handout. Explain why the number of electrons in the third shell suddenly changes from 8 to 18 between the element calcium, Ca, and Gallium, Ga? Because there are 10 euments between Ca and Ga. 8.

### How many orbitals are possible in 3rd energy level?

9

So, the third principal energy level can hold maximum 18 electrons and contain one s-orbital, three p-orbital and five d-orbital. Therefore, the third main energy level contains one s-orbital, three p-orbital and five d-orbital so the total orbitals will be 9.

#### How many orbitals can n 3?

nine orbitals

There are nine orbitals in the n = 3 shell. There is one orbital in the 3s subshell and three orbitals in the 3p subshell.

**How many electron can be placed in the third principal energy level N 3?**

Thus, the third level holds a maximum of 18 electrons: 2 in the s orbital, 6 in the three p orbitals, and 10 in the five d orbitals.

**How many electrons are in the third energy level?**

The third energy level of an atom, referred to as the M shell, can hold a maximum of 18 electrons. The number of electrons that any particular element has in the third level depends on its location on the periodic table and can range from none to 18 electrons.

## How is the maximum number of electrons determined?

The maximum number of electrons on any given level can be determined by the formula two times n squared, where n is equal to the energy level. For the third energy level, the formula is two times three squared. The third energy level contains s, d and p orbitals.

### How many electrons can a subshell of a shell hold?

Each shell contains one or more subshells, each of which also can contain only a maximum number of electrons, determined by the formula 4l + 2, where l is the quantum number of the subshell. The s subshell can contain a maximum of two electrons, the p subshell can hold six electrons,…

#### How many electrons are in the 3s orbital?

The next six elements, in the p-block, also contain two electrons in the 3s orbital and between one and six electrons in the 3p orbital. The next two elements at the beginning of row four also contain two electrons in the 3s orbital and six in the 3p orbital.
