Readers ask: How many electrons can the 2nd energy level hold?

How many electrons can 2s hold?

The 2s subshell holds a maximum of 2 electrons, and the 2p subshell holds a maximum of 6 electrons.

How many electrons are needed to fill the second energy level?

Each energy level can accommodate or “hold” a different number of electrons before additional electrons begin to go into the next level. When the first energy level has 2 electrons, the next electrons go into the second energy level until the second level has 8 electrons.

How many electrons are in the main energy level N 2?

Orbitals and Electron Capacity of the First Four Principle Energy Levels
Principle energy level (n) Type of sublevel Maximum number of electrons (2n2)
2 s 8
p
3 s 18

Why is 3rd shell 8 or 18?

In this sense the third shell can hold 8 electrons. In this sense the third shell can hold a total of 18 electrons. So the third shell can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons.

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

1s 2s 2p 3s 3p represents the electron orbital energy levels.

What is the highest energy level?

What is it meant by the highest occupied energy level in an atom? The highest occupied energy level in an atom is the electron-containing main energy level with the highest number.

How many electrons are in each level?

A. Energy Levels



Each principal energy level can contain up to 2n2 electrons, where n is the number of the level. Thus, the first level can contain up to 2 electrons, 2(12) = 2; the second up to 8 electrons, 2(22) = 8; the third up to 18, 2(32) = 18; and so on.

How many electrons are in each ring?

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.

What is the maximum number of electrons in n 3?

Answer and Explanation:



The maximum number of electrons that can be contained in the n=3 level is 18. This electron shell has enough energy to contain three sublevels: s, p

Which electrons have the most energy?

Electrons at higher energy levels, which are farther from the nucleus, have more energy. They also have more orbitals and greater possible numbers of electrons. Electrons at the outermost energy level of an atom are called valence electrons.

How do electrons behave?

An electron in an atomic orbital state acts somewhat like a plucked guitar string. It is spread out in a three-dimensional cloud-like wavefunction that vibrates. Whereas a guitar string vibrates up and down, an atomic electron wavefunction simply vibrates strong and weak.

What is the maximum number of electrons in n 4 L 3?

Solution: ( c) If n=4 and l=3, it means it is a 4 f-orbital Therefore, the total number od electrons in 4 f-orbital is 14.

Why are outer electrons higher energy?

Using Coulomb’s law, a particle further away from nucleus experiences weaker attraction, hence less energy is needed to maintain orbit⋆ around that e-shell compared to a electron shell closer to nucleus, hence the one closer to nucleus supposedly should have higher energy.
