# What Is 1s 2s 2p 3s 3p?

## How many electrons are present in an atom with its 1s 2s 2p 3s 3p subshells filled?

That’s the element that has got a stable electron configuration.

That means that its subshells are completely filled with electrons and its last electrons fill p-subshell..

## What element is 1s2 2s2 2p6 3s2 3p6 4s2 3d6?

ironThus, following the rules on how to fill the orbitals, the electronic configuration of iron (for example) is 1s2 2s2 2p6 3s2 3p6 4s2 3d6 , and it is abbreviated form [Ar] 4s2 3d6.

## How many electrons are needed to fill 3s?

2 electronsSince it follows that: 1 atomic orbital in 3s sublevel x 2 electrons/orbital = 2 electrons can reside in the 3s sublevel. 3 atomic orbitals in 3p sublevel x 2 electrons/orbital = 6 electrons can reside in the 3p sublevel.

## What element has the electron configuration 1s 2s 2p 3s 3p?

Research has shown that unpaired electrons (a single electron in an orbital) are in a lower energy configuration than are paired electrons (two electrons in an orbital)….ElementAtomic numberElectron configurationsulfur161s22s22p63s23p4chlorine171s22s22p63s23p5argon181s22s22p63s23p615 more rows

## What is the next atomic orbital filled in the series 1s 2s 2p 3s 3p?

The order of the electron orbital energy levels, starting from least to greatest, is as follows: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p. Since electrons all have the same charge, they stay as far away as possible because of repulsion.

## Which is higher in energy 2p or 3p?

The energy of some subshells are very close together, such as the 4s and the 3d. When vacant of electrons the 4s is lower in energy and the 3d, but as we fill in electrons the 3d becomes less energetic then the 4s. … Hence, energy of 3p is greater than 2p.

## How many electrons can 5s hold?

## 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.

## What element is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s1?

So, an antimony atom with charge +2 has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p1.
