 # What Element Has 3 Electrons In The 2p Sublevel?

## How many electrons can 3p hold?

six electronsThe 2p, 3p, 4p, etc., can each hold six electrons because they each have three orbitals, that can hold two electrons each (3*2=6).

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).

First, we look at the n=1 shell (the first shell)..

## How many electrons are in each shell?

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 values of L are possible for n 3?

Because n=3, the possible values of l = 0, 1, 2, which indicates the shapes of each subshell.

## How many 2p electrons are in neon?

six electronsNeon is the tenth element with a total of 10 electrons. In writing the electron configuration for neon the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Ne go in the 2s orbital. The remaining six electrons will go in the 2p orbital.

## Which element has 3 electrons in the n 4 energy level?

Lithium has 3 electrons; 2 of the 3 electrons occupy the s sublevel in principal energy level 1. The 3rd electron must go in the next available sublevel, 2s.

## How many orbitals are there in n 3?

nine orbitalsThere are nine orbitals in the n = 3 shell. There is one orbital in the 3s subshell and three orbitals in the 3p subshell. The n = 3 shell, however, also includes 3d orbitals. The five different orientations of orbitals in the 3d subshell are shown in the figure below.

## What is the only metalloid in Period 3?

SiliconOne metalloid of period 3 is Silicon.

## How many electrons are in a 2p sublevel?

6 electronsThere can be two electrons in one orbital maximum. 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.

## What element has a 4s sublevel with 2 electrons?

calciumEven though the 4s sublevel is filled, the last electron went into that sublevel, making it a member of the s-block. It has 2 valence electrons. The element is calcium, a metal.

## Are zn2+ and Ni Isoelectronic?

So, sure, they’re isoelectronic, but not because of having the same electronic structure; instead, it’s purely due to how many electrons they have, not where they are. … They have the same number of valence electrons, but they aren’t identical compounds.

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

Physicists and chemists use a standard notation to indicate the electron configurations of atoms and molecules. For atoms, the notation consists of a sequence of atomic subshell labels (e.g. for phosphorus the sequence 1s, 2s, 2p, 3s, 3p) with the number of electrons assigned to each subshell placed as a superscript.

## Does the 3p sublevel have 3 electrons?

phosphorus has three electrons in its 3p sub level. neon has its highest energy level completely filled.

## Why is 3d higher energy than 4s?

We say that the 4s orbitals have a lower energy than the 3d, and so the 4s orbitals are filled first. … The electrons lost first will come from the highest energy level, furthest from the influence of the nucleus. So the 4s orbital must have a higher energy than the 3d orbitals.

## How many p orbitals are there in N 1?

There are n2 orbitals for each energy level. For n = 1, there is 12 or one orbital. For n = 2, there are 22 or four orbitals. For n = 3 there are nine orbitals, for n = 4 there are 16 orbitals, for n = 5 there are 52 = 25 orbitals, and so on.

## Which atom has three 2p electrons in its ground state?

nitrogenSimilarly, for nitrogen in its ground state, Hund’s rule requires that the three 2p electrons singly occupy each of the three 2p orbitals. This is the only way that all three electrons can have the same spin.
