 # Question: How Many Electrons Can N Hold?

## Why are shells named KLMN?

The names of the electron shells come from a fellow named Charles G.

Barkla, a spectroscopist who studied the X-rays that are emitted by atoms when they are hit with high energy electrons.

This innermost shell is now called the K-shell, after the label used for the X-ray..

## Why does M Shell have 8 electrons?

This implies that it can contain a maximum of 2 * electrons. However if you consider the first 18 elements of the periodic table, the maximum number of electrons found in the m-shell is 8. This is because of the fact that electrons are filled in shells in the increasing order of energy.

## How many electrons does n 7 l 3 ml =- 1 have?

l=3, tells you that it is 5f. (0-s, 1-p, 2-d, 3-f). ml=-1 is telling you that it will only take the -1 orbital out of the 7 listed above; therefore, it can only hold 2 electrons.

## How many electrons are in KLMN shells?

32 electronsIn K, L,M, N shells,in the N shell it can accommodate 32 electrons.

## What is the value of KLMN shell?

K denotes the first shell (or energy level), L the second shell, M, the third shell, and so on. In other words, the KLMN(OP) notation only indicates the number of electrons an atom has with each principal quantum number (n). The SPDF notation subdivides each shell into its subshells.

## Which element has 2 5 electrons per shell?

List of elements with electrons per shellZElementNo. of electrons/shell49Indium2, 8, 18, 18, 350Tin2, 8, 18, 18, 451Antimony2, 8, 18, 18, 552Tellurium2, 8, 18, 18, 681 more rows

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

FourteenAnswer and Explanation: Fourteen electrons can be represented by the values n = 4 and l = 3. Quantum number n = 4 is is the fourth energy level, which can be thought of as…

## Why are there 18 electrons in the third shell?

The 3rd subshell consists of an s orbital , a set of (3)p orbitals and a set of (5)d orbitals. Each orbital holds 2 electrons and you will indeed find that you can fir 18 electrons in. … This is because it is the maximum capacity of the 3rd shell and it doesn’t tell about the order in which the electrons are filled.

## How many electrons can n 2 hold?

(a) When n = 2, there are four orbitals (a single 2s orbital, and three orbitals labeled 2p). These four orbitals can contain eight electrons. Again, each orbital holds two electrons, so 50 electrons can fit in this shell.

## How many electrons can n 3 hold?

Orbitals and Electron Capacity of the First Four Principle Energy LevelsPrinciple energy level (n)Type of sublevelMaximum number of electrons (2n2)2p83s18p7 more rows

## What are the 4 sublevels?

sublevels are designated as s, p, d, f, g,…. sublevels, respectively. For known elements no value of l higher than 3 (f sublevel) is necessary. Two quantum numbers (n and l) are required to specify a particular energy sublevel.

## How many electrons can n 4 Hold?

32 electronsHere n is the principal quantum number that describes the energy shell. This means that the fourth energy shell can hold a maximum of 32 electrons.

## How many electrons can n 7 Hold?

You can determine the number of orbitals you have in a particular shell by using the principal quantum number, n . Notice that you can easily find the number of electrons that an atom can accomodate on a particular shell, or energy level, by using the fact that each orbital can hold a maximum of two electrons.

## Why is 3rd shell 8 or 18?

The third shell of an atom has 18 electrons only not 8 electrons. You might be confused because first the electrons of 4s are filled and then the 10 electrons of 3d shells are filled. They are filled because of the n-l rule. … So after filling the 3s and 3p subshell with 8 electrons, the next shell to fill is the 4s one.

## How do electrons behave?

Remember, an electron behaves like a wave as it travels, and an electron wave can easily pass through both slits at the same time, just as a water wave could.) … Each individual electron “knows” about the interference pattern, since the pattern can be built up by electrons passing one at a time through the slits.

## How many electrons can 5d hold?

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.

## What is the 2 8 8 rule in chemistry?

There is a 2-8-8 rule for these elements. The first shell is filled with 2 electrons, the second is filled with 8 electrons, and the third is filled with 8. You can see that sodium (Na) and magnesium (Mg) have a couple of extra electrons. They, like all atoms, want to be happy.

## How many electrons can n 1 Hold?

two electronsThus n=1 shell can hold two electrons. The n=2 (second) shell has: The 2s orbital. The 2p orbitals.
