# Where Is the G Subshell?

July 27, 2022

The magnetic quantum number (m1) tells us what kind of orbitals the subshell contains. The value ranges from −l to +l. For this case it will be -4 to +4. Therefore, the orbitals contained in the g subshell are {−4,−3,−2,−1,0,+1,+2,+3,+4}=9.

## Where is the G orbital on the periodic table?

The first atom that would need a “g” orbital would be element 121. However, the largest value found so far is 118 (so close!). For comparison: uranium has the element number 92.

## Why is there no G orbital?

They would need more protons than any element we currently know. In short, every known element needs too much energy to keep an electron in an unexcited state in the g or h orbital.

## Is there a sublevel G?

Sublevels are usually denoted by letters. The sublevels l = 0,1,2,3,4,5, … are denoted as s, p, d, f, g, …. Sublevels.

## Are there any G orbitals?

There are nine 5g orbitals for each atom. The higher g orbitals (6g and 7g) are more complex as they have spherical nodes. The shapes of the nine 5g orbitals.

## What is G orbital?

There is no g orbital on the periodic table. The larger the value of l, the more orbitals and electrons there are in it. The direct formula of the number of electrons to be found from ‘l’. The formula is 2× (2l+1) electrons.

## How many electrons are in G subshell?

Each g subshell contains at most 18 electrons.

## Which shell has the first G subshell?

5. Energy shell would be the first with a g subshell.

## Why 5g subshell is not possible?

The reason why there are no 5g atoms in the ground state is due to the instability of large nuclei. Any element with enough protons to balance the charge of 5g of electrons would fall into pieces as nucleons are able to overcome the strong force and exit the nucleus via quantum tunneling.

## Can we have 5g subshell yes or no?

No, your book is right. N=5 contains only 5s, 5p, 5d and 5f. There is (currently) no such thing as 5 g.

## What is G in electron configuration?

G has atomic number 9. So it has an electronic arrangement as 2,7. There are seven electrons in the outer shell, so it has the highest tendency to accept an electron and complete its octet.

## How many g orbitals are allowed in a given shell?

There will be 25 orbitals in the shell where the g subshell will form first.
