Question

How many electrons in an atom can have the n = 5, l = 2 designation? pls answer it i have a test today

Answer 1

Answer:

8 electrons

Pls mark as the brainliest

Answer 2

Explanation:

N gives the energy level on which the electron is located. This is equivalent to the period in which the element is located in the periodic table

N=5 designates

Period=5

Angular momentum quantum number I, tells you the subshell in which the electron resides. The subshell are equivalent to the blocks of periodic table.

You have I=0---the s subshell =the s block

I=1-----the p subshell =the p block

I=2------the d subshell=d block

I=3,----the f subshell =f block

L= 2designates an electron

D block contains a total of 10 groups

10 coloumns of the periodic table.

Each group is equivalent to 1 electron

Therefore, A maximum of 10 electrons can shares the two quantum numbers.

N=5

I=2

These electrons are located in the fifth energy level in the D subshell one of the 5 orbitals

As a note you can find the number of orbitals that can exist In a subshell by dividing the number of groups in a block by 2

Number of orbitals In a subshell =no. Of groups in the block/2

In this case because an orbital can hold a maximum of two electrons as stated by the paulis principle
