After a magnetic field is applied, how many energy levels would you expect for then=3,ℓ=2 state, including electron spin?

The energy level is 5.

Explanation:

Given that,

n = 3

l = 2

We know that,

l shows the number of sub-shells and define the number of angular nodes.

n shows the number of electron shell.

is a quantum number. It is define the number of energy level in a sub-shells .

is define the spin of the electron.

So, The quantum number is

is and for every energy level.

The energy level is 5.

Hence, The energy level is 5.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
