Question

describe the presence of subshells in a shell ? please important​

Answer 1

Answer:

Explanation:

Electrons orbit the nucleus of an atom at different ranges, called shells. Each shell has a different energy level, increasing the further it is from the nucleus. Each energy level is given a number called the principal quantum number, n. ... The n number determines how many of the subshells make up the shell.

Answer 2

Explanation:

Shell

An electron shell is an orbit which is followed by the electrons around an atom's nucleus.

Subshell

A subshell is the set of states which are defined by the azimuthal quantum number (l), within a shell.

The values are as follows.

• l = 0 corresponds to s subshell.
• l = 1 corresponds to p subshell.
• l = 2 corresponds to d subshell.
• l = 3 correspond to f subshell.

The maximum number of electrons which can occupy a subshell is given by the formula

2(2l + 1).
