What is the subshell and number of orbitals: n=3,l=1n=7 and l=2?

Explanation:

Number of orbitals and subshell when n=3 and l=1

Number of orbitals can be calculated by following formula:

n²

n= 3

3² = 9

there 9 orbitals when n =3

Number of subshell:

Azimuthal quantum number (l)

The azimuthal quantum number describe the shape of orbitals. Its value for s, p, d, f... are 0, 1, 2, 3.

l = 1

it means subshell is p.

3px, 3py and 3pz

Number of orbitals and subshell when n=7 and l=2

Number of orbitals can be calculated by following formula:

n²

n= 7

7² = 49

there 49 orbitals when n =7

Number of subshell:

Azimuthal quantum number (l)

The azimuthal quantum number describe the shape of orbitals. Its value for s, p, d, f... are 0, 1, 2, 3.

l = 2

it means subshell is d.

7dz², 7dxy, 7dxz, 7dyz, 7dx²-y²

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²
