Question

Distinguish
between shell and subshell​

Answer 1

Answer:

${\huge{\sf{\green{\underline {\underline {Answer }}}}}}$

In an atom, a shell is a collection of subshells with the same principle quantum number, n . ... Orbitals each hold two electrons, and electrons in an orbital with the same principle quantum number, angular momentum quantum number, and magnetic quantum number, ml are part of the same orbital...

Electron shells consist of one or more subshells, and subshells consist of one or more atomic orbitals. Electrons in the same subshell have the same energy, while electrons in different shells or subshells have different energies.....

please mark as brainliest.......

Answer 2

|| ✰✰ ANSWER ✰✰ ||

Shells are a collection of subshells with the same principle quantum number, and subshells are a collection of orbitals with the same principle quantum number and angular momentum quantum number.

||✪✰ EXPLANATION ✰✪||

Shells

• The maximum number of electrons that can be accommodated in a shell is based on the principal quantum number (n). It is represented by the formula 2n2, where ‘n’ is the shell number.

Subshells

• The subshells into which electrons are distributed are based on the azimithual quantum number (denoted by ‘l’).
• This quantum number is dependent on the value of the principal quantum number, n. Therefore, when n has a value of 4, four different subshells are possible.
• When n=4. The subshells correspond to l=0, l=1, l=2, and l=3 and are named the s, p, d, and f subshells respectively.
• The maximum number of electrons that can be accommodated by a subshell is given by the formula 2*(2l + 1).
• Therefore, the s, p, d, and f subshells can accommodate a maximum of 2, 6, 10, and 14 electrons respectively.
