The maximum number of electrons in a subshell is given by the expression

Question

The maximum number of electrons in a subshell is given by the expression (A) 4l -2 (B) 4l + 2 (C) 2l + 2 (D) 2n2

Tardigrade Admin · Accepted Answer

The number of orbitals in a subshell = (2l + 1) where, l = azimuthal quantum number Since, each orbital contains maximum two electrons, the number of electrons in any subshell = 2 × number of orbitals = 2 (2l + 1) = 4l + 2

Q. The maximum number of electrons in a subshell is given by the expression

$4 l - 2$

$4 l + 2$

$2 l + 2$

$2 n^{2}$

The number of orbitals in a subshell $= (2 l + 1)$
where, $l =$ azimuthal quantum number
Since, each orbital contains maximum two electrons, the number of electrons in any subshell
$= 2 \times$ number of orbitals
$= 2 (2 l + 1)$
$= 4 l + 2$

Q. The maximum number of electrons in a subshell is given by the expression

4l−2

4l+2

2l+2

2n2

The number of orbitals in a subshell =(2l+1) where, l= azimuthal quantum number Since, each orbital contains maximum two electrons, the number of electrons in any subshell =2× number of orbitals =2(2l+1) =4l+2

$4 l - 2$

$4 l + 2$

$2 l + 2$

$2 n^{2}$

The number of orbitals in a subshell $= (2 l + 1)$
where, $l =$ azimuthal quantum number
Since, each orbital contains maximum two electrons, the number of electrons in any subshell
$= 2 \times$ number of orbitals
$= 2 (2 l + 1)$
$= 4 l + 2$
