If the principal quantum number is n = 3, what are the name(s) of the subshells?

Ede4ka [16]

The name(s) of the subshells are s,p and d

<h3>Further explanation</h3>

Each orbital in an atom consists of 4 quantum numbers

n is the principal quantum number.

l is the angular momentum / azimuthal quantum number

ml, the magnetic quantum number

ms, the electron-spin quantum number

Value of n: positive integer

value of l: s = 0, p = 1, d = 2, f = 3 , ..(n-1)

ml value: between -l to + l

ms value: +1/2 or -1/2

n=3, then the possible value of l is a maximum of n-1 = 3-1 = 2

So the value of subshells = 0,1 and 2

Element X has two isotopes. The table gives information about these isotopes.

Sedbober [7]

Answer : The average atomic mass of an element X is, 63.546 amu

Solution : Given,

Mass of isotope X-63 = 62.9296 amu

% abundance of isotope X-63 = 69.15% = 0.6915

Mass of isotope X-64 = 64.9278 amu

% abundance of isotope X-64 = 30.85% = 0.3085

Formula used for average atomic mass of an element X :

$\text{ Average atomic mass of an element}=\sum(\text{atomic mass of an isotopes}\times {{\text { fractional abundance}})$

$\text{ Average atomic mass of an element X}=\sum[(62.9296\times0.6915)+(64.9278\times 0.3085)]$

$\text{ Average atomic mass of an element X}=63.546amu$

Therefore, the average atomic mass of an element X is, 63.546 amu
