Question

fill in blanks The principal guantum number of an atom is related to the

Answer 1

Answer:

Answer: The principal quantum number, n, describes the energy of an electron and the most probable distance of the electron from the nucleus. In other words, it refers to the size of the orbital and the energy level an electron is placed in.

this is the answer mark me as brainliest please

Answer 2

$\sf\huge\bold{Question?}$

The principal quantum number of an atom is related to the:

A size of the orbital

B spin angular momentum

C orientation of the orbital in space

D orbital angular momentum

$\sf\huge\bold{Answer:}$

$\fbox{⟶option A represents the correct answer}$

Explanation :

Principle Quantum number ( n ) represent the name, size and energy of the shell to which the electron belongs.

Higher the value of ' n ' greater is the distance of the shell from the nucleus.

The principal quantum number 'n' represents orbit number hence, determine the size of orbitals. The principal quantum numbers are represented by the letters 'K, L, M, N' or equal to 1, 2, 3, 4, etc.

The maximum number of electrons that can accommodate in a principal energy shell is given by
