Question

which of the following shells is closest to the nucleus in a bohr model?
choose 1 answer:

a $n = 1$
b $n = 2$
c $n = 3$

Explanation:

In the Bohr model, the principal quantum number \(n\) represents the electron shell. As \(n\) increases, the distance of the shell from the nucleus increases. So, the shell with the lowest \(n\) value (\(n = 1\)) is closest to the nucleus.

Answer:

A. \(n = 1\)
