Questions and Answers

What is the relationship between ml and l in terms of the number of values they have?

ml has twice the values of l

ml has (2l+1) values, the same as the number of orbitals per subshell (correct)

ml has one more value than l

ml has one less value than l

According to Bohr, what is an orbit in an atom?

A fuzzy area where electrons are randomly found

A precise path around the nucleus where an electron moves (correct)

An undefined region with no electrons

A specific location within the nucleus

Why do Bohr orbits have no real meaning?

Due to the existence of multiple electrons in one orbit

Because they are too small to observe

Because their precise description is impossible according to Heisenberg uncertainty principle (correct)

Because they exist outside the atomic structure
