Question

Hydrogen has only one electron in its only (and outer) electron shell. If a hydrogen atom were to absorb a small amount of energy, where would Bohr say the electron would go?

A. fly off the atom
B. nowhere, it would just speed up.
C. spiral inwards towards the nucleus
D. move up to another shell that would form

Answer 1

D. move up to another shell that would form

Step-by-step explanation:

An atom has protons, neutrons and electrons. Protons and neutrons are present in the nucleus and electrons orbit the nucleus in fixed shells. An electron can jump to higher shell when it gains energy and lower one when it loses energy. Thus, when single electron in hydrogen atom is given a small amount of energy, it would jump to another higher shell.
