If an atom contains one electron and one proton, will it carry any charge or not?

Text Solution

Verified by Experts

An electron is a negatively charged particle, whereas a proton is a positively charged particle. The magnitude of their charges is equal. Therefore, an atom containing one electron and one proton will not carry any charge. Thus, it will be a neutral atom.

A hydrogen atom contains one proton and one electron. It may be assumed that the electron revolves in a circle of radius 0.53 angstrom (1 angstrom = 10^(-10) m and is abbreviated as A) with the proton at the centre. The hydrogen atom is said to be in the ground state in this case. Find the speed of the electron in the ground state of hddrogen atom.
