What is the charge and location of an electron in an atom?
Negative, outside nucleus
An electron carries a negative charge of \(1.6 \times 10^{-19}\) C. In Rutherford's and Bohr's models, the positively charged protons and neutral neutrons sit in the small, dense nucleus at the centre, while the electrons revolve around it in shells (energy levels) outside the nucleus.
"Positive, inside nucleus" describes a proton, and "Neutral, inside nucleus" describes a neutron. No negatively charged particle is present inside the nucleus.
Hence, an electron is negative, outside nucleus.
