Question

Which one of these systems has the most negative charge?

a) 2 electrons b) 2 electrons, 2 protons c) 5 electrons d) 5 electrons, 2 protons

Answer 1

The system with the most negative charge is d) 5 electrons, 2 protons. Since electrons have a negative charge and protons have a positive charge, having more electrons than protons will result in an overall negative charge for the system.
