Genius! There are \(3\) protons and \(4\) electrons. So, the net charge will be \(\left(3 \times \left(+ \mathrm{C}\right) \right) + \left(4 \times \left(- \mathrm{C}\right) \right)\) \(= 3 \, \mathrm{C} - 4 \, \mathrm{C} = -1 \, \mathrm{C}\)
But, scientists observed that atoms are electrically neutral. That is, the net electric charge of atoms is zero.
If the atom is electrically neutral, what can we say about the electrons and protons in an atom?
  • There are no electrons and protons in an atom
  • The electrons and protons in the atom have no charge
  • There is an equal number of protons and electrons in an atom
  • There are no electrons in an atom. There are only protons.
