Question
If an element contains one electron and one proton, what will be the charge of it?
- +1
- +2
- 0
- 1
Hint:
The charge of an atom that has one proton and one electron will be neutral.
The correct answer is: 0
- The number of protons and electrons determines the charge of an atom as they have opposite charges.
- If an atom has one electron and one proton, the positive charge of the proton will be neutralized with the negative charge of an electron.
- So the charge of the atom will be 0.
