AIts neutron
BIts electron
CIts nucleus
DIts whole shell
Answer & Solution
Correct answer: B. Its electron
1. The commonest isotope of hydrogen has one proton and one electron, and no neutron.
2. Removing the electron leaves the bare proton behind.
3. That bare proton is the hydrogen ion the whole acid-base model moves around.
4. Losing the nucleus would leave nothing of the atom at all.
