they were lost from the nucleus

Answer:

4.Outside the nucleus

Explanation:

The atoms have three subatomic particles: neutrons, protons and electrons.

Electrons in an atom are outside the nucleus, in a region that surrouns the nucleus. If electrons are lost, they are lost from outside the nucleus.

Inside the nucleus are only neutrons and protons, not electrons.
