Answer 1

Answer:

Mark me as brainliest

Explanation:

First of all, we all know the bounding between protons and nucleus is very strong so protons cannot be added or removed. Only electrons can be moved.

now look the sign. it is +ve sign which shows removed.

Hence electrons haven been removed.

B) Q = ne

n = Q/e = (3*10^-9)/(1.6*10^-19)

n = 1.875*10^10 electroons .
