Can someone actually help me with this? Question: What is the subatomic composition of technetium-100 (Z = 43), if a cation of Tc has lost three electrons?

i need to find the protons, neutrons, and electrons. :((

p = 43, n = 57, e = 40

Explanation:

Z is the number of protons. The number of neutrons, subtract Z from the isotope number (100). To begin with, protons and electrons are equal in an atom, but this atom lost three, so subtract 3 from Z.

Z= # of protons = 43

100 - 43 = 57 neutrons

43 - 3 = 40 electrons.

the answer is either b or c
