If Ac-208 loses a neutron, what is left?

Answer 1

Ac 207

The atom stays the same element when a neutron is lost because it only affects the nuclear mass and not the protons. ( possibility more radioactive)

Another isotope of actinium...

We start with #""^208Ac#...and it undergoes some nucular process...

#""_89^208Acstackrel"nuclear process"rarr""^207Ac+""_1^0n#

I am no nuclear chemist...and my understanding may be naive. However, AFAIK, there are no stable actinium isotopes, and the species can undergo transmutation to francium, thorium, and radium. In the given process, there was no change in #Z# per se, and we are still left with an actinium isotope...

Ac-208 becomes Th-207 if it loses a neutron.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
