# B Paradox in the nuclear activity

good evening everybody!!!
i'm studying these days the nuclear activity and this amazing world where an atom try to find its/her stability !!!!
so i came across the famous radiations but then stoped by something i didn't quite understand!!
when an atom release a beta radiation a negative one for example didn't she become unstable but from a charge view? ( when a neutron become a proton which means a one more + will be add which also mean that the atom needs a one more electron ?! nonetheless she release a one !!!! isn't that a paradox?!
thank you!

Atoms which contain an unbalanced number of protons and electrons are called ions. The energy that it takes to make an ion is minuscule compared to the energies involved in a nuclear transition. It is literally the difference between dynamite and a nuclear weapon.

### Bandersnatch

When a neutron decays through the beta- interaction, you have:
$n^0 -> p^+ + e^-$
So the charge is conserved on both sides.

oh yeah !!! i see what do you mean and that quite solve my problem !!! thank you!!
but is this electron is new formed? if it is a yes from where "he" came?

so isn't an ion an atom that gain or lose an electron???

If an atom gains or loses an electron, it becomes an "atom which contains an unbalanced number of protons and electrons" so this is consistent with what Dale said.
