Question

Nuclei that have an excess of netrons can become stable by emitting what?

Answer 1

not by emiting but by losing or Han ng some electrons OK as always remember that only electrons can only be gained or lost and the electrons revolve around the nucleus 2. the whole mass of the atom is concentrated in the nucleus because the mass of the electrons is negligible the electrons in the outer most shell or orbit are the valance electrons (valence means to balance the atom . ) the electrons only lost or gain to complete an octet ( octet means eight electrons it means that the last shell should have eight electrons by losing or gaining electrons but the energy should be conserved there like sodium 2,8,1 so to complete 8 electrons in the outer most shell I have to lost or gain electrons so if I lose 1 electone so energy would be used less and it will become 2,8 so we completed 8 electrons in the outer most shell OK you understood tell me in the comments I have gave extra knowledge is it OK ( mark my answer as a brainliest answer pls ).
