The belоw imаge represents аn аtоm оf a specific hypothetical element and its own cation. Which image represents the cation?  M represents the cation  L represent the cation  What supports your choice?   Cations are larger than their neutral atom Cations are smaller than their neutral atom   Why does this occur?   Because cations lose electrons from the outer most shell, the remaining electrons have a stronger attraction to the nucleus and are pulled closer, thereby making the ion small Because cations gain electrons, the incoming electrons will be repelled by the existing electron and therefore the shell will expand to accommodate them
