Question

Na, Mg,Al,Si,are isoelectronic their ionic size follow the order​

Answer 1

Answer:

Na+ > Mg+2 > Al+3 > Si+4

Explanation:

because when charge is more, the size of ion will decreases, going with that, Na has single valancy hence, it has bigger size, similarly, Silicon has 4 valancy which means that it has lower ionic size. the order will be,

Na+ > Mg+2 > Al+3 > Si+4
