Question

sodium is an element from group 1. it's atom and ion differ by??​

Answer 1

Answer:

As demonstrated here, a sodium atom (Na) has one valence electron in the third principal energy level. It is likely to achieve an octet in its outermost shell by losing its one valence electron. The cation produced in this way, Na +, is called the sodium ion to distinguish it from the element.
