Any element in group 1 has just one valence electron. Examples include hydrogen, lithium, Li, and sodium. Any element in group 18 has eight valence electrons. Detailed Solution. Valency of an element can be defined as “Number of hydrogen atoms (or) chlorine atoms (or) double the no. of oxygen atoms with which one atom ...
