Question

Tell me everything​ releated to metals and periodic table including elements , valency , electronic configuration​

Answer 1

In the initial period elements are classified as metal and nonmetal after then metalloid was discovered over a century.In the periodic table vertical columns are group and horizontal column are rows. the first group name akali with one balance electron in outermost shell I.e H=1,Li=2,1,Na=2,8,1 by this wwe know that as we go down the group the no.of shells will add but the valency remains one.In the same way as we go from left to right in a period the atomic radius will increase and electronegativity will increase and metallic character of element will decrease and it's just is that when we go from up to down in a period.
