1.	an element has Z is equal to 12 and a is equal to 26 draw a diagram showing the distribution of electrons in the orbits what is the valency of element and why? if this element X combined with another element Y whose electronic configuration 2, 8, 7 what will be the formula of the compound thus formed? state how did you arrived to this formula?
Answer» 6Mg'Z=12Orbits= K(2), L(8), M(2)VALENCY= 2 Group No.=2Block= sMg+S=MgS, (S's velocity is 2MgCl2
