Question

An atom X with atomic number 20 combines with atom Y with atomic number 8 draw the dot structure for the formation of the molecule XY​

Answer 1

THE ELECTRON DOT STRUCTURE OF XY IS SHOWN BELOW

the electronic  configuration of X is

X: 1s2,2s2 2p6,3s2 3p6, 4s2

x will lose 2 electron to form X2+

the electronic  configuration of Y is

Y: 1s2,2s2 2p4

Y will gain 2 electron to form Y2-

 X2+ + Y2- gives XY

the electron dot structure is shown in attachment
