Question

in the formation of XY2 atom X denotes one electron to each Y atom.show the electron dot structure of X and Y and the formation of XY2 what is the nature of bond in XY2? write any three properties of XY2.the electronic configurations of two elements X and Y are as follows :

x-2,8,2

y-2,7

Answer 1

ionic bond.
ionic compound
soluble in water
donot conduct electricity

( draw arrow marks from ions of x to y ad two ys )
X-2e​---> X+2
Y+1e​--->Y-

[X+2] [Y-]2
