Ans 56- Element W will most likely to form a compound with hydrogen with the formula H2W . As we know that Y represents group 18 that is group of noble gases than W will represent group 16 with elements Oxygen , Sulphur , and selenium ... And we know that they forms compound with hydrogen as H2O H2S and so on .
61- the formula foe the compound will be XY . For ex: neon fluoride (FNe-)
