Salad, a bag of different colored pebbles or sand, etc
5 Valence electrons .......... Hope it helps, Have a nice day:)
Heat= latent heat of fusion+sensible heat+ latent heat of vapourization
=(79.7*5)+(5*100*1)+(540*5)
=3598.5 cal
It is ionic bond because of Na valency and it is alkali metal and cl is non metal and it’s valency , they both share electron and make ionic bonding .
