Question

describe the formation of the compound: aluminum oxide, carbon tetrachloride, sodium carbonate, ammonium sulphate, calcium oxide​

Answer 1

Answer:

formation of compound

aluminium oxide :we need two atoms of aluminum and 3 atoms of oxygen to form aluminium oxide

it is an ionic bond as aluminum is a metal and oxygen is a non metal ,therefore aluminium oxide is a ionic compound

two atoms of aluminum loses three electrons to chlorine to attain it's stability

3 atoms of oxygen gains two electrons each from two atoms of aluminum

carbon tetrachloride

it is a covalent bond

atom of carbon needs four electrons to attain stability

atom of chlorine needs one electron to attain stability

so carbon and chlorine share there electrons and form carbon tetrachloride

sodium carbonate

sodium electronic configuration =2,8,1

carbon=2,4

oxygen =2,6

2 atoms of sodium and 3 oxygen atom and one carbon atom forms sodium carbonate

ammonium sulphate

(NH4)2SO4

two atoms of nitrogen

8 atoms of hydrogen

1 atom of sulphur

4 atoms of oxygen

forms ammonium sulphate

calcium oxide

calcium electronic configuration =2,8,8,2

oxygen =2,8,6

calcium loses two electrons to oxygen and attains its stable electronic configuration

oxygen gains two electrons from calcium and attains it's stable electronic configuration

thereby it forms calcium oxide
