Question

4. The given element form strongest basic oxide among Mg,
Si, Na, Cl Ar
a.Mg
b. Ci
d. Ar
c. Si​

Answer 1

Hi,

Among Na,Mg,Cl,Ar,Si... Na forms the most basic oxide because Cl is a non metal and so forms acidic oxides,Ar is a noble gas so doesn't form any oxide, Si is a metalloid so forms amphoteric oxide and Mg too forms basic oxide but since it belongs to grp 2 of periodic table, its oxide is not as basic as sodium oxide.

Among Mg,Si,Cl,Ar .... Mg forms most basic oxide.

Hope it helps
