✔ 最佳答案
ionic =metal+non-metalcovalent=non-metal+non-metal
1. NaCl is an ionic compound
Na=metal, Cl=non-metal
2. H2O is an covalent compound
H=non-metal O=non-metal
3. MgBr2 is an ionic compound
Mg=metal, Br=non-metal
4. FeS is an ionic compound
Fe=metal, S=non-metal
5. MgS is an ionic compound
Mg=metal, S=non-metal
6. HF is an covalent compound
H=non-metal F=non-metal
7. Al2O3 is an ionic compound
Al=metal, O=non-metal
8. Li3P is an ionic compound
Li=metal, P=non-metal
9. CaCl2 is an ionic compound
Ca=metal, Cl=non-metal

non-metal combined with metal is IONIC BOND
non-metal combined with non-metal is COVAENT BOND
thus 1,3,4,5,7,8,9 are ionic, 2,6 are covalent
non-metal combined with non-metal is COVAENT BOND
thus 1,3,4,5,7,8,9 are ionic, 2,6 are covalent
