Question

What is true about ionic and covalent compounds?

Covalent compounds are formed from nonmetals while ionic compounds are formed from
nonmetals and metals
Covalent compounds contain oppositely charged atoms while ionic compounds contain
neutral atoms
Covalent compounds are very reactive with water while ionic compounds react very well
with oxygen gas
Covalent compounds are good conductors of heat and electricity while lonic compounds
are poor conductors

Answer 1

Covalent compounds are formed from nonmetals while ionic compounds are formed from nonmetals and metals (Specifically, a metal transfers electrons to a non-metal).
