5 True/False questions
Electronegativity → The attraction of a given atom for the electrons of a covalent bond.
Radioactive Isotope → occurs because the molecules with the greates energy leave.
Chemical Bonds → A chemical bond resulting from the attraction between oppositely charged ions.
Cohesion → The sticking together of molecules of the same kind, often by hydrogen bonds.
Matter → A compound resulting from the formation of ionic bonds; also called an ionic compound.
