50pts I'm really frustrated.. I have to complete this test. I will link to extra points if you help me!! Please, only answer if you know you are correct! I need a good grade in this class to pass!
Which statement is generally true concerning ionic and covalent bonds?
Ionic bonds are created between ions with the electrons being shared equally between atoms.
In covalent bonds, the atoms are held together by electrostatic attraction.
Covalent bonds are stronger than ionic bonds.
It takes more energy to break an ionic bond than a covalent bond.
