Ionic bonds are forces that hold together electrostatic forces of attractions between oppositely charged ions. Ionic bonds have an electronegativity difference greater than or equal to 2. Covalent bonds have an electronegativity difference that is less than 2.
D. It has mass, takes up space, and can be seen without a microscope.
The answer is B) Electrical outlets contain metal wires that are good conductors of electricity. In order to promote electrical safety, the parents covered the outlets with plastic, an insulator that prevents electrical current from flowing to another object.
(3) Nickel, being a transition metal, is a good conductor of electricity and is solid at STP.
