How did Einstein’s theory of general relativity change the way scientists look at gravitational force? He proposed that each object can have the potential of having a gravitational force.

He proved that gravity is the strongest force in the universe.

He presented the idea that gravity is just a curvature in space.

He concluded that gravitational forces are stronger closer to black holes.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
