The process of ionic bonding is not the same as the process of metallic bonding. Which of the following statements is true about these processes?

1. In ionic bonding, only ions of the same element combine to form a compound.
2. In metallic bonding, valence electrons can move freely between atoms.
3. Substances formed through ionic bonding are not considered compounds.
4. In metallic bonding, electrons are transferred between elements in fixed ratios.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
