Acommon mineral of barium is barytes, or barium sulfate (bas04). because elements in the same periodic group have similar chemical properties, we might expect to find some radium sulfate (ras04) mixed with barytes because radium is the last member of group 2a. however, the only source of radium compounds in nature is in uranium minerals. explain why this is so.

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.
