Why are elements on the periodic table not arranged by mass? (1 point) This would not allow all of the elements with similar properties to be lined up with each other. This would not allow all of the elements with similar properties to be lined up with each other. Atoms are so small that it would make little sense to talk about their mass. Atoms are so small that it would make little sense to talk about their mass. Atoms with similar masses are so different from each other that this would lead to a random arrangement of atoms. Atoms with similar masses are so different from each other that this would lead to a random arrangement of atoms. Similar elements have such different masses that this would lead to a completely random arrangement of elements.

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.
