I think the question is probably about "light elements".
The inner planets are relatively warm and small. This means they have not
been able to keep the lightest elements, hydrogen and helium, as gases.
they are larger but not rockier then the inner planets the outer planets are made of gas.
Inner planets are smaller and made of rock and metal, while outer planets are larger and predominantly made of gas and ice. Inner planets have few or no moons, while outer planets have numerous moons. Inner planets have solid surfaces, while outer planets do not have solid surfaces, instead having thick atmospheres.
Heavy elements.
No, those are the outer planets.
The four inner, rocky planets are also known as the terrestrial planets. These are; Mercury, Venus, Earth and Mars.
The inner planets Mercury, Venus, Earth and Mars are small, heavy and mostly made of rock. The outer planets Jupiter, Saturn, Uranus and Neptune are huge, light and mostly made of gas.
the inner planets made up of rocks while the outer planets are made up of gases and liquids.
The inner planets are all rocky planets. The outer planets are completely made up of gases. The inner planets are much smaller than the outer planets.
they are larger but not rockier then the inner planets the outer planets are made of gas.
No because the inner planets are made of rocky and hard substances and the outer planets are made of gassy lighter substances.
All inner planets are made of rock. (Earth, Mars, Venus, and Mercury)

An inner planet is mostly made of iron and has more mass than outer planets, outer planets are mostly made of gasses, makeing them have less mass. The inner planets are the planets between the asteroid belt and the sun
the inner planets are rocky and warm and the outer planets are made out of gas and is cold
