An element is a pure substance that cannot be broken down into anything simpler. They contain the same amount of atoms in their nuclei. They cannot be broken down by a chemical process.

A compound consists of two or more elements that are chemically combined in nature.

From the given diagrams, the white circles represent the elements and when combined with a dark circle, they become a compound.

Therefore, by looking at the diagrams carefully, we can now understand the classification of element, compound, or mixture of both.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
