Describe how the molecular models you assembled are similar to real molecules. They model how real molecules are.

Atoms models are bigger but they don not match the true or positive way of atoms. to make them visible scientists make their models that resembled with the real ones.

Explanation:

Molecules are microscopic entities and only can be seen under a  microscope.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
