Challenge: Think about the factors that control atomic radius and the patterns you’ve seen. Why does the atomic radius decrease as electrons are added to a shell

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

Answer///precipitate;

Im here for points, sorry i dont have the answer ; /
