As in: Helium is a gas but Lithium is a metal, even though they’re right next to each other on the Periodic table.
Or: Carbon is a gas but Silicon is a mineral, even though their chemical behavior is exceedingly similar due to their similar position (on different rows) of the table?
In: Chemistry
Their chemical behaviour isn’t very similar due to changing nucleus sizes, numbers of electron shells etc though, that makes the strength of the forces/bonds between atoms/molecules of each element different and therefore they’re in different states at the same temperature.
