As you look down the column of gases, what pattern do you see in the melting point and density?

the awnser is group 12

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
