What makes radiant energy different from other forms of energy? a. it can travel through space. b. it is transferred by air circulation. c. it requires contact to transfer heat. d. it flows from a cooler object to a warmer object.

It can travel through space

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.

All the elements are arranged by melting points on the periodic table. in row they go from metals to gasses. in the row from sodium to argon, sodium is more reactive than the one on its right, magnesium.
