Which of the following explains the process of radiation?

Question 3 options:

when heat gets transferred through objects that are touching

when the measurement of heat in the atmosphere goes down

when heat gets transferred through electromagnetic waves that move through space

when heat gets transferred through a liquid or a gas

When heat gets transferred through electromagnetic waves that move through space .

Explanation:

Radiation is the propagation of energy in the form of electromagnetic waves or subatomic particles through a vacuum or a material medium.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
