Can metals take away electrons from non metals?

Well no because if metals lose electrons, any non-metal sources/items gain electrons from the metal.

Metals tend to lose electrons and non-metals tend to gain electrons, so in reactions involving these two groups, there is electron transfer from the metal to the non-metal

Explanation:

the answer is b & c i believe : )

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.
