You are given the reaction cu + hno3 cu(no3)2 + no + h2o. which element is oxidized? which element is reduced?

The element  which is oxidized   and  reduced in the equation below   is

Cu  + HNO3 = CU(NO3)2 + NO +H2O

 Cu  is  been oxidized  while   HNo3  is reduced

Cu is oxidized  because  it move from  oxidation  state zero to  oxidation state of  positive  two (2^+) .  HNO3  act  as  the oxidizing agent  therefore   it oxidizes   Cu  while itself  is  reduced  by Cu

Nonmetals usually react by gaining electrons

The atomic nucleus made up from protons (yellow) and neutrons (blue) and held together by nuclear forces. nuclear forces (also known as nuclear interactions or strong forces) are the forces that act between two or more nucleons. they bind protons and neutrons (“nucleons”) into atomic
