in this equation Ephoton=hv what does v stand for

Answer 12

frequency

Question 13

what id the excited stage

Answer 13

The excited state can commonly take the form of the electron jumping from its original energy level or orbital

Question 14

what is an orbital

Answer 14

the “rings” that the electrons jump to when excited

Answer 15

An anion is an atom or a molecule which is negatively charged

Question 16

what is cation

Answer 16

A cation is an atom or a molecule which is positively charged
