Answer:
Noble gases are the least reactive of all elements
Explanation:
because they have eight valence electrons, which fill their outer energy level
Answer: The Answer is A.
Explanation:
The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy. Equivalently, the longer the photon's wavelength, the lower its energy.
