Why are gamma rays not affected by a magnet as they pass over It? A. Gamma rays do not
have enough mass to be affected.
B. Gamma rays do not have the right electrical to be affected.
C. Gamma rays are composed of only energy.
D. Gamma rays move too fast for anything to affect their pathway.

B

Explanation:

I think B is the answer because Gamma rays don't go for positive or negative charges. I am not sure about this because I had to search the question too. I hope this works for you.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
