I believe that when a nucleus undergoes a nuclear decay by gamma rays the atomic number of element remains the same. Atomic number is the number of protons of a given atom of an element. Gamma decay unlike alpha and beta decay does not have an effect on the mass number and atomic number of an atom.
Answer:
In oxidation reduction reactions, one species gets reduced by taking on electron(s) and another species gets oxidized by losing electrons. The movement of electrons can be used to do work. ... The electron flow can be run through a wire and these electrons can be used to do work (like run a battery). Hope this helps.

Answer:
D.) small, dense negative nucleus surrounded by a diffuse positively charged cloud
Explanation:
I am not 100% sure but the reason I think this is the answer is because Protons and Neutrons are in the nucleus. Protons being positively charged and neutrons being negatively charged. Again, I do not know for sure, but I think D is the answer.
Answer:
1080 photons
Explanation:
ΔE = hc/λ => Energy per photon
h = 6.63 x 10⁻³⁴ j·s
c = 3 x 10⁸ m/s
λ= 535 nm = 5.35 x 10⁻⁷ m
ΔE/photon = (6.63 x 10⁻³⁴ j·s)(c = 3 x 10⁸ m/s)/(5.35 x 10⁻⁷ m) = 3.71 x 10⁻¹⁹ j/photon
For #photons in 4.00 x 10⁻⁷ j = (4.00 x 10⁻⁷ j) / (3.71 x 10⁻¹⁹ j/photon) = 1076 photons ≅ 1080 photons (3 sig. figs.)
