I believe the answer is "When a neutral atom looses an electron to another neutral atom, two charged atoms are created."
Answer:
2.13 x 10^-19 J or 0.53 eV
Explanation:
cut off wavelength, λo = 700 nm = 700 x 10^-9 m
λ = 400 nm = 400 x 10^-9 m
Use the energy equation

Where, K be the work function



K = 2.13 x 10^-19 J
K = 0.53 eV
The correct answer would be A. endothermic because endothermic is-<span>(of a reaction or process) accompanied by or requiring the absorption of heat. Hope this helps!:) If you need any more just tag me.

Chemical because rust is also called iron oxide (Fe2O3) and it occurs when oxygen bonds with iron atoms
