I am having some trouble with some questions and need some help.
A neutron with a mass of 1.68 x10(27) exponent kg moves from a nuclear reactor with a velocity of 3.22 x10 (3) exponent m/s. What is the Broglie wavelength?
Also, I need to write tge complete electron configuration for a. neon b. sulfur and c.calcium
Thanks. I don't understant this is not that im being lazy

deBroglie wavelength= plancksconstant/momentum
the velocity is low, so relativistic effects can be ignored.
electronic configuration. I don't know if you need to learn how to do it from memory, or just need those atoms.
I will assume you need the algorithm.
