(c) When the electrons have their maximum possible total ms, what is the maximum total ml?
(d) Suppose one of the d electrons is excited to the next highest level. What is the maximum possible total ms, and when ms has its maximum total what is the maximum total ml?

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.

Wave functions describe orbitals in a hydrogen atom. each function is characterized by 3 quantum numbers: n, l, and ml. if the value of n = 2: the quantum number l can have values from to . the total number of orbitals possible at the n = 2 energy level is .

Achlorine atom has 17 protons and 18 neutrons. what is its mass number? what is its atomic number?
