If a krypton gas sample at 193 Kelvins and 1250 torr occupies 50.5 ml,
what is the STP volume?

What are the first two quantum numbers for the electrons located in subshell 4d? what are the first three quantum numbers for the electrons located in subshell 2s? how many electrons can be held in a sublevel l = 3? how many electrons can be held in the energy level n = 4? how many electrons in an atom can share the quantum numbers n = 4 and l = 3?

Place the elements below in order of decreasing ionization energy. aluminum(al) chlorine(cl) magnesium (mg) sulfur(s)

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
