I need someone to check my answers and help me with the questions I couldn't answer.

What is the max. # of electrons located in the groud state of

a) an orbital 2
b) d sublevel 10
c) Be atom 4 because 1s^2 2s^2 = 4 electrons
d) 3rd energy level = 10
e) f sublevel 14
f) a Ca atom 2
g) 4p sublevel of As 3
h) 3d sublevel of Cr 4
i) 5s sublevel of Sr 5 because the last one is 5s^2
J) 5th energy level of Br ?
k) 4d sublevel of Cd ?

At first sight abce are OK, others are either wrong (like d) or require checking periodic table (like gh).
