    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).
