Which of the following set of quantum numbers (ordered n, ℓ, mℓ, ms) are possible for an electron in an atom? check all that apply
a)2, 1, -2, 1/2
b)2, 1, 0, 1/2
c)3, 2, 0, -1/2
d)-2, 1, 0, -1/2
e)2, 4, 1, -1/2
f)2, 1, 0, -1
g)4, 3, 4, -1/2
h)3, 1, 0, -1/2

i'm not sure

explanation:

i'll try whatever you got

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

mark brainliest and have a great day!

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
