What is the correct representation for the sub shell with n=2 and i= 1

“n” represents the energy level of any atom.

And “l” represents the sub levels within any energy level.

n = 1 would mean first energy shell or level.
n = 2 would mean second energy level. Similarly, n =3 would mean third energy level and so on.

“l” can have values 0,1,2,3 so on
l = 0 means “s” sublevel
l = 1 means “p” sublevel
l = 2 means “d” sublevel
l = 3 means “f” sublevel

Now let’s see the question... n = 2 and l = 1 means 2nd energy level and within that level he is talking about p sublevel. So the correct representation is

“2p”..

The answer is 2p

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
