Question

please give correct answer I have my exam tomorrow​

Answer 1

Answer:

(i) l = n-1

(ii) n

Explanation:

(i) From the given table we can see that 'l' is one less than 'n' therefore relation is l = n-1.

(ii)The principle quantum number serves to determine the size of the orbital, or how far the electron extends from the nucleus. The higher the value of n the further from the nucleus we can expect to find it. As n increases so does the energy required as well because the further out from the nucleus you go the more energy the electron must have to stay in orbit.

The principle quantum number describes size and energy, but the second quantum number describes shape. The subshells in any given orbital differ slightly in energy, with the energy in the subshell increasing with increasing l. This means that within a given shell, the s subshell is lowest in energy, p is the next lowest, followed by d, then f, and so on. For example:

4s < 4p < 4d < 4f ---> increasing energy
