For a given principal quantum number or n, the corresponding angular quantum number or l is equivalent to a range between 0 and (n-1). This means that the angular quantum number for a principal quantum number of 2 is equivalent to:

l = 0 -> (n-1) = 0 -> (2-1) = 0 -> 1

So the answer is 0, 1

Answer from: macylen3900

0, 1

Explanation:

1) n and ℓ are two quantum numbers.

The quantum numbers are:

Principal quantum number (n)

Azimuthal quantum number (ℓ)

Magnetic quantum number (m)

Spin quantum number (s)

2) Principal quantum number (n), tells the main energy level, which is related with the size of the orbitals. It is also refered as the shell of the electrons.

The principal quantum number (n) may be an integer number among 1, 2, 3, 4, 5, 6, and 7.

3) Azimuthal quantum number (ℓ) tells the shape of the orbital. It is seen as the sub-shell.

This quantum number may be identified either by a number of a letter. These are the correspondences between the letter and the numbers.

quantum number (ℓ) orbital or subshell

0 s

1 p

2 f

3 d

3) The main energy level, n = 1, can only have one subshell: the s subshell. So, when n = 1, ℓ can only be 0.

When n = 2, ℓ can only be 0 or 1

When n = 3, ℓ can only be 0, 1, or 2.

And so on.

This is summarized by the following rule: the values of ℓ are 0, 1, 2, ... n - 1. This is any whole number less than n.

So, since the question states n = 2, ℓ can be 0 or 1 (orbitals s or p).

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
