Answer:
The possible values of l are 2 and 3
Explanation:
Each electrons have four quantum numbers:
- n: the principal quantum number, which value matches with the energy level of the electron.
- l: the secondary quantum number, which value can be from 0 to n-1
- m: the magnetic number, which value can be from -l to l
- sp: the spin number which value can be -1/2 or +1/2
In this case, n=4 so the values of l are:
l=0, 1, 2, 3
Now, if:
- l=0 the value of m is m=0
- l=1 the values of m are m= -1, 0, 1
- l=2 the values of m are m= -2, -1, 0, 1, 2
- l=3 the values of m are m= -3, -2, -1, 0, 1, 2, 3
Being all that said, l can be either equal to 2 or 3
Answer:
Electrons
Explanation:
In an atom there would be three subatomic particles: Neutrons, electrons, protons. The smallest and lightest in terms of mass is electrons. This is because the nucleus is comprised of the protons and the neutrons, these have a greater mass than electrons as electrons has very little mass that can considered to be 0.
