Answer:
I can't draw diagrams on this web site but I can do with numbers I think. So an electron is moved from n = 1 to n = 5. I'm assuming I've interpreted the problem correctly; if not you will need to make a correction. I'm assuming that you know the electron in the n = 1 state is the ground state so the 4th exited state moves it to the n = 5 level.
n = 5 4th excited state
n = 4 3rd excited state
n = 3 2nd excited state
n = 2 1st excited state
n = 1 ground state
Here are the possible spectral lines.
n = 5 to 4, n = 5 to 3, n = 5 to 2, n = 5 to 1 or 4 lines.
n = 4 to 3, 4 to 2, 4 to 1 = 3 lines
n = 3 to 2, 3 to 1 = 2 lines
n = 2 to 1 = 1 line. Add 'em up. I get 10.
b. The Lyman series is from whatever to n = 1. Count the above that end in n = 1.
c.The E for any level is -21.8E-19 Joules/n^2
To find the E for any transition (delta E) take E for upper n and subtract from the E for the lower n and that gives you delta E for the transition.
So for n = 5 to n = 1, use -Efor 5 -(-Efor 1) = + something which I'll leave for you. You could convert that to wavelength in meters with delta E = hc/wavelength. You might want to try it for the Balmer series (n ending in n = 2). I think the red line is about 650 nm.

Explanation: The sun is the main source of energy
The orbital shape, i.e. the radial probability distribution, of the 2s sublevel shows it to be more stable than that of the 2p sublevel because it closer to The nucleus.
The nucleus of an atom consists of neutrons and protons, which in flip are the manifestation of more primary debris, known as quarks, which are held in affiliation through the nuclear sturdy pressure in positive solid combos of hadrons, referred to as baryons.
The nucleus of the atom, also called the atomic nucleus, is the small, dense, spherical center of an atom. The nucleus incorporates subatomic debris: the protons and the neutrons. Protons are definitely charged particles with a mass of about 1 amu (atomic mass unit).
It is composed of protons, which have a fantastic charge, and neutrons, which haven't any price. Protons, neutrons, and the electrons surrounding them are lengthy-lived particles found in all ordinary, clearly going on atoms.

Answer:
The eccentricity of the ellipse is 0.252.
Explanation:
The eccentricity of an ellipse (
), dimensionless, can be determined by means of the following expression:
(1)
Where:
- Distance between the foci, dimensionless.
- Length of the major axis, dimensionless.
If we know that 
and 
, then the eccentricity of the ellipse is:
The eccentricity of the ellipse is 0.252.
