Question

1. What is the largest possible value of m_{l} for an
electron in the n = 4 state?

2. Atoms can be ionized by thermal collisions, such as at the
high temperatures found in the solar corona. One such ion is
C^{+5} , a carbon atom with only a single electron. What is
the change in energy (in eV) of the first line in this ion’s
Paschen series? Consider that the ground state energy that is
necessary to ionize hydrogen is 13.6 eV.

3. An atom has an electron with m_{l} = 2 . What is the
smallest value of n for this electron?

**Plz answer all. don't have money for more. will give
thumbs up :)**

Answer #1

Atoms can be ionized by thermal collisions at very high
temperatures. One such ion is Cr23+, a chromium atom
with only a single electron.

greater than those of hydrogen?
(b) What is the wavelength of the first line in this ion's Lyman
series?
nm

Consider the first three energy levels of hydrogen (n = 1, 2,
3).
a) What photon energies can be observed from transitions between
these levels? Label these in increasing order as E1,
E2, and E3.
b) A hydrogen atom which is initially in the n = 2 level
collides with an aluminum atom in its ground state (the kinetic
energy of the collision is nearly zero). The hydrogen can drop to
the n = 1 level and ionize the aluminum...

A color television tube also generates some X-rays when its
electron beam strikes the screen. What is the shortest wavelength
of these X-rays in picometers, if a 33.9 kV potential is used to
