Answer #1

20.

Q = n*e

n = excess electrons

e = charge on electron

Q = 14.3*10^19*(-1.6*10^-19)

Q = -22.88 C

21

Using ohm's law:

V = i*R

i = V/R = 29.9/44.4

i = 0.673 Amp

Does Bohr's theory of the hydrogen atom predict that it is possible for the electron in a hydrogen atom to orbit the nucleus with any possible radius? Yes, there are an infinite number of possible orbits, so that every radius is possible. O No, while there are an infinite number of possible orbits of different radii, the radii have only distinct values, not continuous values. O No, there are only a finite number of possible orbits of different radii. +-/1...

05 Question (4 points) When a hydrogen atom absorbs a photon of electromagnetic radiation (EMR), the internal energy of the atom increases and one or more electrons may be energized into an excited state. The release of this extra energy as the excited state electron transitions back to a lower energy state results in the emission of a photon. These energy changes are responsible for the emission spectrum of hydrogen (shown below) and are described by the Bohr equation. AE...
