Your Questions About Atom Films

for film deposition how do I calculate rate of atoms being deposited?

it is a copper source being deposited on a substrate 10″ away

Do you remember seeing a film in science class in about grade 9 or 10, about atoms that lived in houses….?

I think they went to some kind of party?

Does anyone know the name of this film?

how would you feel if you found the following about the Atom Bomb were true?

For a few years now I have been looking into any information i can find on this story, since it involves a very sad story burried within.

1944, the US is trying to decide, if it is needed, how to transport an atomic bomb to Japan for most effect.
Airplanes at the moment were ruled out for weight problems.
The best solution at the time was considered a cargo ship.

Port Chicago, California: Black sailors worked the worst jobs in the navy, and were the ammunition handlers in the port. they were kept in horrible living conditions and treated more like slaves then naval personel.
cant remember the exact date)

one morning: A explosion rips through Port Chicago destroying a number of ships and most of the docks area.
After cleanup is done, 50 blacks refuse to return to work and are charged with Mutiny. Most would not live to see Bill Clinton pardon them.

Facts:

1. the commander of Port Chicago started out as a team member at Los Alamos (the place in new mexico where A bombs were tested), he was made commander of Port Chicago soon before that morning. After the explosion, he was given a commision. Word is his last assignment was part of the crew of the Enola Gay that dropped the first bomb on Japan.

2. A naval photographer was across the bay and caught the explosion and destruction on film.

3. Two odd containers were on the docks during that time, and both had very heavy security measures.The morning of the explosion- no secutiry.

4. A blinding white flash and mushroom cloud were reported from survivors of Port Chicago. (very nuclear sounding).

5. the rumble from the explosion (and the white light) were spotted and felt as far as 167 miles away at a mountain side post.

Theory put by some researchers: An atomic bomb was in the cargo holds but did not go off intentionaly. Instead the explosion from the ammunition exploding in a miss handling operation, cooked off the explosive charges around the warhead causing a nuclear reaction. However this part does not explain why the place was fully operational within days and to this day is a naval air station.

my question though is this.

what would you think if it was proven that a Atomic bomb, to test the effects on a port was done in the US?

here’s just one of the sources ive read.. there’s various info in it on it
according to at least one article that theory of not enough uranium is false.

a article said there was enough but never used, for 11 atomic bombs.

so testing one wasnt beyond belief.
thats Port Chicaco, California, not Port of Chicago.

Chemistry: Orbitals and Energy?

1) Which of the following metals (with their associated threshold wavelength) has the lowest work-function value?

K, 543 nm
Y, 410 nm
Os, 210 nm
Cs, 602 nm

2)Though Neon is a relatively small atom with a relatively high nuclear charge, it is difficult to add an electron to a neon atom. Which of the following is the best explanation of this phenomenon?

The neon atom is noble.

Neon has such a large number of electrons already that the electron-electron repulsion is too great to overcome.

The next electron added to neon would have to be placed in a higher energy level (the n=3 level).

The next electron added to neon would have to go into an s orbital, and s orbitals are harder to fill than p orbitals.

3)The work-function value for uranium metal is 3.63 eV. This energy is achieved with photons at a frequency of 8.77 x 1014 s–1 (near ultraviolet). If light of a lower frequency than this is applied, what will happen?

The kinetic energy of the electrons emitted by the uranium metal will be greater.

The current due to the photoelectric effect will disappear.

The current due to the photoelectric effect will be higher.

None of the above.

4) Which if the following is not a component of an s orbitals?

nodes.
radial nodes.
angular nodes.
energy levels.

5) What is the difference between a 2p and a 3p orbital.

The 3p orbital has two nodal planes, while the 2p orbital has only one.

The 3p orbital is farther from the nucleus than the 2p orbital.

The 3p orbital is a different shape than the 2p orbital.

Both A and C.

6) A molecule of oxygen gas (O2) has a velocity of 2800 m/s. What is its de Broglie wavelength?

4.5 × 10–12 m
2.4 × 10–37 m
1.2 × 10–59 m
9.9 × 10–56 m

7) Which of the following is the best explanation of why it is harder to remove an electron from an atom of neon than an atom of fluorine?

Neon has more electrons than fluorine, so it is less like to give one up.

It is harder to remove an electron from neon than fluorine because of increased nuclear charge (Z=10).

Electrons are easier to remove from elements that form diatomic gases, in general.

Removing an electron from neon would require formation of an unpaired 2p electron.
Which of the following statements correctly describes an observation of the photoelectric effect?

Shining a light on a metal such as potassium in a vacuum tube will create a current in a circuit as registered on an ohm meter.

Increasing the frequency of light shined on a metal will increase the number of electrons emitted but not their kinetic energy.

Increasing the intensity (or brightness) of light shined on a metal will increase the kinetic energy of the electrons emitted by the metal.

There is a frequency of light below which no electrons are emitted.

9) Determine the energy required to remove the electron from the 1s orbital of a Helium ion (He+).

5.45 x 10-19 J
2.18 x 10-18 J
8.72 x 10-18 J
4.36 x 10-18 J

10) Which of the following is not a consideration in the placement of electrons in an atom?

The energy requirements of a given arrangement of atoms
Hund’s rule
Pauli exclusion principle
Heisenberg uncertainty principle

11)Determine the frequency of light required to move the electron of the Be3+ ion from the n = 1 to the n = 4 orbital. The atomic number of beryllium is 4.

different; different
different; the same
It is impossible to determine the relative magnitudes of the energies of the different orbitals.

What do you think of my poem?

Zero

To liaison alone lighting slowly,
atoms,
molecular collections bonding eternal,
around condensate,
vast accounts,
casts.

Ends lines.

To channel one continual symmetry,
films,
synapses singing in endings,
through slits flinging nerves,
by dreams glide non crossed stones,
silences.

Not noises.
