3) ok so in the book we are told a diameter of 2.9 inches for a nucleus of of an atom that is 2.5 miles

1 mile = 1.609 km
1 inch = 2.54 E-5 km

2.9 inches = 7.366 E-5 km
2.5 miles = 4.0233 km

the distance around the earth at the equator is approximately 40,074 km according to here

40,074 km / 4.0233 km = 9,960.4

so 9,960.4 x 7.366 E-5 km = 0.73308 km

4)
a quark makes these up, the six flavours are up, down, charm, strange, top, and bottom. (Their names were chosen arbitrarily based on the need to name them something that could be easily remembered and used.)

5)
protium is required for ammonium.
deuterium is used in the manufacturing of nuclear weapons.
tritium is used in flares, emergency lights, exit signs as a source of light.

on a side note: apparently "every time you view a galaxy or system, you use 10 Deuterium" according to this gaming site here I can't begin to think how much of this deuterium i've wasted looking at the night sky.

6)
The reasoning the average atomic mass needs to be a weighted average is because of the possibility of the various isotopes being in a similar compound. This value makes a generalization to simplify the additional properties of the relative amu.

7)
24-Mg 78.99% = 19 amu
25-Mg 10% = 2.5 amu
26-Mg 11.01% = 2.8 amu

total = 24.3 amu

8)
question doesn't exist? free points? the answer is true

9)
There are no metals normally present as such in the body, except those put there during surgery.

These are the elements present in a human
1. Oxygen (65%)
2. Carbon (18%)
3. Hydrogen (10%)
4. Nitrogen (3%)
5. Calcium (1.5%)
6. Phosphorus (1.0%)
7. Potassium (0.35%)
8. Sulfur (0.25%)
9. Sodium (0.15%)
10. Magnesium (0.05%)
11. Copper, Zinc, Selenium, Molybdenum, Fluorine, Chlorine, Iodine, Manganese, Cobalt, Iron (0.70%)
12. Lithium, Strontium, Aluminum, Silicon, Lead, Vanadium, Arsenic, Bromine (trace amounts)

vitamin b-12 is in metallic cobalt, the possibility of me consuming it is there in when I eat my wheaties.

10.
these refer the placement of the electrons i really dont know how to describe this further

11.
I cant find this one

12.
These values depend on the element in quesiton

every orbital holds a max of 2 electrons

1s = 2
2s = 2
2p = 6
3s = 2
3p = 6
4s = 2
3d = 10
4p = 6
4d = 10
4f = 14

shell 1 = 2
shell 2 = 8
shell 3 = 18
shell 4 = 32

13.
there are 10 subshells filled
there are 16 orbitals filled
there are 32 electrons

14.
Billions?
I'm at a loss how to solve this one

Bonus
The thing I've noticed most is the fact they like to combust. The higher on the periodic table the greater the combustion, simply because the higher the element the more energy it contains.
