1)Name two types of molecular compounds.
2)Name a group of elements on the periodic table.
3)The atomic number of an element gives what information about that element?
4)What else could you call a hydrogen atom that has lost its electron?
[/QUOTE]
I’m not exactly sure what you mean about “types of molecular compounds”. Are you speaking about how they bond, like ionic or hydrogen bonds and that sort of stuff? Or any molecular compound like Salt (NaCl) and Water (H2O)? (which is an ionic bond and a hydrogen bond respectively, I believe)
Stomach kicks it off, Duodenum leads to… and this is where I’m taking a stab, jejunum; then ileum then, obviously, colon? (please lord, I don’t ask for much).
Hemoglobin contains Iron.
The lightest: Helium
Mercury; and I think there was a thread just recently that mentioned Bromine?
In QM, one can never know the position and the velocity of a sub-atomic particle, such as an electron, at any given moment. The more you detect one aspect, the less you can detect the other.

Correct!
Nice!
Si
Both are correct.
Very nicely done.
That’s a +5 right there to my -3, so +2 i believe. Though this means the questions must get harder again!

1)Clarification: I’m looking for the names for the two different ways atoms can join to form a molecule. Simply naming a compound won’t count unless you also give me the way in which it bonds.
2)Check
3)Check
4)Bzzzt. A positron is the antimatter counterpart of an electron. A hydrogen atom that has lost its electron is a proton.

Well ionic is right but a hydrogen bond is a weak bond formed with an electronegative atom and a hydrogen atom. It’s the force that makes water molecules stick to other water molecules but doesn’t make the molecules themselves stick together. So unless someone tells me that I’m being a hard-ass, I’ll rescore.

Wow. Even when you explain it, my head is burning. If you don’t think my answer was close enough to correct, then keep yer score, otherwise, don’t be too hard on yourself! But you leave me curious, what sort of bond is a water molecule.
P.S. I actually got the explanation i think, it keeps the water molecules together, but not the hydrogen and oxygen atoms, right?

Did you even want to take a shot at #11? I’ll wait for you to ring in on that one, but i’ll score the rest:
11. What do Plasma B Cells do?
[/QUOTE]
Whoops! I totally missed it. Although it’ll probably put you in the hole.
Not sure if it has to do with the blood, but it’s the only time I ever hear plasma. I’ve heard white blood cells called T cells. And the only other blood cell I can think of are platelets which induce blood clotting. I’ll go with platelets, although I’m probably way off.
ETA: I couldn’t wait and looked it up. So sorry! Looks like they form in the bone marrow and pump out antibodies. Stoopid biology. Looks like I got some boning up to do (pun intended).

I think I know this: Australia.
Isn’t this the locomotion of a cell?
Wow. Um… thinking… Fast-twitch, Slow-twitch (?), and involuntary?! I’m guessing quadriceps, biceps, and heart respectively. (I’m sure I made a mess of that.)
Causes beating?
Hrmm, Speed is the over all movement of something (like the spinning of a wheel on a vehicle), and velocity is the speed of something in a certain direction of motion (how fast that vehicle is moving along a certain axis)?
Simple explanation is that the make up of our atmosphere happens to be good at absorbing longer wavelengths of light, and scattering/diffusing the shorter, bluish wavelengths.

It’s times like these I could kick myself. I had, verbatim, Stone Age, Bronze Age, and Iron Age typed in at one point. Then I figured that couldn’t be it and erased it for fear of shame, as I didn’t think the bronze and iron age were considered pre-historic!

Twould be covalent bonds that keep the atoms together. With NaCl, a chlorine atom that has lost an electron and has a positive charge is attracted to a sodium atom that has an extra electron making it negative. Together they are neutral and that bond is called ionic because it is formed between two ions. Covalent bonding, like in water, happens because the oxygen and hydrogen atoms are able to share electrons so that their outermost electron shells are satisfied. Because oxygen has more protons than hydrogen, the electrons tend to congregate around the oxygen atom, making it slightly negative and the hydrogen atoms slightly positive, although together it is still neutral. The slightly positive hydrogen atoms are also attracted to neighboring negative oxygen atoms in other water molecules and this produces the hydrogen bonds you mentioned earlier. Does this fall under the heading of “I asked for this much and you gave me THIS MUCH?”
