whats inbetween atoms? is it some sort of force? is this force the reason for black holes? if a star gets so heavy that this force just isn't strong enough anymore to create this space inbetween the atoms, does this create black holes?

[Anonymous No.1658097]

You're kinda right. Read up on the nuclear forces, it's really interesting,

[Anonymous No.1658114]

Never heard of a vacuum before? That's the name for a space with essentially nothing in it with the exception of hypothesized dark matter. You'll also find a couple of hydrogen atoms and ions floating around in a vacuum, not many at all though.

Yes there's a force between atoms, it's called the electric force and can be calculated by using Coulomb's law. It's what holds molecules and pretty much everything at our Earthly scale together. At much larger scales, gravity is the force responsible for holding objects of astronomical size togther, and at a much smaller scale, the nucleas of an atom is held together by nuclear forces.

>force holding atoms together
>electric force

The stupid, it hurts.

[Anonymous No.1658135]

The space between atoms is empty space. The reason there is space between the atoms is the Pauli exclusion principle. When that isn't strong enough to overcome gravity anymore, then yeah you get neutron stars and black holes.

bitches don't know about my STRONG force.

intermolecular forces are essentially electrical forces

Hold on, I wasn't talking about a single atoms. I meant more than one atom, I was talking about intermolecular and intramolecular forces, and van der waals forces.

[Anonymous No.1658151]

>>1658132

Well, it ain't gravity, weak, or strong forces.

[Anonymous No.1658159]

>>1658149
oh, then yeah molecular bonds hold them together if they form molecules.

can't you just wikipedia it?

[Anonymous No.1658165]

What I don't get is:

quarks are points
electrons are points

Every fundamental particle is a infinitely small point.

How can anything have any volume at all?

[Anonymous No.1658169]

>>1658159
>molecular bonds
What force do you think is responsable for molecular bonds? It's an electric force

[Anonymous No.1658173]

>>1658165
Magic, yo

also electrons and other subatomic particles are not points, they do have a size. not that that has anything to do with why anything has volume.

Infinitely small quantities can in fact add up to become a significant amount. See http://en.wikipedia.org/wiki/Zeno's_paradoxes

[Anonymous No.1658185]

>>1658169
if it's an ionic bond, then yeah

otherwise no

[Anonymous No.1658186]

>>1658165
cause there's a shitload of it. Note it's infinitesimally small, not without . A bunch of .000001s added together will eventually make a billion.

[Anonymous No.1658193]

>>1658185

Alright then, which of the other three forces is responsible for covalent bonds?

[Anonymous No.1658201]

>>1658165

>How can anything have any volume at all?

The space between an atom's nucleus and its outermost atomic orbital represents its volume. It's a hell of a lot more than just the nucleus itself, and most of it is either filled with electrons or is empty space.

[Anonymous No.1658199]

OP, what happens in stars is largely dictated by their mass.

The Chandrasekhar Limit (1.44 solar masses) describes the upper bound of mass in which stars can be supported by electron degenerate matter (where electrons are forced to their ground state and cannot occupy any higher energy level). Stars of this mass or less usually end up as white dwarfs.

The Oppenheimer-Volkoff Limit (1.5-3 Solar Masses), like the Chandrasekhar Limit, describes the mass range in which stars can be supported by neutron degenerate matter.

Anything above these limits usually results in the collapse of the star not being able to keep up with its outward expansion, resulting in a black hole.

>and most of it is either filled with electrons or is empty space.
Yes and no.. 99.9% of an atom's volume is empty space.

[Anonymous No.1658231]

>>1658225

Hence the "either."

>they still think only forces cause things to happen!

please, draw the force vector for a pi bond between two atoms.

[Anonymous No.1658248]

>>1658199
whoops, got that the other way around. A black hole results when the outward expansion due to internal pressure, can't match that of the collapse due to its own gravity.

In b4 aether

[Anonymous No.1658273]

There are countless black and whiteholes everywhere. They determine the shape of strings.

[Anonymous No.1658308]

>>1658244

give me something that happens witch didn't take energy/force to happen.

[Anonymous No.1658361]

>>1658308
force is simply the derivative of energy with respect to space

[Anonymous No.1658430]

>>1658308
well, the pi bond for one. although now you're bringing energy into this when you didn't before, nice dodge.

here's my counter: this shit be quantum yo, all electron orbitals are and you just have to deal with it. Stop living in such a Newtonian world.

No. I'm a mechanical engineer major, I live in a world where everything can be drawn on a freebody diagram.

you're not the guy I was arguing with, right? you seem to have a better grasp of basic English.

anyway good for you, i'm biomedical engineering myself but since I'm finishing up my ochem courses i'm just trying to set the record straight.

>you're not the guy I was arguing with, right?
Correct, I can't say much about pi and sigma bonding I'm afraid, I only have a basic knowledge about it.
