how does fluorine/flouride strengthen our teeth?

A box of cereal states that there is about .200mg of Calcium per serving of that cereal, how do I go about extracting that metal?

if there are neutron stars, can there be smaller stars which are made purely of electrons or protons?

shameless bump

>if there are neutron stars, can there be smaller stars which are made purely of electrons or protons?
no, because protons are all positively charged and electrons are all negatively charged and the electromagnetic force is much stronger than gravity; such a "star" would never even begin forming.

what if it had such a large mass, gravity compensated for this

idk, is the force of gravity stronger than the strong force?

large mass = more protons or electrons = repel even more

It doesn't. In fact, its poison, which is why I use baking soda.

>>1360662
then why is there fluoride in our teethpaste, claiming that it helps?

Read up what a neutron star is.

Big difference between flourine and fluoride, F2 and F-
Teeth have an emperical formula containing fluoride and calcium atoms and such, but believing theeth will absorb or even need more fluoride is in my opinion a load of crap. Teeth just wear down, they dissolve very slowly or something.

.200mg calcium in ceral isn't elemental calcium but Ca2+. You could try to precipitate it using sodium bicarbonate or something.
