life's hard. Fluorine makes things harder. Brush your teeth with it.
hydrogen. it makes it explode:)
There is 19g of fluorine. That makes 1 mole.
Yes. fluorine is most reactive among all halogens as it has the highest electronegativity. Also, Fluorine has an incomplete outer shell that is closer to the nucleus so it is easier to attract an electron; this also makes fluorine the most reactive.
Covalent
This affirmation is not correct.
Small amounts of fluorine is good for human teeth and is in many city water supplies.
Nitrogen and fluorine are both nonmetals so that makes the bond a covalent bond. It's not hard.
Fluorine's electronegativity is 3.98. The difference between two fluorine atoms is 0, so the bond between two fluorine atoms is nonpolar covalent.
The number of protons is equal to the atomic number. Fluorine's atomic number is 9, so Fluorine has 9 protons.
The thing that makes fluorine so reactive is its electronegativity.
Carbon, hydrogen and fluorine.
