Ionic. Na+ and F-
The cation,Na +and the anion,F -form the ionicly bonded compound,sodium fluoride.
No. F-1 is just an ion. If it is put together with some positive ion, it can then form an ionic bond.
F has one extra electron, which will goes in outer layer making F bigger. Na has one less electron, which will cause its size to get smaller.
Na + Br ₂→ NaBr This happens because: When certain diatomic elements (Br, I, N, Cl, H, O, F) are alone you add a 2 as a subscript so they are (Br₂, I,₂ N₂, Cl₂, H₂, O₂, F₂). But when you cross Na (which has a charge of +1) with Br (which has a charge of -1) They cancel and you get NaBr.

Sodium- Na Fluorine- F Together- NaF
It turns purple!!
Ionic. Na+ and F-
Depending on the word, you misspell it.
Na+ is smaller than Na.
The average temperature of soda is 66 F. This happens when you put it in ice, water, and salt.The average temperature of soda is 66 F. This happens when you put it in ice, water, and salt.

To find percent composition, you must work with the atomic masses. Look on a periodic chart to find the atomic masses of F and Na. You will find that Na has an atomic mass of 22.990 grams per mole of Na and that F has an atomic mass of 18.998 grams per mole of F. So, add these both together, and that will tell you how much mass NaF will be. NaF will have a mass of 41.988 grams per mole of NaF. Now to take the percent composition of F in NaF, simply divide the mass of F by the mass of NaF. That will give you [18.998/41.988]=.452 which will be about 45%. So your answer is that F has a 45% composition of NaF. PS: Since Na and F only had a stoichiometry of 1 (meaning there is 1 Na and 1 F in the molecule), no multiplication of the atomic masses was necessary when calculating the total mass of the molecule.
No. F-1 is just an ion. If it is put together with some positive ion, it can then form an ionic bond.
In NaF, there exists Na+ and F- ions and with the electron configuration of [He]2s22p6 (for Na+) and [He]2s22p6 (for F-)
At No(F) + At No(Na) = 20.At No of Calcium = 20.
