What atomic number of F plus the number of Na equals the atomic number of thos element?
The atomic number of F is 9, Na is 11, so F (9) + Na (11) = 20. The element with an atomic number of 20 is calcium (Ca).
What is the atomic number of F plus the atomic number of Na what?
You think probable to sodium fluoride , NaF.
What atomic number of f plus the atomic number of Na equals the atomic number of what element?
Calcium=Ca=Atomic number 20 9+11=20
What is the atomic number of F plus the atomic number of An equals the atomic number of this elements?
There is no element whose symbol is An.
What pairs is listed in order from smaller radius to larger radius F F- or Na plus Na?
Na+ is smaller than Na.
What atomic number of F plus the number of Na equals the atomic number of thos element?
The atomic number of F is 9, Na is 11, so F (9) + Na (11) = 20. The element with an atomic number of 20 is calcium (Ca).
What the atomic number of F plus the atomic number of Na equals equals the atomic number of this element?
At No(F) + At No(Na) = 20.At No of Calcium = 20.
What is the atomic number of f plus the atomic number of Na equals the atomic number of this element?
The atomic number of F (fluorine) is 9 and the atomic number of Na (sodium) is 11. Adding them together gives 20, which is the atomic number of calcium (Ca).

What atomic number of f plus the atomic number of Na equals the atomic number of what element?
Calcium=Ca=Atomic number 20 9+11=20
What atomic number of F plus the atomic number of Na equals the atomic number of this element?
Calcium
What is the atomic number of F plus the atomic number of An equals the atomic number of this elements?
There is no element whose symbol is An.
What pairs is listed in order from smaller radius to larger radius F F- or Na plus Na?
Na+ is smaller than Na.
What is the atomic number for F?
The atomic number of a Fluorine (F) atom is 9, meaning it has 9 protons within its nucleus.
How to calculate the percent composition of F in NaF?
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.
