1 mol of fluorine atoms (F) is 18,998 403 163(6) g.
The first ionization energy is 1681 kJ/mol.
NO, sure not. Helium (He) mass = 4 g/mol Fluorine gas (F2) mass = 2*19 = 38 g/mol (almost 10 times heavier), although fluorine gas hardly can be held stable: it is so VERY rective, even in air!!
The valency of fluorine is -1.
36 g water contain 32 g oxygen.32 g oxygen is equivalent to 1 mol oxygen.1 mol has 6,023.10e23 molecules (or atoms, ions).
fluorine oxidation number is -1
1 mole is itself, a quantity. But, if you like, the quantity is 6.022140857*10^23 atoms of fluorine.
Fluorine (F) has an atomic weight of 18.9984032 g/mol
The ionization energy of fluorine is 1681 kJ/mol (the first) and the ionization energy of iodine is 1008,4 kJ/mol.

it can be said that 1 mole oflithium is equal in mass to its molar mass wwhich is 6.94 g/mol
The formula is CaF2 so, its three atoms, one calcium and two fluorine atoms. add the molar mass of calcium(40 g/mol) and fluorine(19 g/mol X 2 because there are two atoms of fluorine) and you get 40+(19x2)=78 78 grams per mol
The first ionization energy is 1681 kJ/mol.
NO, sure not. Helium (He) mass = 4 g/mol Fluorine gas (F2) mass = 2*19 = 38 g/mol (almost 10 times heavier), although fluorine gas hardly can be held stable: it is so VERY rective, even in air!!

For LiCl: 408,6 kJ/mol. For AlCl3: 704,7 kJ/mol.
The valency of fluorine is -1.
3.2 mol XeF_7 * 7mol F/1mol XeF_7 = 22.4 mol F Easy as pie.
