Atomic weight of fluorine = 6,022 141 78.1023 (Avogadro number) . 266,889 (the mass of atoms)/8,46.1024 (the number of atoms).
The IUPAC 2005 atomic weight of fluorine is 18,998 403 2(5).
The atomic weight (not mass) of fluorine is determined by mass spectrometry.
fluorine is a non metal element. Atomic number of it is 9.
it's density/phase is a gas. and it's atomic weight is 18.998403 and density is 0.001696
equal to number of protons
you take the atomic mass of the atom (or molecule) and you have the mass in grams
Atomic weights refer to ATOMS. Water is a MOLECULE made up of 3 atoms, it therefore does not have an atomic weight, it has a MOLECULAR weight.You calculate the molecular weight by adding up the atomic weight of all the atoms in the molecule.Waster is made up from 1 atom of Oxygen (atomic weight 16) and 2 atoms of Hydrogen (atomic weight 1)16+1+1 = 18The molecular weight of water is therefore 18.-------------------------------------------------------------------------------------The atomic mass of H is 1.008, and the atomic mass of O is 16.So 1.008*2+16=18.016
Fluorine (F) has an atomic weight of 18.9984032 g/mol
It is spelled 'Fluorine' The atomic weight is 18.9984032
fluorine is a non metal element. Atomic number of it is 9.
Neutrons have the same mass as a proton but lack an electrical charge. The number of neutrons can be found by subtracting the atomic number, or number of protons in the atom, from the atomic weight. This is calculated this way because the atomic weight represents both the number of protons and neutrons. Fluorine's atomic number is 9 and its atomic weight is 18.998, so 18.998-9= 9.998. Consequently, 9.998 is fluorine's number of neutrons.
Fluorine is the element with atomic weight closest to 19 amu. Fluorine has an atomic number of 9, so an electrically neutral fluorine atom would have 9 electrons.
This compound is UF6. Atomic weight of uranium: 238,02891 Atomic weight of fluorine: 18,9984032 Molecular mass of UF6: ca. 352,04121
Fluorine is a none metal element. atomic number of it is 9.
18.998 403 2(5)
In an uncharged atom, the number of electrons is always equal to the atomic number, in this instance, 9.
The atomic weight of an element is derived from the atomic masses of the isotopes of this element and from the percentage of these isotopes. The correct terms are: - atomic weight for elements - atomic mass for an isotope
There is no element called 'flouorine', however there is one called fluorine. What is it's atomic mass? It depends how accurate you want the answer, for most of us 19.0 is accurate enough. Mike Slater 19.0 is inappropriate, given that .0 is a significant figure and will be assumed to be correct. 19 would be more appropriate, and 18.998 would be more accurate.
The weight (mass) of an atom with 9 protons will vary depending on the number of neutrons. 9 protons defines the atom as fluorine (F), and it can have 10 protons, making the mass 19 amu, or it can have a mass of 14 amu up to 31 amu, but the only stable isotope is the one with a weight (atomic mass) of 19 amu.
