How many protons dose fluoride have?
Every fluoride ion contains 9 protons. The only common ion of fluorine has a single negative charge, indicating that it contains one more electron than proton, or 10 electrons. The number of neutrons is the mass number minus the atomic number (same as the number of protons). The most common isotope of fluorine is F-19, which contains 19 - 9 = 10 neutrons.
What atom has the mass number 9?
Elements are typically classified by the number of protons, since electron count can vary in ions. However, the element with 9 protons and 9 electrons (in the non-ionized configuration) is fluorine.
What is the charge on fluoride ion in the water?
Pure water is H2O chemically. There is no fluorine in it. However, in fluoride ions can be present as impurity and they have the formula F- with -1 charge on fluorine.
Can you use the number of electrons to find the atomic number?
The number of electrons are always equal to the number of protons to keep the atom's charge neutral (unless your dealing with ions). And the number of protons in an atom are it's atomic number. So essentially, the number of electrons is the atomic number.
What is the formula used to calculate the number of electrons when only the atomic number is given?
The number of electrons is simply the same as the atomic number, assuming the compound or element is neutral (not positive or negative). To find the number of neutrons, take the atomic mass and subtract atomic number. The number of electrons is simply the same as the atomic number, assuming the compound or element is neutral (not positive or negative). To find the number of neutrons, take the atomic mass and subtract atomic number.
What is the charge of fluorine ions in water?
Fluorine ions, called fluoride when ionised, have a single negative charge F-.

Does ion have neutral charge?
A positively-charged ion or cation has more protons than electrons. The proton number is the atomic number of the element, while the electron number is the atomic number minus the charge. A negatively-charged ion or anion has more electrons than protons . Again, the number of protons is the atomic number. Positive ions are chemical species which carries a positive electrical charge. These ions form when an atom or molecule loses an electron. Therefore, Positive ions have more protons than electrons. But, negative ions are chemical species which carries a negative electrical charge. These ions form when an atom or molecule gains an electron.
How do you find the atomic number in an atom?
What number of protons there are that's the atomic number. B/c the atomic number is the same as the number of protons. Electrons are usually of the same quantity, however in ions (an atom with a charge) they vary. this is what gives an atom a positive or negative charge.

What elements does not form an ion with a charge of 1 fluorine hydrogen potassium sodium?
All the listed elements form ions with a charge of 1, if "1" is taken as the absolute value of the charge on the ion. For fluorine, however, the corresponding ion has a charge of -1.

Why fluorine form negative ions?
The atomic number of fluorine is 9. Therefore its outermost shell contain 7 electrons and hence its valency (oxidation state) is -1.Hence fluorine will take part in chemical reactions by accepting 1 electron to complete its octet. So it forms negative ion F- .Added:Actually this is the only possible ion form of fluorine, being the most electronegative element of all. Positive ions are impossible.
What is the charge of two ions of fluorine F2?
Ions such as fluorine always have a Negative charge- when looking at the periodic table you will see groups 8,7,6,5,4 and 3 on the right side. All noble gases in Group 8 have no charge, but going to the left: 7 = -1 charge 6 = -2 charge 5 = -3 charge 4 = -4 charge This only works for nonmetals, not transition metals so be careful. So, looking at Fluorine it is in Group 7 7 Nonmetals always have a -1 charge. 2 Fluorine Ions * -1 = -2 -2 is your answer. When it meets with a positive ion (Groups 1 and 2 on the left side of the periodic table), the two charges will need to balance. So the positive ion will need to be +2. This can happen naturally (positive ions in Group 2 are +2, so 2F and 1Ca will work) or because there are enough positive ions to balance the charge (positive ions in Group 1 are +1, so having 2F and 2Na will work). Good luck :)
Do molecule have charge?
No. Molecules do not have charge. Ions have a charge. If a compound is has more than one atom and a charge, then it is a poly-atomic ion, not a molecule.
