The answer is "which istope of what element?" An isotope of an element is an atom of that element that has the correct number of protons (the "atomic number") which defines the element, and one of a variety of numbers of neutrons. The number of protons plus the number of neutrons in the atom determine the "Atomic Mass" of that isotope of that element. A "standard" atom of carbon, for example, has 6 protons and 6 neutrons, for an atomic mass of 12 (hence it is called carbon 12) Another isotope of carbon is carbon 14, which has 6 protons to define it as carbon, but has 8 neutrons. It is the same element, with the same chemical properties, but a slightly different mass.
The "standard" atom of fluorine has an atomic mass of 19 and an atomic number of 9. This is the only stable sotope of fluorine. Other isotopes can be made, but they decay very rapidly, splitting in to lighter elements and emitting energy as radiation.
What else can I help you with?
Is the sum of the numbers of protons and the number neutrons in an atom is the mass number?
It is the mass number for that particular form of the atom - that particular isotope. An element can exist as more than one isotope and the atom's mass number is the (weighted) average of the mass numbers of all its isotopes.
How is a fluorine isotope different from a fluorine ion how are they the same?
The fluorine isotope differs from the fluorine ion because the fluorine isotope has a different number of neutrons from normal, while the ion has a different number of electrons. An isotope will have the same number of electrons as its atomic number (the number of protons), while the ion will add (more common in the case of fluorine) or subtract (very rare in the case of fluorine) electrons to the atom. The only thing they are similar in is the number of protons they have, which are the same.
Would carbon or fluorine atom be more reactive?
A fluorine atom would be more reactive than a carbon atom because fluorine is more electronegative and has a stronger tendency to attract electrons. This means that fluorine is more likely to participate in chemical reactions to achieve a stable electron configuration.
An atom that has more neutrons than protons is called what?
An atom that has more neutrons than protons is called an Isotope.
What is one of two or more species of atom having an identical atomic number but differing in mass number called?
Isotope
How many protons electrons and neutrons are in the element fluorine?
The number of protons is the same as the atomic number, which is nine in this case. If the atom is neutral, then the number of electrons will balance the number of protons, also nine in this case. Usually, the number of neutrons will vary with the isotope (atoms with a different number of neutrons) however, fluorine has only one natural isotope, 18F, with nine neutrons.See link below for more information on fluorine, as well as the related question below that will show you how to find the number of each subatomic particle in any atom.
How do scienctist tell the difference between two isotope of the same element?
Isotopes of the same element are determined based off the number of neutrons the atom has which is directed related to the atomic mass of the element( the more neutrons the greater the mass of that atom). Because you can not change the number of protons in an atom without changing the element, scientist differentiate isotopes based off the atomic mass of the isotope.
The electrons in the bond between hydrogen and fluorine are more strongly attracted to which atom?
The electrons in the bond between hydrogen and fluorine are more strongly attracted to the fluorine atom. Fluorine has a higher electronegativity than hydrogen, meaning it has a stronger pull on the shared electrons in the bond.
Formula of atomic mass?
The atomic mass of an element is the weighted average of the masses of its isotopes, taking into account their natural abundance. It is calculated by multiplying the mass of each isotope by its abundance percentage, then summing these values to obtain the atomic mass. Mathematically, atomic mass = (isotope mass1 * %abundance1) + (isotope mass2 * %abundance2) + ...
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.
Which is more electonegative a fluorine atom or a calcium atom?
Fluorine is more electronegative than calcium. Electronegativity is a measure of an atom's ability to attract shared electrons in a chemical bond, and fluorine has a higher electronegativity value than calcium.
Is an atom with more protons than electrons an isotope?
No, it is not.
