How many neutrons protons and electrons does fluorine have?
The atomic number of fluorine is 9. Atomic number = amount of protons, as well as the amount of electrons in an uncharged atom. Neutrons is simply atomic mass - atomic number, so 19 - 9. (all information found on periodic table). So, 9 protons, 9 electrons, 10 neutrons.
The number of protons determines the?
Atomic number. For example, Hydrogen has 1 proton, and has an atomic number of 1. Helium has 2 protons, and has number 2. Neon has 10 protons and has number 10.
How many electrons are in a neutral atom of 19F?
All the information is there.The 9 is the atomic number of the atom, an element by definition has only 1 possible atomic number. This means it has 9 protons in the nucleus, and if it is atomic (not ionic), as it is in this case, then it has 9 electrons as well.19 refers to the atomic mass, this is the number of protons + the number of neutrons. So if we take the number of protons (9) away from the mass of the nucleus (19) we are left with 10, which must be the number of neutrons in this isotope of the element.To recap9 protons9 electrons10 neutrons
What is equal to the number of protons in an element?
The atomic number in an element is equal to the number of protons in an element. For example, Hydrogen has an atomic number of 1 and 1 proton.
How do you know how many protons an atom has by looking at a picture of it?
The number of protons in an element is the same as its atomic number. Hydrogen (atomic number 1) has 1 proton. Gold (79) has 79 protons, and so on. The number of neutrons is the same as its atomic number.

What element has 19 mass number?
Fluorine (F), the isotope 19F.
How many protons are in KBr?
Potassium (K) has 19 protons. The atomic number of an element is the same as the number of protons it has.

Protons are the same as the mass or the atomic?
The atomic number is the number of protons. For example, the atomic number of Hydrogen is 1, because it has 1 proton. The mass is calculated using protons, neutrons, and electrons.
How are the number of protons in an element determined?
Well... the element number defines the number of protons, and usually the electrons. the neutrons are determined with... i dunno :P I.E. hydrogen is 1. Therefor, in hydrogen there are 1 protons and 1 electrons.
How can you determine the number of protons in an atom changes?
For the alpha decay the number of protons decrease with 4; for the beta minus decay the number of protons ih higher with 1.

How is an atoms atomic number related to it's number of protons to electrons?
The atomic number of an atom is the number of protons in the nucleus of that atom. The number of electrons will equal the number of protons in that atom if that atom is a neutral one. Other than that, we would have to know the atomic number (which is the number of protons that atom has), and the overall charge of the atom. With that information, we could discover how many electrons that atom had by simple mathematics. If an atom had 11 protons and a charge of +1, it would have one less electron than the number of protons, or 10 electrons. If an atom had 53 protons and a charge of -1, it would have 54 electrons. The ratio from atomic number to the number of protons in an atom is 1:1. The elements are categorized by the number of protons they have, as that is the difference between two elements. Conceptually, atomic number and proton number are the same.
