How many electrons are in a neutral atom of 19F?
A neutral atom of fluorine-19 (19F) has 9 protons and 9 electrons. This is because the number of protons determines the element's identity, so fluorine always has 9 protons, and in a neutral atom, the number of electrons is equal to the number of protons.
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.
What is the nuclear symbol for an element with 9 protons and 10 neutrons?
The nuclear symbol for an element with 9 protons and 10 neutrons is 19F. The atomic number (number of protons) is shown as a subscript to the left of the element symbol, and the mass number (sum of protons and neutrons) is shown as a superscript to the left of the element symbol.
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.
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.
What is the atomic number of 19F?
The atomic number of fluorine is 9.

What element has 19 mass number?
Fluorine (F), the isotope 19F.
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 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 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.
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 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 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.
