How many protons does fluorine-19 have?

How many protons does fluorine-19 have?

9 protons
For example, a fluorine atom has 9 protons and 10 neutrons. Its atomic number is 9, while its atomic mass is 19 atomic mass units. So we can say that its atomic weight is 19, or its mass number is 19.

How many electrons does 19 have?

So if you look for potassium (symbol K in the periodic table), you will find that it has the atomic number of 19. This tells you that potassium has 19 protons and – since the number of protons is the same as the number of electrons- also 19 electrons.

How many protons electrons and neutrons are in F 19?

1 Answer. This isotope of fluorine has 9 protons, 9 electrons and 10 neutrons.

What is fluorine-19 mass number?

ChEBI ID. CHEBI:36940. Definition. The stable isotope of fluorine with relative atomic mass 18.998403 and nuclear spin 1/2.

What does the number 19 represent in fluorine?

Fluorine-19 is composed of 9 protons, 10 neutrons, and 9 electrons.

How many electrons does fluorine 18 have?

Fluorine-18 is composed of 9 protons, 9 neutrons, and 9 electrons.

What is fluorine 19 mass number?

How many neutrons are present in fluorine with a mass number of 19?

Why is fluorine-19 atomic mass?

The nucleus of a fluorine-19 atom contains nine protons because it has an atomic number of nine. As far as determining the number of neutrons for fluorine-19, we can use the mass number equation by substituting the number 19 for the mass number and the number nine for the number of protons.

What is the electronic configuration of 19?

The electronic configuration of the element with Atomic number 19 is 2,8,8,1 or 1s22s22p63s23p64s1 or [Ar]4s1.
