An atom with an atomic number of 9 and a mass number of 19 would have an atomic mass of what?

To find the atomic mass, subtract the atomic number (protons) from the mass number (protons + neutrons). Atomic mass = Mass number - Atomic number Atomic mass = 19 - 9 Atomic mass = 10amu So, an atom with an atomic number of 9 and a mass number of 19 would have an atomic mass of 10 atomic mass units (amu).

How many neutrons does F-19 have?

The atomic number of Florine is 9 so it has 9 Protons in its nucleus. As the mass number of an atom is essentially the mass of the nucleus and as the mass of each Proton or Neutron is 1 this means that if there are 9 Protons there must be 10 Neutrons present to make up a mass number of 19.


Fluorine's atomic number is 9 and its atomic mass is 19. How many neutrons does fluorine have?

Answer is in the question itself. 19. Because atomic mass is nearly equal to the mass number of the atom. Mass number is always a round number that is natural number. The proton code for fluorine atom is 9. Mass number is the total number of protons and neutrons. So for mass number 19, the number of neutrons will be 19 - 9 = 10.


What is symbol atomic number atomic mass of fluorine?

According to the periodic table: F atomic number 9, atomic mass of 18.998403


How many protons are represented in an atom which has an atomic number of 9 and an atomis mass of 19?

An atom with an atomic number of 9 means it has 9 protons. The atomic mass of 19 indicates the total number of protons and neutrons in the nucleus, so if the atom has 9 protons, the remaining mass comes from neutrons (19-9=10 neutrons).


What is the mass number of F?

Atomic number of Fluorine is 9.Mass number of Fluorine is 19.


How many protons neutrons electrons in atom of fluorine?

An atom of Fluorine has the atomic number 9 and the mass number 19 (rounded up). This means it has 9 electrons, 9 protons and (19-9) 10 neutrons. The proton and electron count are taken from the atomic number. The mass number - the atomic number gives the number of neutrons.


Which element has an atomic number of 19?

Fluorine is a non metal element. Atomic mass number of it is 19.


A fluorine atom has 9 protons 10 neutrons and 8 electrons What are the mass number and atomic number for this atom?

The mass number is the sum of protons and neutrons, so it would be 9 (protons) + 10 (neutrons) = 19. The atomic number corresponds to the number of protons, which is 9 in this case.


If fluorine has an atomic number of 9 and an atomic mass of 19 how many electrons does fluorine contain?

The number of electrons is always the same as the atomic number. That gives you the number of protons and electrons. The atomic mass has nothing to do with it. What is the atomic number? That is your answer.
