If you asking what it is, it is potassium.
This chemical element is fluorine.
The symbol of a fluorine atom is F. It has an atomic number of 9 and a mass number 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).
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.
Atomic number of Fluorine is 9.Mass number of Fluorine is 19.
Fluorine has an atomic number of 9, which means it normally has 9 protons. With a mass number of 19, the total number of protons and neutrons in fluorine is 19. Therefore, subtracting the atomic number of 9 protons gives us 10 neutrons in fluorine with a mass number of 19.
If Element B Has 9 As The Atomic Number And 19 As The Mass Number What is The Answer how many protons does it have?
According to the periodic table: F atomic number 9, atomic mass of 18.998403
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.
Atomic number of Fluorine is 9.Mass number of Fluorine is 19.
The symbol of a fluorine atom is F. It has an atomic number of 9 and a mass number of 19.
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.
Symbol: F Atomic Number:9 Atomic mass: 18.998 Mass Number: 19 Number of Protrons: 9 Number of Electrons: 9 Number of Neutrons: 10
Atomic number of Fluorine is 9.Mass number of Fluorine is 19.
Fluorine is a non metal element. Atomic mass number of it is 19.
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).
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.
