A fluorine atom has 9 protons 10 neutrons and 8 electrons What are the mass number and atomic number for this atom?
Mass number = 19, Atomic number = 9
What is the symbol of fluorine atom including its mass number and atomic number?
Symbol - F Atomic Number - 9 Mass Number - 19
What is the mass number of elemen f?
Atomic number of Fluorine is 9.Mass number of Fluorine is 19.
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 has 9 protons; that's what the atomic number is, it tells you the number of protons in the nucleus.
What is the atomic number of an element whose atoms have 9 protons and 10 neutrons?
The atomic number is the number of protons. It is also the number of electrons. The atomic mass equals the protons and neutrons together/weight of the nucleus. So, the atomic number would be nine, because there are 9 protons. The atomic mass would be around 19, because there would be 9 protons and 10 neutrons in the nucleus. The element you are talking about is actually Fluorine, and on the periodic table it says that the atomic mass is 18.9984032. This is because the atomic mass is usually never an exact amount. You can round this decimal place to 19, anyway.
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?
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?
What is symbol atomic number atomic mass of fluorine?
According to the periodic table: F atomic number 9, atomic mass of 18.998403
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 the mass number of F?
Atomic number of Fluorine is 9.Mass number of Fluorine is 19.
A fluorine atom has 9 protons 10 neutrons and 8 electrons What are the mass number and atomic number for this atom?
Mass number = 19, Atomic number = 9
What is the symbol of fluorine atom including its mass number and atomic number?
Symbol - F Atomic Number - 9 Mass Number - 19
What is the mass number of elemen f?
Atomic number of Fluorine is 9.Mass number of Fluorine is 19.
Atomic number for fluorine?
Symbol: F Atomic Number:9 Atomic mass: 18.998 Mass Number: 19 Number of Protrons: 9 Number of Electrons: 9 Number of Neutrons: 10
Which element has an atomic number of 19?
Fluorine is a non metal element. Atomic mass number of it is 19.
An atom with an atomic number of 9 and a mass number of 19 would have an atomic mass of what?
The atomic number of the potassium is 19. So the number of protons and electrons is 19 in the atom of potassium. The number of neutrons can be calculated as mass number minus atomic number. It comes to be 39 minus 19. That is 20.
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.
An isotope of fluorine has a mass number of 19 and an atomic number of 9. how many protons are in this atom?
9
