Only protons and neutrons have 1 unit mass each, which form the nucleus. The Electrons that orbit the nucleus are of negligable mass. Therefore; total mass = 9 protons + 10 neutrons = 19 unit mass.
The element described is fluorine. The reason that it is fluorine is because it has 9 protons, which defines the element, and which is its atomic number on the Periodic Table. Every element has its own unique number of protons which is its atomic number.
This is an Oxygen-17 isotope.
Isotopic mass = 16.9991315 u. (Approximately equal to no. of protons + no. of neutrons = 8 +9 = 17)
What type of atom or ion would have 8 protons 9 neutrons and 10 electrons?
9: The atomic number of an element or an atom of the element is always the same as the number of protons in the nucleus of an atom of the element.
mass number = number of protons + number of neutrons = 8 + 9 = 17
so mass will be 17 amu
The atom is Flourine
Mass Number = no. of nucleons in the atom = no. of protons + no. of neutrons
A = 9 + 10 = 19
Such a particle would be a fluoride ion.
If you know the atomic no. and atomic mass, then the no. of electrons, no. of protons and no. of neutrons can also be determined. Atomic No.=No. of electrons = No. of protons. No. of neutrons=Atomic mass-Atomic no. Also, by no. of electrons you can determine its valency and the no. of valence electrons.
Protons are represented by the atomic number of an element. The number of protons is also the number of electrons. The number of protons is also represented in re Atomic Mass, which is the number of protons and the number of neutrons combined.
number of protons and electrons present in an element is equal to the atomic number of that element while number of neutrons is equal to mass number - atomic number/number of protons/number of electrons.
The atomic number of fluorine is 9. So it has 9 protons and 9 electrons. Number of neutrons depends on the isotope. Number of neutrons = Mass number - Atomic number F-19 has 10 neutrons
The number of protons is equal to the number of electrons and the atomic number. The number of neutrons is different for each isotope (number of neutrons = atomic mass of the isotope [or mass number] - number of protons).
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.
the number of protons in an atom and the number of electrons in an atom
No. of protons=No. of electrons = Atomic number. No. of protons + No. of neutrons = Atomic mass.
Protons - 35 Neutrons - 43 Atomic Number - 35 Electrons - 35
Nitrogen-14: 7 Protons, 7 Electrons, 7 Neutrons To work this out in the future for other elements: Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number Hope this helps!
# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass
Berilyllium 'Be' has 4 protons and electrons (atomic number), it has 5 neutrons (mass number minus atomic number) :)
79? I'm pretty sure the atomic mass of Bromine is 80. Incase you were wrong, the Atomic mass = Number of protons + Neutrons, which is 80. The atomic number is 35, which is the number of protons. Protons = 35. So the No. of Neutrons = 80 ( protons & neutrons) - 35 (protons) = 45 ( No. of neutrons) and Finally for electrons = the number of protons which is 35.
The atomic number of a chemical element is equal to the number of electrons or protons. The number of neutrons = Atomic weight of an isotope (rounded) - atomic number of the element (or the number of protons)
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons.
Americium has 95 protons and electrons. Number of neutrons: Atomic Mass of an isotope - number of protons
