Atomic Mass = protons + neutronsprotons = atomic mass - neutrons = 18 - 8 = 10 protons (Neon)
In ground state, protons = electrons = no charge
-1 charge means gain of 1 e-, so number of electrons = 11 electrons

How many protons neutrons electrons atomic number and atomic mass does bromine have?
Protons - 35 Neutrons - 43 Atomic Number - 35 Electrons - 35
How many protons and neutrons in the fluorine?
Fluorine has an atomic number of 9. Therefore it has 9 protons and electrons. It has an atomic mass of 19 amu. Therefore, the number of neutrons present can be calculated by subtracting the number of protons from its mass, i.e., 19-9=10. thus, fluorine has 9 protons and 10 electrons.
Which atomic particles have negative elecric charge neutrons protons or electrons?
Electrons have negative charge. They are present outside the nucleus.
How do you get the atomic number and weight?
No. of protons=No. of electrons = Atomic number. No. of protons + No. of neutrons = Atomic mass.
How many protons electrons and neutrons in bromine-80?
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.
How do you determine the number of protons electrons and neutrons present in an element by identifying its atomic and mass numbers from the periodic table?
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.
How do you find an atomic mass?
It is nothing but the total no of protons and electrons .So it is found by summing the total no protons and electrons present in an atom It is not electrons but the total of neutrons and protons present in the nucleus of any atom.
What are the number of protons neutrons and electrons in an element?
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
How many protons neutrons and electrons are found in phosphorous?
Phosphorus has an atomic no. of 15 and its atomic mass is 31.=we know,atomic no.=number of protons==also, atomic mass=no.of protons+no. of neutrons==this implies, 31=15+no. of neutrons= 31-15=no. of neutrons= 16=no. of neutrons==also,no. of protons=no, of electrons=so, total no. of protons=15total no. of electrons=15total no. of neutrons=16
Atomic particles located in the nucleus?
Neutrons and protons.
What is the number of protons in the necleus?
# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass
How many protons neutrons electrons atomic number and atomic mass does bromine have?
Protons - 35 Neutrons - 43 Atomic Number - 35 Electrons - 35
Where are protons neutrons and electrons located?
Protons, neutrons and electrons are located in the atom. The protons and neutrons are located in the atomic nucleus; the electrons are around the nucleus, arranged in shells.
How are protons and neutrons related?
For a stable atom, no. of protons= no. of electrons no of neutrons= Atomic Mass- no. of protons
How many protons and neutrons in the fluorine?
Fluorine has an atomic number of 9. Therefore it has 9 protons and electrons. It has an atomic mass of 19 amu. Therefore, the number of neutrons present can be calculated by subtracting the number of protons from its mass, i.e., 19-9=10. thus, fluorine has 9 protons and 10 electrons.
Which atomic particles have negative elecric charge neutrons protons or electrons?
Electrons have negative charge. They are present outside the nucleus.
What is the number of protons electrons and neutrons in n-14?
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!
