What information can you gather knowing the atomic number and mass of an element?

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.


What number represents the number of protons in an atom?

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.


How you can use an atomss mass number and atomic number to determine the number of protons electrons and neutrons in the atom?

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.


How many neutrons protons and electrons in fluorine?

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


What represents the number of protons and neutrons in an atom of uranium?

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).

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 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.


What can be determined by looking at the atomic number of an element?

the number of protons in an atom and the number of electrons in an atom


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!


How many protons neutrons electrons atomic number and atomic mass does bromine have?

Protons - 35 Neutrons - 43 Atomic Number - 35 Electrons - 35


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.


What is the number of protons in the necleus?

# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass


How many protons neutrons and electrons are in beriyllium?

Berilyllium 'Be' has 4 protons and electrons (atomic number), it has 5 neutrons (mass number minus atomic number) :)


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.


Protons electrons and neutrons in any given atom?

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)


LList the number of protons electrons and neutrons in americium?

Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons.
