Best Answer

To find out the number of electrons in an element you must add the protons and neutrons and subtract that number with the atomic mass, this will determine the amount of electrons because the unknown element could be an isotope and have more than the normal amount of electrons of the non isotope element.

No, you can't determine the number of electrons by adding protons and neutrons because electrons are not part of the nucleus of an atom. The number of electrons in a neutral atom is equal to the number of protons in the nucleus.

How would you calculate the atomic mass of atom without using the periodic table if you know the number of protons electrons and neutrons?

You can calculate the atomic mass by adding the number of protons and neutrons together, since electrons have a negligible mass compared to protons and neutrons. The sum of protons and neutrons will give you the atomic mass of the atom.


What are the number of protons neutrons and electrons in boron?

Boron has 5 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a boron isotope = Mass number - 5


Atomic masses of any two elements contain the same number of?

protons and neutrons. This is because the atomic mass of an element is calculated by adding the number of protons and neutrons in the nucleus of an atom. The number of protons determines the element's identity, while the number of neutrons affects its stability.


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.


What information does the atomic mass of an elemt provide?

the number of protons and neutrons in an atom. Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom. --> Atomic Mass = protons + neutrons

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


Do electrons equal the sum of the number of neutrons and protons in an isotope?

No. The number of neutrons has no affect on the number of protons and electrons.

How many protons electrons and neutrons does americium have?

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


How many protons neutrons and electrons in 40Ca plus 2?

40Ca has 20 protons and 20 neutrons. Adding 2 to the atomic number increases the number of protons to 22. Since the element is still Ca, it retains its 20 neutrons. Overall, the ion has 22 protons, 20 neutrons, and 22 electrons.


What is the number of protons neutrons and electrons of carbon 12?

Carbon-12 has 6 protons, 6 neutrons, and 6 electrons. The number of protons determines the element (carbon), the number of neutrons plus protons gives the mass number (12), and in a neutral atom, the number of electrons equals the number of protons.
