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.

The atomic mass is equal to the sum of?
The Atomic Mass number of an element is the sum of the protons and neutrons in the nucleus of an atom of that element.The relative atomic mass is the average atomic mass number of all the known isotopes of an element.
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 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
What is the number of protons neutrons and electrons of radon?
There are 88 protons/electrons in radium. There are 138 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
How do you calculate the number of protons neutrons and electrons of an atom?
The charge of an ion can be calculated by adding up the protons and subtracting the electrons. When oxygen with 8 protons has 8 electrons it is neutral, when it has 7 electrons it is positively charged.
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.
What is the number of neutrons electrons and protons in nitrogen14?
there are 7 neutrons, 7 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

Determine the numbers of electrons protons neutrons 80 35 Br?
Number of Protons: 35 Number of Neutrons:45 Number of Electrons:35
How many electrons protons and neutrons are in uranium?
Uranium isotopes have 92 protons and electrons; the number of neutrons is different for each isotope.Number of neutrons = Mass number - Number of protons
What is neons number of protons electrons neutrons?
Protons: 10 Electrons:10 and Neutrons: 10.
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.
How many protons electrons and neutrons does an atom have?
Americium has 95 protons and electrons. Number of neutrons: Atomic Mass of an isotope - number of protons
What are the Number of protons neutrons and number of electrons found in an atom of neon?
Neutrons = 10. Protons = 10. And electrons = 10.
