If an atom has 35 electrons and its mass number is 80 calculate the number of protons?
In a neutral atom, the number of electrons will be the same as the number of protons. This is because one positive proton will cancel out one negative electron; therefore, if the atom is neutral, it must have the same number of protons and electrons.The number of protons is also the same as the atomic number. For this example, Bromine, with the atomic number of 35, has 35 protons.Bromine:Atomic number- 35Number of protons- 35Number of electrons- 35The mass number is the sum of the atomic number (or number of protons/electrons) and the neutrons. For this example, we know the atomic number (35) + # neutrons = mass number (80). To figure out the number of neutrons, take the mass number and subtract the number of electrons/protons/atomic number. Mass number (80) - atomic number (35) = neutrons (45).

How many protons electrons and neutrons does an atom with atomic number 20 and a mass number 45 contain?
Atomic number 20 therefore 20 protons and 20 electrons. Mass number 45 therefore 45-20 = 25 neutrons.
If an element has an atomic number of 45 and an atomic mass of 92 the number of protons it has is?
The atomic number always gives the number of protons or electrons. The neutrons are obtained by subtracting the number of protons from the atomic mass. In this example, since 45 is the atomic number, this element has 45 protons. since the mass is 92, the number of neutrons is 92-45= 47. However, this is not really true because the element with 45 as atomic number is rhodium and it has a mass of 103 u and hence a total of 58 neutrons.
How many protons are in the isotope element Th?
Thorium (Th) has 90 protons.
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.
