Its mass number is 80.
Z=# of electrons=number of protons (unless it's an ion)
A=Z+# of neutrons
A=35+45=80

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 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.
An atom has an atomic number 17 and atomic mass number 35. How many neutrons are present in its nucleus?
36 The answer of this question is there are 30 protons and 35 neutrons
What is the number of neutrons in an atom with atomic mass of 35 and three energy levels and 7 valence electrons?
There are 18 neutrons. If the valence level has 7 electrons, that means the first is full, and always has 2(unless its hydrogen which has 1) and the second will be filled with 8 making 17 total. Since the electrons always equal protons we know there are 17 protons. Since atomic mass is protons plus neutrons, and atomic mass is 35 we minus 17 form 35 and have 18.
How many electrons belong to a neutral atom with an atomic mass of 36 amu?
A neutral atom with an atomic mass of 36 amu will have 36 electrons. This is because the atomic mass of an atom is determined by the sum of its protons and neutrons, and in a neutral atom, the number of electrons is equal to the number of protons.
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 electrons and neutrons in bromine-80?

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).
What is the protons neutrons and electrons for 65Zn?
Protons- 30 Electrons- 30 Neutrons- 35 Zn-65 means the atomic number plus the number of neutrons equals 65. Zinc always has 30 protons; therefore, it's atomic number is 30 and it has 30 protons and electrons. The remaining number is the neutrons: 65-30= 35
If the atomic mass of chlorine is 35 how many neutrons does it have?
The number of neutrons in chlorine is 18 (no of neutrons=atomic mass-no of protons=35-17=18)
How many neutrons does chlorine -35 have?
It has 18 neutrons. Its really simple, 35 is the mass number(A) i.e., the total number of neutrons and protons. We know atomic number(Z) of chlorine is 17. This is the number of protons. So A-Z will give us number of neutrons.
An atom has an atomic number 17 and atomic mass number 35. How many neutrons are present in its nucleus?
36 The answer of this question is there are 30 protons and 35 neutrons
Bromine has an atomic number of 35 and a mass of 80 why isn't Bromine's atomic number 70?
atomic number is based on the number of neutrons and electrons.
What is the number of electrons and neutrons for zinc?
Zinc common isotope is 65 atomic mass element number 30. So it has 30 protons, 30 electrons and 35 neutrons
An atom has 29 electrons and protons and 35 neutrons what is the mass number?
30 The atomic number is the number of protons
What is the number of neutrons in an atom with atomic mass of 35 and three energy levels and 7 valence electrons?
There are 18 neutrons. If the valence level has 7 electrons, that means the first is full, and always has 2(unless its hydrogen which has 1) and the second will be filled with 8 making 17 total. Since the electrons always equal protons we know there are 17 protons. Since atomic mass is protons plus neutrons, and atomic mass is 35 we minus 17 form 35 and have 18.
Chlorine has atomic number 17 and mass number 35?
The atomic number tells you that chlorine atoms have 17 protons. If you know the mass number and atomic number, you can use subtraction to determine the number of neutrons like this: mass number - atomic number = 35 - 17 = 18. A neutral atom has equal numbers of protons and electrons. I'm guessing this is a neutral chlorine-17 atom, so it also has 17 electrons. So, and atom of chlorine-17 has 17 protons, 17 electrons, and 18 neutrons.
