Its mass number is 80.
Z=# of electrons=number of protons (unless it's an ion)
A=Z+# of neutrons
A=35+45=80
Protons - 35 Neutrons - 43 Atomic Number - 35 Electrons - 35
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 isotope with 35 neutrons and a charge of 2+ means it has 33 electrons (atomic number - charge). The atomic number can be calculated by subtracting the number of neutrons (mass number) from the relative atomic mass, so in this case, the atomic number is 30 (65 - 35).
In an atom of chlorine with an atomic number of 17, the number of protons in the nucleus is 17. Since the atom is neutral, it will also have 17 electrons. Neutrons can be calculated by subtracting the atomic number from the atomic mass, so for chlorine with an atomic mass of 35, it would have 35 - 17 = 18 neutrons in the nucleus.
36 The answer of this question is there are 30 protons and 35 neutrons
Protons - 35 Neutrons - 43 Atomic Number - 35 Electrons - 35
Bromine has the atomic number 35, so it has 35 protons. To find the number of neutrons in Bromine-80, subtract the atomic number from the atomic mass: 80 (atomic mass) - 35 (protons) = 45 neutrons. Since it is a neutral atom, the number of protons and electrons are the same, so there are 35 electrons.

The element with atomic number 35 is bromine (Br). It has 35 protons and since it is neutral, it also has 35 electrons. To find the number of neutrons, subtract the atomic number (35) from the atomic mass (80). So, bromine-80 has 45 neutrons.

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).
An atom of bromine-81 has 35 protons, 35 electrons, and 46 neutrons. This is because the atomic number of bromine is 35, which corresponds to the number of protons and electrons, and the atomic mass of bromine-81 is 81, which is the sum of protons and neutrons.
The Bromine atom contains: 35 protons, 35 electrons, and 45 neutrons.
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.
In an atom of chlorine with an atomic number of 17, the number of protons in the nucleus is 17. Since the atom is neutral, it will also have 17 electrons. Neutrons can be calculated by subtracting the atomic number from the atomic mass, so for chlorine with an atomic mass of 35, it would have 35 - 17 = 18 neutrons in the nucleus.
The number of neutrons in chlorine is 18 (no of neutrons=atomic mass-no of protons=35-17=18)
36 The answer of this question is there are 30 protons and 35 neutrons
