It means there are 35 protons and neutrons in the nucleus of an atom of that particular element or isotope.
Among non-radioactive elements, the Cl-35 isotope has this mass number, and all chlorine atoms have 17 protons each.
The proton number corresponds to the element bromine. The mass number is not one for an element but rather for the isotope bromine-71.
35.453 is the atomic mass of chlorine.There are two isotopes of chlorine.

Answer: 20 You have to subtract the atomic mass from the protons. So it's 35-15=20 15 is the number of protons. 35 is the atomic mass.
30, Total weight - neutron number. 60 - 35 = 30

19, because since you know sulfur has 16 protons because that's its atomic number. you do 35-16=19
2, why? Because there is a danish in your back pocket
Answer: 20 You have to subtract the atomic mass from the protons. So it's 35-15=20 15 is the number of protons. 35 is the atomic mass.
Protons - 35 Neutrons - 43 Atomic Number - 35 Electrons - 35
30, Total weight - neutron number. 60 - 35 = 30
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.
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).
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.
36 The answer of this question is there are 30 protons and 35 neutrons
30 The atomic number is the number of protons
The number of neutrons in chlorine is 18 (no of neutrons=atomic mass-no of protons=35-17=18)

The mass number indicates the number of protons AND neutrons in the nucleus. Since the number of neutrons can vary, so can the mass number. The different versions of elements based on the number of neutrons are called isotopes. Sulfur-35 has an atomic mass of 35. So, it has a total of 35 protons and neutrons in the nucleus. Since sulfur always has 16 protons, then the number of neutrons in this isotope is 19. (35 - 16 = 19)
The mass number of the element chlorine is 35.5. The mass number (nucleon number) of an isotope of an element tells us the sum of the number of neutrons and protons. It is a decimal because mass numbers of elements are averages, based on the different isotopic forms of the element and their relative abundance.
