It means there are 35 protons and neutrons in the nucleus of an atom of that particular element or isotope.
An atom with a mass number of 65 and 35 neutrons would have 30 protons. This is because the mass number is the total number of protons and neutrons in the nucleus, and the number of neutrons is subtracted from this to find the number of protons.
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.
The mass number of an element is the sum of its protons and neutrons. Since Bromine has 35 protons (atomic number) and 45 neutrons, its mass number would be 35 + 45 = 80.
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.
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.
Protons - 35 Neutrons - 43 Atomic Number - 35 Electrons - 35

30 The atomic number is 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).
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.
The mass number of an element is the sum of its protons and neutrons. Since Bromine has 35 protons (atomic number) and 45 neutrons, its mass number would be 35 + 45 = 80.
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.
The mass number is the amount of protons and neutrons in an element. The atomic number is equal to the amount of protons. Therefore to get the number of protons from the given information, you would subtract 37 from 72 which gives you 35 protons aka its atomic number!
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.
A bromine atom, regardless of its mass number, has an atomic number of 35, which means it has 35 protons and, in a neutral state, also 35 electrons. Therefore, a bromine atom with a mass number of 87 will have 35 electrons. The mass number indicates the total number of protons and neutrons, but it does not affect the number of electrons in a neutral atom.
the atomic number would be 17 && the mass would be 35
