For young students, let's assume that all elements of bromine have a molecular weight of 80. Because electrons have effectively no mass, what the molecular weight is is basically the number of protons plus the number of neutrons. So the number of neutrons = 80 - 35 = 45.
For older students, bromine has two isotopes, 79Br and 81Br. So, for the former isotope bromine would have 44 neutrons, and for the latter isotope it would have 46 neutrons. The natural abundance of each isotope is approx 50%.
Bromine has the atomic number 35, which means there are 35 protons in the nucleus of an atom of bromine.
The mass number (also known as the atomic mass number) of an element is the sum of the protons and neutrons in the nucleus.
Bromine's mass number is 80, so there must be 35 protons and 45 neutrons in an atom of bromine.
What else can I help you with?
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.
35 protons how many electrons?
An atom with 35 protons is iodine, which is a neutral atom. In a neutral atom, the number of electrons equals the number of protons, so it also has 35 electrons. Therefore, an atom with 35 protons has 35 electrons.
What is Br number of protons?
Br-80 has 35 protons.
What Nonmetal halogen family atomic mass unit 35?
Chlorine is the non metal halogen family atomic mass.... 35
How many protons are in br-80?
There are 35 protons in bromine-80 (Br-80). This is because bromine has an atomic number of 35, which corresponds to the number of protons in its nucleus.
How many does protons does fluorine?
Fluorine is a halogen gas. It has 19 protons in a single atom.
How many protons and electrons in ion Br?

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.

35 protons how many electrons?
An atom with 35 protons is iodine, which is a neutral atom. In a neutral atom, the number of electrons equals the number of protons, so it also has 35 electrons. Therefore, an atom with 35 protons has 35 electrons.
What is Br number of protons?
Br-80 has 35 protons.
What Nonmetal halogen family atomic mass unit 35?
Chlorine is the non metal halogen family atomic mass.... 35
How much protons is in bromine?
35 protons
What non metal has the most protons in the halogen group?
Radon (86). And all the halogens are "non metals".
How many protons are in br-80?
There are 35 protons in bromine-80 (Br-80). This is because bromine has an atomic number of 35, which corresponds to the number of protons in its nucleus.
What is a nonmetal in the halogen family with an atomic mass of 35?
Bromine is the element with atomic number 35.
What is the number of protons neutrons and electrons in the neutral atom bromine-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.
What is only an element in the halide family that is a liquid?
Bromine Br Atomic number 35. Number of protons-35 Neutrons-45. Electrons-35
