What is the Mass number of a bromine atom?
Bromine has an approximate atomic mass of 79.904.
What is the atomic number and mass number of bromine?
Bromine is a non meta element. Atomic mass of it is 80.
What is the mass number of Br-79?
Bromine is a non metal element. Atomic mass of it is 80.
How many protons and neutrons are in the nucleus of a bromine atom?
There are 35 protons and 35 electrons in the elementary Bromine, BrThe number of neutrons however depends on the isotope mass number of Bromine:There are two stable natural occurring isotopes Br-79(50.5%) and Br-81 (49.5%)To know the number of neutrons one should substract the atom number (35) from the mass number and you'll find the number of neutrons being 44 and 46, because 35 protons with 44 (or 46) neutrons gives you the mass number 79 (or 81)

What is Bromine atomic mass?
Bromine is a metal element. Atomic mass of it is 79.90.
What is the relative atomic mass of bromine?
Bromine is a non meta element. Atomic mass of it is 80.
How do you find the protons and neutrons in bromine?
To find the protons in Bromine, atoms always have the same number of protons as their atomic number, so since Bromine has an atomic number of 35, it has 35 protons. To find the average number of neutrons in Bromine, you take the the atomic mass and take away the number of protons (in this case 35), so since Bromine's atomic mass is 79.90, you take away 35 to get the number of neutrons. The average number of neutrons in Bromine is 44.90.
What has the lowest atomic number of any metal?
Bromine, because Bromine has an atomic mass of only 5.
