Bromine-79 has 44 neutrons and bromine-81 has 46 neutrons.
All the isotopes of bromine has 35 protons.
The element with 35 protons and 45 neutrons, for a total mass of 80, is Bromine (Br). The number of electrons should also correspond to the atomic number which is 35 in this case.
The nucleus is where all the mass of the atom is to be found and every nucleus is made of Protons and Neutrons which have about the same mass. Together these therefore give the atom its Mass Number. Thus if you know the Mass Number you know how many Protons and Neutrons the atom contains. If you are then told how many Neutrons there are, a simple subtraction of this number from the Mass Number will give you the number of Protons. The number of Protons in an atom defines what is called its "Atomic Number" and this is unique to each element. You can then look up the Atomic Number in a Periodic Table of the Elements and find out which element has that number.
Br-80 has 35 protons.
Number of protons + Number of neutrons = Mass number(number of nucleons)
Atoms having the same number of protons and neutrons make up the same element.
Bromine is a non metal element. Atomic mass of it is 80.
The element with 35 protons and 45 neutrons, for a total mass of 80, is Bromine (Br). The number of electrons should also correspond to the atomic number which is 35 in this case.

Br-80 has 35 protons.
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.
The element that has 8 protons and 8 neutrons is oxygen.
It is about neutrons and protons. The total of neutrons and protons.
Neon has 10 protons and 9 neutrons.
Ah, boron is a lovely element with 5 protons in its nucleus, giving it an atomic number of 5. Just imagine those protons like little seeds of creativity, helping boron bond with other elements and create beautiful compounds in nature. Keep exploring the wonders of the periodic table, my friend, and let your curiosity bloom like a happy little tree.
Sodium, Na, is the element that has eleven protons.
carbon has six protons and six neutrons
Number of protons + Number of neutrons = Mass number(number of nucleons)
