Which elemt has 35 protons 45 neutrons 36 electrons and a mass of 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.
How many neutrons does an atom have if it has an atomic mass of 20 and an atomic number of 45?
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.
What is Br number of protons?
Br-80 has 35 protons.
What is the name number tells you the amount of protons and neutrons in an element?
Number of protons + Number of neutrons = Mass number(number of nucleons)
What element has the same number of neutrons and protons?
Atoms having the same number of protons and neutrons make up the same element.

What is Br number of protons?
Br-80 has 35 protons.
Determine the numbers of electrons protons neutrons 80 35 Br?
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.
What element has 8 neutrons 8 protons?
The element that has 8 protons and 8 neutrons is oxygen.
An element's atomic mass number is?
It is about neutrons and protons. The total of neutrons and protons.
How many protons and neutrons are in the element?
Neon has 10 protons and 9 neutrons.
How many protons are in a boron?
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.
What element has 11 protons and 13 neutrons?
Sodium, Na, is the element that has eleven protons.
What element has six protons and six neutrons?
carbon has six protons and six neutrons
What is the name number tells you the amount of protons and neutrons in an element?
Number of protons + Number of neutrons = Mass number(number of nucleons)
