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 element has the same number of neutrons and protons?
Atoms having the same number of protons and neutrons make up the same element.
How many protons and neutrons does a nucleus of an atom contain?
Each element has a different number of protons and neutrons. So it changes for each element.
Which elemt has 35 protons 45 neutrons 36 electrons and a mass of 80?
Br^-
How many protons are in a boron?
The element boron has atomic number 5; therefore, there are 5 protons in each boron atom, because the atomic number of an element is defined as the number of protons in each atom of an element.

How many protons neutrons electrons does bromine 80 have?
Br-80 has 35 protons, the element has 35 electrons (bromide anion has one more), and 80-35=45 neutrons.
What is Br number of protons?
Br-80 has 35 protons.
What element has 8 neutrons 8 protons?
The element that has 8 protons and 8 neutrons is oxygen.
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
How many protons and neutrons are in the element?
Neon has 10 protons and 9 neutrons.
An element's atomic mass number is?
It is about neutrons and protons. The total of neutrons and protons.
What element has six protons and six neutrons?
carbon has six protons and six neutrons
Determine the numbers of electrons protons neutrons 80 35 Br?
Number of Protons: 35 Number of Neutrons:45 Number of Electrons:35
What element has the same number of neutrons and protons?
Atoms having the same number of protons and neutrons make up the same element.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
