What is the mass number of Br-79?
Bromine is a non metal element. Atomic mass of it is 80.
How many protons neutrons electrons does bromine 80 have?
Bromine-80 has 35 protons, as all bromine atoms do. The number of neutrons can be calculated by subtracting the atomic number (35) from the atomic mass (80), giving 45 neutrons. In a neutral bromine-80 atom, there are also 35 electrons.
How many neutrons are in 28Al?
number of neutrons = mass number - number of protons = 28 - 13 = 15 neutrons
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)
How many neutrons are in the element bohrium?
For each isotope of bohrium the number of neutrons is different. Number of neutrons = Mass number of an isotope of Bh – 107
What are the protons and the neutrons for the element Br?
Bromine-79 has 44 neutrons and bromine-81 has 46 neutrons. All the isotopes of bromine has 35 protons.
What is Br number of protons?
Br-80 has 35 protons.
What is the mass number of Br-79?
Bromine is a non metal element. Atomic mass of it is 80.
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.
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.
How many protons neutrons electrons does bromine 80 have?
Bromine-80 has 35 protons, as all bromine atoms do. The number of neutrons can be calculated by subtracting the atomic number (35) from the atomic mass (80), giving 45 neutrons. In a neutral bromine-80 atom, there are also 35 electrons.
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.
How many electrons and protons does Br have?
Br has an atomic number of 35 giving it 35 protons. Since it has a charge of 1- it will have 36 electrons to form a octet.Br- will have 35 protons and 36 electrons. The negative charge indicates it gained an electron.
