## Related Questions   Boron - B - Group IIIThe atomic number is 5.The mass number is 11. Boron is a non metal element. Atomic mass number of it is 11. Boron is a metal element. Atomic mass of it is 11.   If you see the on the periodic table of elements, you can see boron on the right side. The number on the top of the symbol(which is B for Boron) is the atomic number. For any element, subtract the atomic mass from the atomic number. Boron is a non metal element. Atomic mass of it is 10.81. Boron is a non metal element. Atomic mass of it is 10.81. what is the boron number in an atomic number/ take the mass number of boron-10 and subtract the atomic number then divide that number by mass number then multiply it by 100 Boron is a non metal element. Atomic mass of it is 10.811. Boron is a metal element. Atomic mass of it is 11. Five. The Atomic Number of Boron is 5 so it has five protons and 5 electrons. The Mass number of Boron is 11. Mass minus atomic number = number of neutrons = 6. BORON:Electrons = 5 Protons = 5 Neutrons = 6 The number of protons in an element is its atomic number. Boron's atomic number is 5 - ergo, there are 5 protons. The number of neutrons in an element is the difference between the atomic mass and the atomic number of an element. boron's atomic mass is 11. Therefore, 11 - 5 = 6. There are 6 neutrons in boron. In conclusion, there are 6 neutrons and 5 protons in boron. Boron is a non metal element. Atomic mass of it is 11. 5 protons and 5.81 Neutrons. 10.81 is the Atomic Mass Unit and 5 is the Atomic Number of Boron. The atomic number is the number of Protons The mass number is the number of Protons and Neutrons The number of Electrons always equals the number of Protons Therefore according to the above information the atomic number of the atom is 5 HOWEVER there is NO element with a mass number (atomic mass) of 9 with an atomic number of 5. You question is impossible to answer. Beryllium has an Atomic mass of 9.0122 and an Atomic number of 4 Boron has an Atomic mass of 10.811 and an Atomic number of 5 Let's see. The atomic mass is the total number of protons and neutrons. The atomic number is the total number of protons. That means that when we subtract the atomic number from the atomic mass we will get the number of neutrons. We can get the equation: Atomic mass - Atomic number = Neutrons. It can be expressed: 11 - 5 = ?. Whoops, I forgot how to do arithmetic. 6 Every isotope of every element has a different atomic mass. There is no reason for boron to be an exception. Boron is a non meta element. Atomic number of it is 5. Boron Boron BoronBoron's atomic number is 5, meaning 5 protons and 5 electrons.Boron's Relative Atomic Mass is approximately 10.8To find neutrons, you subtract the atomic number from the atomic mass.10.8 - 5 = 5.8 (or 5)Boron has 5 protons, 5 electrons and 5.8 neutrons ###### BoronMathematical ConstantsChemistryAtomic MassAtoms and Atomic StructureNumbers Elements and CompoundsScience Copyright © 2020 Multiply Media, LLC.
