The mass of an atom is found by adding the number of the protons and neutrons. So, a boron atom with 5 protons and 6 neutrons would have an Atomic Mass of 11.

∙ 14y agoLet'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.

How many neutrons are found in the nucleus of a boron -11 (B) atom?
5
How many neutrons dose hassium have?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of hassium is 108; each isotope of an element has a different number of neutrons and a different atomic mass.
How many neutrons are does yttrium have with an atomic number of 39 and atomic mass of 89?
50 neutrons
How many neutrons are in roentgenium?
Roentgenium-272 has 161 neutrons. Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of roentgenium is 111, but Rg has many isotopes each with a different atomic mass and number of electrons.
How many protons and neutrons in meitnerium?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of meitnerium is 109. Each isotope of an element has a different number of neutrons. Meitnerium has 109 protons.
How many neutrons does Boron 11 have?
It has an atomic number of 5 and hence it has 6 neutrons.
How many protons and neutrons are present in boron?
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.
How many electrons does boron have?
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
How many neutrons are found in the nucleus of a boron -11 (B) atom?
5
How many electrons protons neutrons boron have?
5 Protons,6 Electrons,5 Neutrons
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 protrons and neutrons does boron contain?
5 Protons, 6 Neutrons. For future reference, the protons is the atomic number (right above the element symbol) To get the neutrons you subtract the atomic mass (underneath the symbol) by the number of protons. You have to round this number.
How many neutrons are there in boron?
it has 5 protons and 5 neutrons.
How many protons neutrons and electrons are in Bi?
Five proton and electrons, 6 neutrons. This because this is the atomic number of boron, which states how many protons and electron in the element. For neutrons you must subtract the atomic number (5 in this case) from the rounded. average atomic mass.
How many protons electrons and nuetrons does boron - 10 have?
Boron's atomic number is 5. So there are 5 protons and 5 electrons. In Boron-10, there are 5 neutrons (10 - 5 = 5)
How many atomic number of boron?
There is only one atomic number for any element. For boron, it is 5.
How many electrons is there in boron if there is a atomic number or 5 and atomic mass of 11?
All you need is the atomic number, which gives the number of protons, in this case, 5. In any neutral atom the number of electrons is the same as the number of protons. So any neutral boron atom will have 5 electrons.
