In: Physics
you are given one atom of the element 11-B5-. How many protons are in this element?
How many neutrons are in the element
How many electrons are in the element
The given element is Boron with symbol B.The atom is represented as 11B5 in the question.
Where 11 = A ,the atomic mass and 5 = Z ,the atomic number.
The number of protons in an element= Z ,atomic number.
So the number of protons in the element = 5
The number of neutron= A-Z = 11-5 = 6
So the number of neutrons in the atom is 6.
As atom of the element given is neutral in charge, it will have the number of electrons and protons as same.
So the element has 5 electrons.
