The atomic number of an clement is 5 and mass number is 11. Find the number of electrons, protons and neutrons present in an atom of it. How can this element be represented.

Text Solution

Verified by Experts

Number of electrons (Z = 5) = 5
Number of protons (Z = 5 ) = 5
Number of neutrons (A-z) = 1 - 5 = 6
Since the .atomic number is 5, the element is boron and is represented as: `""_(5)^(11)B`
