The atomic number of an element 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-5Z)=11-5=6
Since the atomic number is 5, the element is boron and is represented as : `._(5)^(11)B`
