An atom of an element contains 13 electrons. Its nucleus has 14 neutrons. Fid out its atomic number and approxiamte atomic mass. An isotope has atomic mass 2 units higher. What will be the number of protons, neutrons and electrons in the isotope?

Text Solution

Verified by Experts

The correct Answer is:
At. No=13, atomic mass =27; the isotope will hae same number of protons and electrons=13 but neutrons will be 14+2=16.
