Question

Sir
I am Shaun job of class 9. I have a doubt regarding chemistry on the topic of the structure of an atom
This is the question .
Why does an atom show isotopes ? Do all elements show isotopes?Can you name some uses of these ?
Thank you for your time Sir

Answer 1

Isotopes are variants of a particular chemical element which differ in neutron number. All isotopes of a given element have the same number of protons in each atom.

Most isotopes occur naturally due to different number of neutrans in atoms of same element.

Not all elements have isotopes, onle certain elements have been known to have isotopes.

Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes.
