Question

1 Paragraph- Most of the known elements udVe fractional atomic masses. For example, the atomic mass of chlorine is 355. Such elements exist in different forms known as isotopes. These are regarded as the atoms of the same element having same atomic number but different mass numbers. 1. Why do isotopes of an element differ in their mass numbers? 2. Do the isotopes of an element show same chemical characteristics? 3. Do isobars belong to the same element? 4. If not, what is the reason behind it ? ​

Answer 1

Explanation:

the atomic mass of chlorine is 355. Such elements exist in different forms known as isotopes. These are regarded as the atoms of the same element having same atomic number but different mass numbers.
