Question

Isotopes have same atomic masses and have same atomic number and have similiar chemical properties​

Answer 1

Isotopes of an element have similar chemical but different physical properties. Isotopes of an element have same atomic number but different mass number. Hence, they have same number of electrons. Chemical properties are related to the number of valence electrons. Thus, isotopes have similar chemical properties. Physical properties are related to atomic mass. Isotopes of an element have different mass number. Hence, they have different physical properties.
