Write the isotope symbol for two isotopes of the same element. What makes the isotopes different? How are they similar?

x y

A and A, where x and y are the mass b b numbers, b is the atomic

and A is the chemical symbol of the element

They are different because they have different mass numbers and are similar because they have the same atomic number

Explanation:

Isotopes are atoms that have the same atomic number but different mass numbers due to the difference in neutron number.
