Question

Atoms of the same element with different number of neutrons are called a. Isotopes b. Copy Cats c. Ions d. Isomers

Answer 1

a. Isotopes

Step-by-step explanation:

If we have same atom but with different number of neutrons then in that case the number of neutrons will decide the mass number of the atom

Mass number = Number of protons + Number of Neutrons

so here we can say that the mass number of the two same atoms would be different while the atomic number would be same

for an example we have

`_1^1H, _1^2H , _1^3H`

so in this example all are hydrogen atom but all have different number of neutrons

all such group of atoms is known as isotopes
