Question

The element hydrogen has three naturally occurring isotopes. Which of
the following describes the relationship of these isotopes? *
different mass, different atomic number
O same mass, different atomic number
O different mass, same atomic number
O same mass, same atomic number

Answer 1

Answer:

option C

Explanation:

isotopy is a phenomenon where an element have the same atomic number but different mass number.the isotopes of hydrogen include,protium, deuterium,and tritium.They all have atomic number of 1 but different mass number of 1,2,3 respectively.

Answer 2

The three naturally occurring isotopes of hydrogen have the same atomic number while they have different masses.

What are Isotopes?

The isotopes can be defined as the member of the same family of an element having the same number of protons but a different number of neutrons.

What are isotopes of Hydrogen?

The hydrogen family has three naturally occuring which are represented by ¹H, ²H, and ³H, and their names are Protium, Deuterium, and Tritium. Out of the three isotopes, isotope ³H is unstable while the other two isotopes are the stable isotopes of hydrogen.

The number of neutrons in the three isotopes are:

¹H = Protium has 0 number of protons,

²H = has only 1 proton,

³H = Tritium has 2 number of protons,

hence, the three naturally occurring isotopes of hydrogen have the same atomic number while they have different masses because of the different numbers of neutrons present.
