Answer:
What is the question? It looks like a fact.
Explanation:
Isotopes are chemical elements with same atomic number (Z), but different mass number (different number of neutrons).
Hydrogen is an element with atomic number 1. It has three isotopes:
1) protium (₁¹H), with mass number 1 (no neutrons).
2) deuterium (₁²H), with mass number 2 (one neutrons, n° = 2 -1, n° = 1).
3) tritium (₁³H), with mass number 3 (two neutrons, n° = 3 -1, n° = 2).
Answer is: D- there are different elements as products.
In balanced chemical reaction, there are same elements and number of elements on both sides of the reaction.
In nuclear reaction there are different elements and number of elements on the nuclear reaction.
For example nuclear reactions are alpha and beta decay, where new elements have different atomic and mass number.
