Question

22. Naturally occurring hydrogen consists of three isotopes, hydrogen-1 (1.07 u)
hydrogen-2 (2.02 u) and hydrogen-3 (3.01 u), where the isotopic masses are given
parentheses. Use the periodic table and determine which isotope is present inue
larger percentage in the natural element.
a. Hydrogen-1
b. Hydrogen-2
c. Hydrogen-3
d. each is present at equal percentages.

Answer 1

Answer:

The answer to your question is: a. Hydrogen-1

Explanation:

Hydrogen-1 (1.07 u)

Hydrogen-2 (2.02 u)

Hydrogen-3 (3.01 u)

Periodic table says that H has an atomic mas of 1.008

Then, the reported atomic mass is closer to the mass of the smaller isotope, so Hydrogen-1 must be present in larger percentage.
