Answer:
The correct answer is: <em>They each partially describe the bonding in a molecule.</em>
Explanation:
Some chemical molecules cannot be described completely by using only one Lewis structure. In these cases, we can describe the molecule by drawing 2 or more Lewis structures, and the structures are called <u>resonance structures</u>. The overall molecular structure is explained by all the resonance structures together. So, they each describe the bonding in the molecule only partially.

Answer:
C.Tritium
Explanation:
Isotopes are forms of an element with different mass number but same atomic number. Mass number is the sum of the number of protons and neutrons in the nucleus of an atom, while atomic number is the number of protons.
Mass number = protons +neutrons.
Atomic number = protons only
We can say that mass number = atomic number + number of neutrons.
The number of neutrons is what differentiates the isotopes of an element.
For hydrogen element, it has three isotopes namely; protium, deuterium and tritium which have 0,1 and 2 neutrons respectively. Thus the answer is C
