2. Deduce Each atom of protium has one proton, no neutrons, and one electron. Each
atom of deuterium has one proton, two
neutrons, and one electron. Are these the
same or different elements? Why?

Yes they are.

A element is characterized by the number of protons it has. As the number of protons is the same, then deuterium and protium are the same element, Hydrogen.

Explanation:

What you are seeing is the phenomenon of Isotopy. That happens, isotopy, every time that one atom has the same quantity of protons of another, but a different mass. That difference is caused by the number of neutrons, which variates.

linnaeus is the father of taxonomy

explanation:

which is the system of classifying and naming organisms. one of his contributions was the development of a hierarchical system of classification of nature. today, this system includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species.
