<span>The first part of the cell theory states that all living things on Earth are comprised of cells; this portion of the cell theory was determined by botanist Matthias Schleidan. The second part, determined by zoologist Theodor Schwann, states that cells make up the basic units of every living thing. Physician Rudolph Virchow was responsible for the third part, which states that living cells stem from other living cells.</span>
Answer:
The chemical element which would be the most reactive with other elements is: D. helium, #2.
A chemical property is a property of a chemical substance that is observable and measurable in the course of a chemical reaction. The chemical properties of a chemical substance include the following:
- Tarnishing.
- Heat of combustion.
- Flammability.
- Acidity.
- Chemical reactivity.
Chemical reactivity is a property that determines how readily a chemical element would bond with other chemical elements to form a new compound.
Basically, the ability of a chemical element to bond with other chemical elements is highly dependent on the number of valence electrons.
The chemical elements Neon and Argon are noble elements, and as such have a filled outermost shell and wouldn't react with other chemical elements.
Helium has a single valence electron in its outermost shell while Boron has three (3) valence electrons in its outermost shell.
In conclusion, Helium with an atomic number of two (2) would be the most reactive with other elements.
