2) Which of the following statements best describes an element?

A) a material that has consistent physical properties

B) a material with more than one type of atom

C) a material that is pure

D) a material that has consistent chemical properties

E) a material consisting of only one type of atom

E

Explanation:

The answer woul be E because elements are made of one type of atoms

The correct answer is E) a material consisting of only one type of atom.

Explanation:

A chemical element is called a substance that is formed by atoms of the same type whose nuclei have the same number of protons, called atomic number.

It is considered a chemical element to the simplest form of a substance, therefore it is that substance that cannot be decomposed by a chemical reaction into simpler ones.

The elements combine to form compounds. The chemical behavior of the elements is related to the structure of the nucleus and the configuration of its electrons.

The chemical elements and their characteristics are summarized in what is called a periodic table of the elements, where the elements are arranged in increasing order of atomic number.

Finally, the correct answer is E) a material consisting of only one type of atom.
