GrogVix [38]

Answer:

The correct answer is C. element

Explanation:

The sample cannot be an element because an element - or <em>elemental substance</em> - cannot be decomposed into simpler substances. Thus, it cannot be composed by differents types of atoms. For example, an element is carbon (C).

As the sample contains <u>three types of atoms</u>, it can be a compound, a molecule or a mixture, because they can be composed by different types of atoms - of different chemical elements. For example, the sample could contain the element carbon (C) combined with other elements, for example oxygen (O) or hydrogen (H), amoing others.

  2. When these elements are <u>chemically</u> combined, a new substance is formed with new chemical and physical <u>properties</u>.
  3. An element is a <u>pure</u> substance that cannot be separated into simpler substances by <u>physical</u> or chemical means.
  4. A compound is two or more elements <u>combined</u> chemically to produce a new substance.
  5. When two or more elements chemically combine, the compound has new properties, different from the chemical and physical properties of the <u>original</u> elements.

<h3>What is a chemical element?</h3>

A chemical element can be defined as a pure substance which comprises atoms that have the same atomic number (number of protons) in its nuclei and as such it is the primary constituent of matter.

Generally, some examples of a chemical element include the following:

  1. Argon.
  2. Sodium.
  3. Carbon.
  4. Oxygen.
  5. Hydrogen.
  6. Phosphorus
  7. Copper
  8. Aluminum
  9. Potassium
  10. Magnesium

<h3>What is a pure substance?</h3>

A pure substance can be defined as a single sample of matter that cannot be separated into other kinds of matter through the use of any physical or chemical separating technique because it has distinct chemical properties and a definite and constant composition.
