Answer:
A chemical element is a substance that contains only one type of atom, which is the smallest particle of an element. Atoms are made up of protons, neutrons, and electrons.
Explanation:
Substances in the simulation that have particles that are only atoms likely exist in their elemental form, like noble gases such as helium or metals like gold and silver. These substances are not compounds, but standalone atoms.
The substances in the simulation that have particles that are only atoms can be substances in their elemental form. This is especially true in the case of noble gases like helium, neon, and argon which are monoatomic; they consist of independent atoms rather than molecular combinations. Similarly, many metals like gold, silver, and copper also exist as atomic structures rather than molecular compounds. Always remember that substances that consist of only atoms usually exist in elemental form and not as compounds.

The correct answer is false.
It is false the demographics of scientific polls like the Gallup® poll are the same as an online survey.
Since 1935, the Gallup poll has been researching to get data from every type of company or human behavior. Its demographics of scientific polls are more in depth and specific, with different measurement techniques that a simple online survey such as the ones newspapers do. Gannup's polls are more specialized.
