How many atoms are in potassium?
Understand the Problem
The question is asking for the number of atoms present in a given amount of potassium. To determine this, we typically refer to the molar quantity, where one mole of any element contains Avogadro's number of atoms, approximately 6.022 × 10²³. The question does not specify a particular quantity of potassium, so the answer could vary based on context.
Answer
1 atom in a single atom of potassium or atomic number 19.
If referring to a single atom of potassium, there is 1 atom. If referring to the atomic number of potassium, it is 19. The number of atoms in a sample would depend on the sample's mass or moles.
Answer for screen readers
If referring to a single atom of potassium, there is 1 atom. If referring to the atomic number of potassium, it is 19. The number of atoms in a sample would depend on the sample's mass or moles.
More Information
Potassium is a chemical element with the symbol K and atomic number 19, meaning each potassium atom has 19 protons. In the context of a sample, the number of atoms varies based on the mass or number of moles.
Tips
Understand the context of the question: differentiate between atomic number, single atom count, and number of atoms in a sample.
