Final answer:
In the compound KOH, there is one atom of potassium present.
Step-by-step explanation:
Potassium, denoted by the symbol K, is an element that belongs to the alkali metal group in the periodic table. In the compound KOH, there is one atom of potassium present. The chemical formula KOH represents one molecule of potassium hydroxide, which consists of one atom of potassium, one atom of oxygen, and one atom of hydrogen.
The formula for potassium hydroxide is KOH. This chemical formula indicates that each molecule of potassium hydroxide contains one atom of potassium (K), one atom of oxygen (O), and one atom of hydrogen (H). Therefore, the correct answer to the question 'How many atoms of potassium are there in KOH?' is a. 1.
The Latin name for the element potassium is Kalium, which is why the symbol for potassium is K.
