## How many atoms are present in potassium?

Hint: The molecular weight of potassium is 39 g/mole . This means the weight of 1 mole potassium which contains [6.023{text{ }} times {text{ }}{10^{23}}] number of atoms is 39 g. To calculate the number of potassium in 117 grams of potassium, you should know the mole concept.

## How do you count atoms?

Potassium is the fourth element in the first column of the periodic table. It is classified as an alkali metal. Potassium atoms have 19 electrons and 19 protons with one valence electron in the outer shell. Potassium is considered chemically similar to sodium, the alkali metal above it on the periodic table.

## What atoms does potassium contain?

6.022 x 10^23 x . 0141 about 8.49 x 10^21 atoms

## How many atoms are in potassium?

There are 6.022 xd7 1023 atoms of potassium in every mole of potassium. Since one mole of KOH contains one mole of K, the answer is 6.022xd71023 atoms of K.
