two elements and two atoms (potassium and chlorine)In one molecule of KCl, there are two elements (potassium and chlorine).The molecular weight of KCl is 74.55 g / mol.So, 74.55 g of KCl will contain 6.023 x 1023 molecules or 12.046 x 1023 atoms.
There are two types of atoms in KCl, potassium (K) and chlorine (Cl). The chemical formula KCl indicates that there is one atom of potassium and one atom of chlorine in each molecule of KCl.
In KCl, there are two elements: potassium (K) and chlorine (Cl).

The formula for potassium chloride is KCl. The elements found in KCl are potassium and chlorine.
To find the number of K atoms in KCl, we first calculate the molar mass of KCl: 39.10 (K) + 35.45 (Cl) = 74.55 g/mol. Next, we determine the number of moles of KCl in 2.77g: 2.77g / 74.55 g/mol = 0.0371 mol. Since there is 1 K atom in 1 KCl molecule, the number of K atoms in 2.77g of KCl is the same as the number of moles of KCl, which is 0.0371 mol.
The formula unit of potassium chloride (KCl) has two atoms.
It should be written as KCl, it is called Potassium chloride and it is composed of Potassium (K) and Chlorine (Cl).
K+ And CL- or Potassium and chlorine.
The oxidation numbers for the atoms in the ionic compound KCl are K+1 and Cl-1.
For example: NaCl, KCl, HCl.
