Cl2 is a molecule formed of 2 atoms of Chlorine.
There are five atoms in Hg2SCl2: 2 atoms of mercury (Hg), 1 atom of sulfur (S), and 2 atoms of chlorine (Cl).
The ratio of atoms in mercurous chloride (Hg2Cl2) is 2:2:2, as there are two atoms of mercury (Hg) and two atoms of chlorine (Cl) in each molecule of mercurous chloride. This means the ratio of mercury to chlorine atoms in mercurous chloride is 1:1.
There are 5 atoms in Hg2Cl2: 2 mercury atoms (Hg) and 3 chlorine atoms (Cl).
2
If you mean Cl2, that's two atoms (hence the 2).
To make 1 mercuric chloride molecule, you would need to combine 1 mercury atom with 2 chlorine atoms. This reaction forms the compound HgCl2, which is commonly known as mercuric chloride.
There are two chlorine atoms in the molecule NICl2.
2SnCl4 has 10 atoms. There are two molecules of the equation, each with 1 Sn atom and 4 CL atoms.
2 -- Cl2 is a molecule of Chlorine and as can be seen it has two atoms.
Totally three atoms One barium and two chlorine atoms
Well the atoms are Chlorine (Cl) and Hydrogen (H) and the molecule is HCl which is made of one Chlorine atom and one Hydrogen atom (2 atoms altogether) However the "2" in the front of "HCl" means that there are two molecules of HCl and therefore there are FOUR atoms present.
