What is the subscript for Cl2?
Re: Cl vs Cl2 Yes, chlorine gas is Cl2. There are 7 diatomic molecules (H,O,N,Cl,Br,I,F), so whenever these are gases or “exist naturally”, you should use the subscript 2.
What does the 2 subscript mean in f2?
The symbol for the element oxygen, O, represents both the element and one atom of oxygen. A molecule of oxygen, O2, contains two oxygen atoms; the subscript 2 in the formula must be used to distinguish the diatomic molecule from two single oxygen atoms.
What do the two subscripts in the formula indicate?
The numbers appearing as subscripts in the chemical formula indicate the number of atoms of the element immediately before the subscript. If no subscript appears, one atom of that element is present.
What does the subscript in a chemical formula indicate?
A molecular formula is a representation of a molecule that uses chemical symbols to indicate the types of atoms followed by subscripts to show the number of atoms of each type in the molecule. (A subscript is used only when more than one atom of a given type is present.)
What does Cl2 stand for?
Chlorine | Cl2 – PubChem.
Is chlorine Cl or Cl2?
Chlorine is called Cl2 because it is a diatomic molecule. Diatomic means there are two atoms of the same elements in the molecule. Cl is elemental form of chlorine which exists in periodic table.
How does Cl become Cl2?
At standard temperature and pressure, two chlorine atoms form the diatomic molecule Cl2. Along with fluorine, bromine, iodine and astatine, chlorine is a member of the halogen series that forms the group 17 of the periodic table – the most reactive group of elements. It combines readily with nearly all elements.
What is Cl2 wire?
CL2: This is a cable jacket fire resistance rating defined in Article 725 of the National Electric Code. It stands for “Class 2 Remote-Control, Signaling, and Power-Limited Circuits” cable, which indicates that the cable is suitable for in-wall installation and use for certain low-voltage applications.
Why chlorine is written as Cl2?
Answer: Explanation: We write chlorine as CL2 because chlorine is a non metallic gas . Also as chlorine is a gas it occurs in diatomic form as cl2 such as hydrogen(h2).
