Is there a CL element?
Chlorine (Cl), chemical element, the second lightest member of the halogen elements, or Group 17 (Group VIIa) of the periodic table.
What is CL symbol in chemistry?
Cl-
Chloride/Formula
Is cl2 a chlorine?
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 does the element CL represent?
Chlorine is a chemical element with symbol Cl and atomic number 17. Classified as a halogen, Chlorine is a gas at room temperature.
Is Cl an acid or base?
A strong acid like HCl donates its proton so readily that there is essentially no tendency for the conjugate base Cl– to reaccept a proton. Consequently, Cl– is a very weak base.
Is chlorine Cl or CI?
Chlorine is a chemical element with symbol Cl and atomic number 17. Classified as a halogen, Chlorine is a gas at room temperature…….Is the symbol for chlorine Cl or CI?
| Atomic Mass | 35.45u |

What is the symbol of fluorine?
F
Fluorine/Symbol
Is chlorine CI or Cl?
Why is Cl always 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).
Is CL metal or nonmetal?
Oxygen, carbon, sulfur and chlorine are examples of non-metal elements. Non-metals have properties in common.
Is no3 acidic or basic?
Table of Acid and Base Strength

Why is Cl A neutral anion?
water and forms a weak acid, while the Cl-, the anion of strong acid HCL, forms a spectator ion. Salts that are from strong acids and strong bases normally do not hydrolyze and no reaction occurs between the ions and water; therefore, the solution remains neutral with a pH=7.
Is CL an element?
Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them.
What are all the elements and their symbols?
Hydrogen (H)
What is the symbol for elements?
Atomic symbol: The atomic symbol (or element symbol) is an abbreviation chosen to represent an element (“C” for carbon, “H” for hydrogen and “O” for oxygen, etc.). These symbols are used internationally and are sometimes unexpected.
What are the elements of an element?
An element is a pure substance that is made from a single type of atom . Elements are the building blocks for all the rest of the matter in the world. Examples of elements include iron, oxygen, hydrogen, gold, and helium. An important number in an element is the atomic number. This is the number of protons in each atom.
