ClO4 is not a compound, it exists as ClO4-, which is a polyatomic ion called the perchlorate ion. Some positive ion such as potassium or ammonium must be present to balance the charge and form a compound.
Any chemical substance that contains only one kind of atoms is an element, therefore Cl2 (chlorine) is an element.
It is not a compound, it is the element chlorine.
Cl2 is molecular chlorine. Chlorine is diatomic, meaning it will naturally pair up.
The name of the compound is chlorine dioxide.
carbonic acid
Cl, chlorine is an element, Cl2 is the molecular form of the element. When 'free' chlorine is so reactive that it will react with itself to form diatomic (2 atoms) molecules, but it is still an element.
There is no number for Cl2.Element Cl has 17 atomic number.
Lime is a compound.
Cl stands for chlorine or chloride as an periodic element
Is gasoline a element a mixture or a compound
It could be either. For example, a molecule of O2 or Cl2 is an element, but one of CH4 or NO3 is a compound.
Cl, chlorine is an element, Cl2 is the molecular form of the element. When 'free' chlorine is so reactive that it will react with itself to form diatomic (2 atoms) molecules, but it is still an element.
If the chemical formula contains only one element (such as Mg, K or Cl2) it would be an element. If it contains two or more elements (such as NaCl, CO2 or CuSO4.5H2O) then it would be a compound.
Chlorine (chemical symbol Cl) is an element. The molecular formula for chlorine as a gas is Cl2. It is not a compound because it's just one element; compounds have two or more elements chemically combined.
Chlorine is not a metalloid. It is a non metal.
When one element replaces another element in a compound during a chemical reaction
Cl2 stands for Chlorine.I2 stands for Iodine.
Chlorine (Cl2) is not an ionic compound. It is a covalently bonded element. Chlorine can form ionic compounds like NaCl (Sodium Chloride) or CaCl2 (Calcium Chloride) but is not itself an ionic compound.
lithium
There is no number for Cl2.Element Cl has 17 atomic number.
A molecule is an element if it contains only one kind of atom, like oxygen, O2, and chlorine, Cl2. A molecule is a compound if it contains more than one kind of atom, such as water H2O, or methane, CH4.
Chlorine gas (Cl2) is covalent.
