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.
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.
No. It's a molecular element.
PB is an element. It is the chemical symbol for lead.
Ag is the chemical symbol for silver, which is an element. It is not a compound.
Hl is an element. It is the chemical symbol for the element helium on the periodic table.
Cl2 stands for Chlorine.I2 stands for Iodine.
Chlorine is a nonmetal but its is an element, not 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.
Chlorine is not a metalloid. It is a non metal.
A molecule can be either an element or a compound, depending on its composition. If a molecule consists of only one type of atom, it is an element. If a molecule is made up of two or more different types of atoms bonded together, it is a compound.
When one element replaces another element in a compound during a chemical reaction
No. It's a molecular element.
lithium
Chlorine gas (Cl2) is covalent.
"I believe it is Ionic." Whoever said this is wrong, it's covalent (they share an electron from each atom to stabillise themselves) with an instantaneous dipole induced dipole intermolecular force.
Yes, Cl2 is a molecule composed of two chlorine atoms bonded together. Chlorine (Cl) is a chemical element on the periodic table.
