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 an element which means that it's a pure element.
Neither.
Cl2 is the element chlorine.
It is an element.
CH2O is the compound formaldehyde.
There is no number for Cl2.Element Cl has 17 atomic number.
Cl stands for chlorine or chloride as an periodic element
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.
No, one atom of the element Calcium (Ca) reacts with a molecule of Chlorine Gas which has two atoms of chlorine (CL2) to form on molecule of Calcium chloride (CaCl2) :-Ca + CL2 = CaCL
P4+Cl2 P4+Cl2
lithium
There is no number for Cl2.Element Cl has 17 atomic number.
Aluminium.
No - chlorine exists as Cl2 and is thus diatomic.
No, it is a gas consisting of Cl2 molecules (a diatomic element)
No, it is an diatomic element gas, Cl2 called chlorine
No - chlorine exists as Cl2 and is thus diatomic.
Cl stands for chlorine or chloride as an periodic element
yes its a reactive element c12 and al do react
its a non polar bond non polar bonds exist between two of the same element like Cl2 in this case
oxygen gas is an element, it just travels around as O2. like chlorine (Cl2).
It could be either. For example, a molecule of O2 or Cl2 is an element, but one of CH4 or NO3 is a compound.
