Element M can be a choice of 4 elements, Beryllium, Magnesium, Calcium, or Strontium.
The element must have an oxidation of +2, which means group 2 elements.
The atomic radius of a barium atom is 222pm. Radium has a larger atomic radius that Barium, so that is eliminated, and Barium is the same as Barium so that is also eliminated.
Chlorine is a highly reactive element
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 highly reactive.
Sodium is more reactive then Magnesium as it is a group 1 element and magnesium is a group 2 element
No such substance as 'sodium chlorine'. I think you mean 'sodium chloride'. I which case it is an ionic compound. Separately , sodium(metal) is an element and chlorine(gas) is an element. They both appear in the Periodic Table. 'Mixture', does not come into question.
Magnesium
Sr
MgCl2 contains the elements magnesium and chlorine.
Mg+AlCl=MgCl+Al Magnesium+Aluminium chloride=Magnesium chloride+ Aluminium This happens because magnesium is a more reactive element then aluminum so chlorine swaps places and forms a new compound with magnesium.
Chlorine is a highly reactive element
Yes, chlorine is very reactive.
Magnesium is a chemical element, not a compound.
Argon is a Non-Reactive Element. Magnesium is a very Reactive Element. Magnesium will react violently when ignited in an Oxygen rich environment.
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 highly reactive.
Chlorine is a Highly reactive element.
chlorine is not a compound. it is an element.
