2(IIA) Because The elements in Group 2 (IIA) are metals with a +2 oxidation state. Thus one atom of a Group 2 metal can combine with 2 atoms of chlorine (oxidation state = -1)
An element that can form a chloride with a general formula of MCl2 is considered to have a +2 oxidation state, and an element that can form a chloride with a general formula of MCl3 is considered to have a +3 oxidation state. Some examples include iron, with FeCl2 and FeCl3, and aluminum, with AlCl2 and AlCl3.
There is no chlorine chloride. The formula for a molecule of chlorine is Cl2.
Thallium is an element on the periodic table. It's atomic number is 81.Because it is an element, I don't understand what you mean by "its formula".The symbol for Thallium is Tl, so the formula would be Tl...If you want the formula for a compound with thallium, that's a different story.It is not a diatomic element, if that's what you meant.For more information on thallium, go tohttp://en.wikipedia.org/wiki/Thallium
NaOCl is a compound because it is composed of three elements. If it's not on the periodic table, then it's not an element. Na, O, and Cl are on the periodic table, so they are elements. When they combine, they form compounds.
Sulfur or sulphur is a chemical element, number 16 on the periodic table. The formula for sulfur is S
The element that can form a chloride with the general formula of MCl2 is transition metal elements such as copper (Cu), iron (Fe), or zinc (Zn).
H2O2 is not a Periodic Table element. It is a compound, specifically hydrogen peroxide.
An element that can form a chloride with a general formula of MCl2 is considered to have a +2 oxidation state, and an element that can form a chloride with a general formula of MCl3 is considered to have a +3 oxidation state. Some examples include iron, with FeCl2 and FeCl3, and aluminum, with AlCl2 and AlCl3.
Ethanol is not an element, it's formula is c2h5oh
Yes, each element on the periodic table has a unique name and chemical symbol.
Sodium chloride (NaCl) contain in the formula unit sodium and chlorine.
The sodium ion is Na+; the chloride ion is Cl-. The chemical formula of sodium chloride is NaCl.
ZnCl2 is the chemical formula of zinc chloride.
Sodium is a chemical element with the chemical symbol Na.Salt (table) is sodium chloride with the chemical formula NaCl.
MgCl2 is NOT an element, but a compound (named magnesium chloride), made up of two elements Mg and Cl.
The meaning is that only one atom of this element exist in the molecule. Example: sodium chloride - NaCl.
Sodium chloride is a compound. Its formula is NaCl.
