Dear friend,
Because the water remains water throughout this process, it is not undergoing any chemical change. There is no new substance or element added but only a change of form.
It is usually measured on the Pauling scale, on which the most electronegative element (fluorine) is assigned an electronegativity of 4.0. Each of these elements has a low electronegativity on the Pauling scale, and the electronegativities clearly decrease down the group.
Gallium trichloride is the name of GaCI3.
Explanation:
The compound having chemical formula GaCl3 is Gallium trichloride.
The rules for naming a compound according to IUPAC is:
The net charge should always be zero in ionic compounds the prefixes are used as mono, di, tri and so on.
Metal name should come first.
Non-metal name proceed it
The anion ends with suffix 'ide'
Ga³+ + Cl- ⇔ GaCl3
In this gallium Ga is metal and Cl is non-metal with prefix 3.
In solid state the Gallium trichloride exists as a dimer which has formula as
Ga2Cl6.
It has the property of being soluble in all the solvents including alkanes.
