Electronegativity
Electronegativity is the characteristics of any atom that determines how strongly it will attract the electron cloud to itself. Its simply to say that a tendency of getting negative charge by attract the electron to itself.
In a bond of two atom the more electronegative atom will attract the electron with stronger than other. Hence, it will be partially negatively charged.
In HCl chlorine is more electronegative than hydrogen. Hence it attracts electron to itself. The electron cloud nearby chlorine is more dese than the electron cloud of nearby hydrogen. Hence, chlorine is partially negative charged and hydrogen is partially ppsotive charged. The phenomenon in HCl may defined as polarity.
