Interpretation:
Boiling point of argon has to be estimated.
Concept Introduction:
Elements with same valence electrons are placed in the same group in periodic table
Chemical properties of an element can be determined by the number of electrons in the subshell containing the outermost electrons.
The elements with same number of valence electrons have physical and chemical properties.
Noble gases are inert gases with completely filled electronic configuration. Helium, neon, argon, xenon, krypton, and radon are the noble gases.
Group 8A in the periodic table contains 8 valence electrons and the outer electronic configuration of noble gases is
Boiling point: It is the temperature at which liquid converts to vapor. At boiling point the vapor pressure of liquid and the pressure of the surroundings are equal.
