Modern Periodic table all physical and elemental properties
Periodic table all physical and elemental properties
# Atomic size #
Across the period atomic size decreases
Down the group atomic size
Increses
#zeff#
Across the period Zeff charge goes on increasing
(because nucleus and electron attraction was increases )
Down the gropu Zeff charge goes on decreases
(because nucleus and electron attraction was low )
# Ionizationenthlpy (I. P.) #
/ionization potential
Define:- the energy required to remove an electron from the isolated gaseous atom in its ground state is called ionization enthlpy
Across the period ( I.P.) is increases
(atomic size decreases I. p increases)
Down the group (I.P.) is decreases
(atomic size increases I. P. Decreases)
#Electron gain enthelpy(egH) #
Define :- the enthalpy change that takes place when an electron is added to an isolated gaseous atom in its ground state is called the electron gain enthalpy
* More the (-ve )is electron gain enthalpy
More is the stability of that species *
Across the period electron gain enthlpy is highly -ve
(atomic size small electron gain enthlpy is highly (-ve) )
Down the group electron gain enthlpy is low( -ve)
(atomic size big electron gain enthlpy is low( -ve) )
Smaller the size highly -ve will be it's egH (more stable)
Bigger the size low -ve will be it's
egH (unstable)
Periodic trends in metallic -nonmetallic
Character
Metalic character decreases across the period
Metallic character increases down a group
Nobel gases /inert gases are highly positive electron gain enthlpy (because theyare stability order is completed )
Nonmetallic character increases across the period and decreases down the group
