Define:
Metallic character

Assertion :- Metallic character increases on going down the group Reason :- I.E. decreases on going down the group

Which of the following properties of IA group metals increases as the atomic number rises: (a) Metallic character (b) Ionic radius (c ) Melting point (d) Density (e ) Ionization potential Correct answer is:-

Assertion: Metallic character increases from left to right among the elements of 2nd period. Reason: Second period is called shortest period.

Assertion (A) : Metallic character order is K gt Mg gt Al gt B . Reason (R ) : Along the period (rarr) metallic character increases and decreases down the group (darr) .

Metals have few electrons in their valence shell while non-metals generally have more electrons in their valence shell. Metallic character is closely related to atomic radius and ionisation enthalpy. Metallic character increases from top to bottom in a group and decreases from let to right in a period of periodic table. metallic character is inversely related to electronegativity of element. Q. The electronegativity of the following elements increase in the order:

Assertion:Metallic character is highest at the extremely left side of the periodic table. Reason:Ionization enthalpy increases across a period.

Metals have few electrons in their valence shell while non-metals generally have more electrons in their valence shell. Metallic character is closely related to atomic radius and ionisation enthalpy. Metallic character increases from top to bottom in a group and decreases from let to right in a period of periodic table. metallic character is inversely related to electronegativity of element. Q. 3 N_0//2 atoms of X_((g)) are converted it into X_((g))^(+) by energy E_(1) , 2 N_0//3 atoms of X_((g)) are converted it into X_((g))^(-) by energy E_(2) . hence, ionisation potential and electron affinity of X_((g)) are: ( N_(0) =Avogadro's number)

The correct of the metallic character is :

The correct order of the non - metallic character is :

Arrange the elements of period 3 in decreasing metallic character.
