Question

arrange the following as per instructions given in the brackets​

Answer 1

$\underline \bold{ATOMIC \: SIZE }$

The distance between the centre of nucleus to the outermost shell of is called atomic size.

◼It increases across a group due to increase in shells but decreases across a period .

$\underline\bold{IONISATION \: POTENTIAL }$

The amount of energy required to remove a loosely bound electron from the outermost shell of an isolated gaseous atom .

◼It increases across a period but decreases across a group.

$\underline\bold{ELECTRON \: AFFINITY}$

The amount of energy released when an atom in gaseous state accepts an electron to form an anion.

◼t increases across a period but decreases across a group.

$\underline \bold{ELECTRONEGATIVITY}$

The tendency of an atom to attract electrons towards itself when combined in a compound.

◼It increases across a period and decreases a group.

$\underline\bold{METALLIC \: PROPERTY }$

◼It increases down a group and decreases across a period.

$\bigstar \large \bold{1)Mg ,Cl, Na, S, Si (decreasing \: order \: of \: atomic \: size) }$

By convey from above information it will be,

$\large \boxed{2)Na,Mg,Si,S,Cl}$

$\bigstar \large \bold{2)Cs ,Na, Li, K, Rb(increasing \: order \: of \: metallic \: properties ) }$

By convey from above information it will be,

$\large \boxed{Li,Na, K, Rb,Cs}$

$\bigstar \large \bold{3)Na,K,Cl,S,Si(increasing \: order \: of \: ionisational \: potential ) }$

By convey from above information it will be,

$\large \boxed{K,Na,Si,S,Cl}$

$\bigstar \large \bold{4)Cl , F, Br, I(increasing \: order \: of \: electron \: affinity )}$

By convey from above information it will be,

$\large \boxed{I,Br,Cl,F}$

$\bigstar \large \bold{5)Cs,Na,Li,K,Rb(decreasing \: order \: of \: electronegativity )}$

By convey from above information it will be,

$\large \boxed{Li,Na,K,Rb,Cs}$
