CHXI03:CLASSIFICATION OF ELEMENTS AND PERIODICITY IN PROPERTIES

313133 Both lithium and magnesium display several similar properties due to the diagonal relationship; however, the one which is incorrect is :

1 Both form basic carbonates

2 Both form soluble bicarbonates

3 Both form nitrides

4 Nitrates of both Li and Mg yield

N O_{2} a n d O_{2}

on heating

Explanation:

Mg can form basic carbonate like
$3 M g C O_{3} . M g {(O H)}_{2} .3 H_{2} O ↓$
While Li can form only carbonate $(L i_{2} C O_{3})$ not basic carbonate.

313134 Lithium shows diagonal relationship with

1

Mg

2

Al

3

Be

4

Na

Explanation:

$Li - Mg, Be - Al$ and $B - Si$ show diagonal relationship. It is due to similar radii, similar electronegativity and similar polarising power.

313135 $Mg$ and $Li$ are similar in their properties due to

1 same e/m ratio

2 same electron affinity

3 same group

4 same ionisation potential

Explanation:

$Mg$ and $Li$ are similar in their properties due to the similar electronegativity and polarising power, i.e. they have same charge/radius (e/m) ratio.
