316204 Which is true for an element present in III group of the periodic table?

1 It has oxidation state of +4

2 It is gas at room temperature

3 It forms

R_{2} O_{3}

4 It forms

R X_{2}

Explanation:

III A group element have ' 3 ' valence $e^{-}$ . So, they form $R_{2} O_{3}$ type oxides.

CHXI11:THE P-BLOCK ELEMENTS

316205 Which metal has a greater tendency to form metal oxide?

1

Al

2

Ca

3

Cr

4

Fe

Explanation:

The reactivity order of metals is given below:
$K > Na > Ca > Mg > Zn > Fe > Pb > Cu > Ag$
Based on the reactivity series of metallic elements $Ca$ has the more tendency toform oxides than the other.
