Question

1)Zinc is non-ductile and non-malleable.

2) Sodium & Potassium r soft solids.

3) Lead has low melting point.

STILL Y THESE R CONSIDERED AS "METALS"?

Answer 1

yes this is because metals are those elements having valence electrons of less than 4 some are of an exception like metalloids as they show properties of both metals and non metals

Answer 2

Explanation:

1) Zinc is non - ductile and non - malleable however zinc is highly reactive metal as is produces basic oxide , forms ionic bond , has high melting and boiling point , is lustrous,zinc lose electrons to gain stability (electro-positive )

2)Sodium and pottasium are present in group 1 in the periodic table and is thus called alkali metal . it is highly reactive and forms basic oxide and is electropositive

3) Lead is a bluish-white lustrous metal. It is very soft, highly malleable, ductile, however it is relatively poor conductor of electricity. and has low melting point that is why it us considered as metal
