Question

which of the following is heaviest metal a) Pb, As, Al, Ni

Answer 1

Hi friend,


The heaviest metal among the given sequencial is Pb(Lead).


This is because the mass number of the lead (:-82) is the greatest of all other elements .

Hope this helps you...

Answer 2

Lead (Pb) is the heaviest metal in the given metals.

Explanation:

Atomic weight of lead is 82. Lead is denser than most of the common materials. Lead is malleable and soft and its melting point is relatively low. In comparison with any stable element Lead has the highest value of atomic number.

Then, the endpoints of three of its isotopes are major nuclear decay chains of heavier elements. Relatively Lead is an unreactive post-transition metal.

Lead is having high density and also having low melting point, ductility and relative inertness to oxidation make it useful. These properties are combined with the abundance of itself and low cost, results in the extensive uses in constructions.
