Question

A metal M has electronic configuration 2, 8, 3 and occurs in earth's crust and its oxide M203. It is more reactive than zinc. Which of the following options (s) is/are correct?
A. The metal M is iron
B. The metal M is lead
C. The ore from which metal M is extracted in haematite.
D. The ore from which metal M is extracted is bauxite.

Answer 1

$\huge\star{\green{\underline{\mathfrak{Answer :-}}}}$

D) The ore from which metal M is extracted is Bauxite.

Aluminium is Metal M.

The metal which has the atomic number 13 is aluminium.

The electronic configuration of aluminium is (2,8,3), as given in the question.

The metal M's oxide given in the question is M2O3. Similarly, we know that aluminium forms oxide as Al2O3.

Aluminium is also less reactive than zinc, as given in the question.

So, we can say that aluminium is the right answer.

$\rule{200}2$

Now, aluminium is obtained from bauxite ore.

Hence, Aluminium is the metal M and option D is correct.
