Question

The position in the periodic table to which the $Al$ metal belongs:
(A) Alkali metals
(B) Alkaline earth metals
(C) d-block elements
(D) p-block elements

Answer 1

The periodic table, otherwise called the periodic table of components, is an even presentation of the chemical components, which are orchestrated by nuclear number, electron setup, and repeating chemical properties. A block of the periodic table is a bunch of components brought together by the orbitals their valence electrons or vacancies lie in. The term seems to have been first utilized by Charles Janet. Each block is named after its trademark or characteristic orbital: s-block, p-block, d-square, and f-block.

Complete answer:
Specific regions of the periodic table can be alluded to as blocks in recognition of the arrangement in which the electron shells of the components are filled. Components are assigned to blocks by what orbitals their valence electrons or valencies lie in. The s-block contains the initial two groups (antacid metals and soluble earth metals) just as hydrogen and helium. The p-block involves the last six groups, and contains the entirety of the metalloids. The d-block involves the entirety of the transition metals. The f-block, regularly counterbalanced underneath the remainder of the periodic table, has no group numbers and involves the majority of the lanthanides and actinides.
Now, the Electronic configuration of aluminium is $[Ne]3{s^2}3{p^1}$
In the above configuration, the valence electron enters into the p-orbital. So Al is a p-block element.
Hence option D is correct.

Note:
The components from atomic numbers 1 (hydrogen) to 118 (oganesson) have all been found or combined, finishing seven full lines of the periodic table. The association of the periodic table can be utilized to infer connections between the different component properties, and furthermore to anticipate chemical properties and behaviours of unseen or recently discovered components.
