In the modern periodic table, the block indicates the value of `………………` for the last subshell that received electrons in building up the electronic configuration. Fill in the blank with appropriate option

A

Atomic number

B

Aximuthal quantum number

C

Principal quantum number

D

Atomic mass

Text Solution

Verified by Experts

The correct Answer is:
2
The block indicates value of azimuthal quantum number `(l)` for the last sub`-` shell that received electrons in building up the electronic configuration. For examples group 1 and group 2 elements belong to `s-` block as last electron enters in `s-` subshell.

In the modern periodic table, elements are arranged in order of increasing atomic numbers, which is related to the electornic configuration. Depending upon the type of orbitals receiving the last electron, the elements in the periodic table have been divided into four blocks, viz, p,d and f. The modern periodic table consists of 7 periods and 18 groups. Each period begins with the filling of a new energy shell. in accordance with the Aufbau principal, the seven periods (1 to 7) have 2,8,8,18,18,32 and 32 elements respectively. The seventh period is still incomplete. To avoid the periodic table being too long, the two series of f-block elements, called lanthanoids and actinoids, are placed at the bottom of the main body of the periodic table The last element of the p-block in 6th period is represented by the outermost electronic configuration
