What is the name of the collection of elements on the right side of the periodic table with electrons sequentially filling orbitals in their valence?
s-block elements
d-block elements
f-block elements
p-block elements
l-block elements

p-block elements

Explanation:

The periodic table is a display of known chemical elements arranged from left to right as well as top to bottom in the order of increasing atomic number. A total of 118 elements are known till date.

These elements are grouped into 4 different 'blocks'

s-block includes there first two groups on the left of the periodic table- the alkali (group 1) and alkaline earth metals (group 2. Here the s-orbitals get filled up sequentially

p-block includes groups 13-18 except helium. These elements are present on the right side of the periodic table with electrons sequentially filling up the p-orbitals

d-block includes groups 3-12, known as the transition metal series. These elements are present in the center of the periodic table with electrons sequentially filling up the d-orbitals

f-block includes the lanthanide and actinide series also known as inner transition metals. These elements are present in the bottom of the periodic table with electrons sequentially filling up the f-orbitals
