Hint: To answer this question, we first need to understand what a periodic table is. The periodic table, commonly known as the periodic table of elements, is a tabular representation of chemical elements organized by atomic number, electron configuration, and recurrent chemical properties. The table's structure reveals periodic patterns.

Complete answer:
This indicates the periodic table block in which the element can be found in the conventional periodic table. S, p, d, and f are the four blocks. The backdrop visuals, periodic tables, and element pages themselves all have color coding for the elements in each block.
s-block – S-block elements are those found in Groups 1 and 2 of the current periodic table. There are two sorts of s block elements: those with one electron (s1) and those with two electrons (s2) in their s-subshell. Hydrogen (H), lithium (Li), helium (He), sodium (Na), beryllium (Be), potassium (K), magnesium (Mg), rubidium (Rb), calcium (Ca), cesium (Cs), strontium (Sr), francium (Fr), barium (Ba), and radium (Ra) make up the S-block (Ra).
p-block – The last electron in a P block element enters one of the three p-orbitals of its appropriate shell. There are six groups of p-block elements since a p-subshell has three degenerate p-orbitals, each of which can accommodate two electrons. Because they have a tendency to lose one electron, P block elements are lustrous and usually good conductors of electricity and heat.
d-block – The elements in the D block are those that can be found in the contemporary periodic table from the third to the twelfth groups. These elements' valence electrons are located in the d orbital. Transition elements or transition metals are other names for D block elements. The 3d, 4d, and 5d orbitals are represented by the first three rows of the d block elements.
f-block - The elements of the F block are classified into two groups: lanthanoids and actinoids. These elements are known as inner transition metals because they provide a transition between the s and d blocks of the periodic table in the 6th and 7th rows. F block elements are those that have their f orbital filled with electrons. These elements have electrons in the f orbital (1 to 14), the penultimate energy level d orbital (0 to 1), and the outermost orbital.
So, we conclude that the 4 blocks of the periodic table are s,p,d and f.

Note:
An element is a pure substance made up entirely of atoms with the same number of protons in their atomic nuclei, as defined by chemistry. Chemical elements, unlike chemical compounds, cannot be broken down chemically into simpler molecules.
