What is a Periodic Table?
The periodic table lists all the elements known to mankind, arranged in order of increasing atomic number and recurrent chemical properties. They are arranged in a tabular format, with a row representing a period and a column representing a group.
In order of increasing atomic numbers, elements are organised from left to right and top to bottom. Thus,
- The valence electron configuration of elements in the same group will be the same, resulting in similar chemical properties.
- Elements in the same period, on the other hand, will have valence electrons in increasing order. Consequently, as the energy level of the atom increases, the number of energy sublevels per energy level increases.
The first 94 elements of the periodic table are found naturally, but the remaining elements (numbers 95 to 118) have only been created in laboratories or nuclear reactors.

Mnemonics for s-Block Elements
S-block elements are those found in Groups 1 and 2 of the current periodic table. There are two types of s-block elements: those with one electron (s1) and those with two electrons (s2) in their s-subshell.
The 14 elements that make up the S-block are hydrogen (H), lithium (Li), helium (He), sodium (Na), beryllium (Be), potassium (K), magnesium (Mg), rubidium (Rb), calcium (Ca), caesium (Cs), strontium (Sr), francium (Fr), barium (Ba), and radium (Ra).

Mnemonics for p-Block Elements
The last electron in a P-block element occupies one of the three p-orbitals of its appropriate shell. There are six groups in p-block elements because a p-subshell has three degenerate p-orbitals, each of which can accommodate two electrons.
Because they tend to lose one electron, P-block elements are shiny and typically good conductors of electricity and heat. In a P-block element like gallium, you’ll find several interesting properties of elements. It’s a metal that can be melted in your palm.
P block elements consist of the following elements:
Group 13 Elements: Boron family
Group 14 Elements: Carbon family

Mnemonics for d-Block Elements
D-block elements are those that are found in the middle of the periodic table, from Group 3 to Group 12. The name d-blocks comes from the fact that the last electron enters the penultimate shell’s d-orbital.
They are known as transition elements because their characteristics fall somewhere in between the highly reactive metallic elements of the s-block and the nonmetallic elements of the p-block. The d-block has four series that correspond to the filling of 3d, 4d, 5d, or 6d orbitals.
- First transition series or 3d series:
Scandium (Sc) ᠆ Sachin
Titanium (Ti) ᠆ Tendulkar

Mnemonics for f-Block Elements
The f-block elements are observed outside at the bottom of the periodic table. The name f- blocks comes from the fact that the last electron enters the anti-penultimate shell’s f-orbital.
Inner transition elements are another name for them. The f block has two series that correspond to the filling of 4f and 5f orbitals.
- Lanthanide series or 4f series
- Actinide series or 5f series
Because the electron is added to the deep-seated f-orbital as the atomic number of lanthanides and actinides increases, the f-block is also known as inner transition metals or elements. For lanthanides and actinides, the outer energy orbital contains 6s or 7s-electrons, while the inner energy orbital contains f-electrons.
- Lanthanide series or 4f series: Rare Earth Metals (Lanthanide Contraction)

Frequently Asked Questions
Q1
How would the tendency to gain electrons change as you go down in a group?
It is predicted to decrease because atomic size increases down the group, and the propensity of the element to gain electrons decreases.
Q2
What were the criteria used by Mendeleev in creating his Periodic table?
Mendeleev devised his Periodic Table based on the fundamental feature of atomic mass as well as chemical property similarities. He focused on the compounds created by elements with oxygen and hydrogen as chemical properties.
Q3
Name three elements that have a single electron in their outermost shells.
Lithium, sodium and potassium have a single electron in their outermost shells.
