S-Block Elements

Consisting of the first two groups, S-block elements have quite similar physical and chemical properties. The valence electrons of the elements in this block occupy s-orbitals.
Group 1 is known as alkali metals. It includes Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Ru), Caesium (Cs), and Francium (Fr).

P-Block Elements

Consisting of last six groups of the periodic table (Groups 13 to 18), P-block elements have their valence electrons occupying p-orbitals.  This block consists of non-metals, semi-metals and poor metals.
Group 13 is known as Boron group or the group of Icosagens or Triels. It includes Boron (B), Aluminium (Al), Gallium (Ga), Indium (In), and Thallium (Tl).

Group 17 is known as the group of Halogens. It includes Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I), and Astatine (At).
Mnemonic for Group 17: Fir Call kar Bahaar AayI Aunty.

Group 18 is known as the group of Noble gases, excluding Helium. Normally, they are all odorless and colorless gases with very low chemical reactivity. The group includes Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and the radioactive Radon (Rn).
Mnemonic for Group 18: He Never Arrived; Kara Xero Run pe out.

D-Block Elements

D-Block elements consist of element groups 3 to 12 that correspond to the filling of the d-orbital subshell of the second outermost shell. Groups 3 to 11 are also known as transitional metals. Group 12 elements, which have its d subshell completely filled, are also known as post-transition elements.
D-block elements and F-block elements show considerable similarities across the periods too.
We can memorize these elements across the periods:
Period 4 elements are quite stable and many of them are very common in earth’s crust or core or both. D-block elements it includes are Scandium (Sc), Titanium (Ti), Vanadium (V), Chromium (Cr), Manganese (Mn), Iron (Fe), Cobalt (Co), Nickel (Ni), Copper (Cu) and Zinc (Zn).

Read as: Science Teacher Vineeta Kriplani manfenko ni kyun zaan hai?

Period 5 elements are known to fill their 5s shell first, then 4d shells and then 5p shells, with rhodium being the exception. The elements of this period show many exceptions to Maledung rule. D-block elements it includes are Yttrium (Y), Zirconium (Zr), Niobium (Nb), Molybdenum (Mo), Technetium (Tc), Ruthenium (Ru), Rhodium (Rh), Pd (Palladium), Silver (Ag) and Cadmium (Cd).

Period 6 includes the lanthanides or rare earths. Some of these transition metals are very valuable such as gold. D-block elements it includes are Lutetium (Lu), Hafnium (Hf), Tantalum (Ta), Tungsten (W), Rhenium (Re), Osmium (Os), Iridium (Ir), Platinum (Pt), Gold (Au) and Mercury (Hg).

Read as: La Hafta Warna Reh Us Irritating Popat ke saath Aur Hoja pagal.

Period 7 contains the radioactive elements only. It includes actinides which include the heaviest naturally occurring element Californium. All other elements are synthesized artificially. D-block elements.
it includes are Actinium (Ac), Rutherfordium (Rf), Dubnium (Db), Seaborgium (Sg), Bohrium (Bh), Hassium (Hs), Meitnerium (Mt), and Darmstadtium (Ds).

F-Block Elements

F-block elements have their valence electrons in f-orbitals. They are also known as inner transition elements. They can be divided into Lanthanides (also known as rare earth elements) and Actinides that are highly reactive to halogens and chalcogens like lanthanides but they react more easily.|
Lanthanides include Cerium (Ce), Praseodymium (Pr), Neodymium (Nd), Promethium (Pm), Samarium (Sm), Europium (Eu), Gadolinium (Gd), Terbium (Tb), Dysprosium (Dy), Holmium (Ho), Erbium (Er), Thulium (Tm), Ytterbium (Yb) and Lutetium (Lu).
