What are s p d f block elements?

s p d f block elements are the sets of elements grouped by their valence electron orbitals. The four block names are s-block, p-block, d-block, and f-block. Each block indicates which electron sublevel is in the process of being filled. The block names come from the electron azimuthal quantum number values, which represent characteristics of spectroscopic lines: sharp (0), principal (1), diffuse (2), or fundamental (3). G-block gets its name because âgâ is the next letter after âfâ[^1^].

How are s p d f block elements classified?

The s p d f block elements are classified according to their position in the periodic table. The periodic table is a tabular arrangement of all the known elements such that elements with similar characteristics are grouped. The periodic table is made up of horizontal periods and vertical groups[^2^]. Here is how the s p d f block elements are distributed in the periodic table:

• The s-block elements (except for helium) are on the left side of the periodic table. They include the alkali metals (group 1) and alkaline earth metals (group 2). They have ns or ns outermost electronic configuration, where n is the principal quantum number[^2^].

• The p-block elements are on the right side of the periodic table. They include the last six element groups (except for helium). They have ns np outermost electronic configuration. They include all of the nonmetals (except hydrogen and helium), all of the metalloids, and some metals[^2^].

• The d-block elements are the transition metals (groups 3-12). They have (n-1)d ns outermost electronic configuration. They display properties between those of the highly reactive electropositive s-block elements and the more electronegative p-block elements[^2^].

• The f-block elements or inner transition metals are the lanthanides and actinides. They are the two rows of elements found below the main body of the periodic table. They have (n-2)f (n-1)d ns outermost electronic configuration. They display variable oxidation states[^2^].

What are the properties and uses of s p d f block elements?

The s p d f block elements have different properties and uses depending on their type and group. Here are some general trends and examples:

• The s-block elements tend to form soft solids with low melting points. They are electropositive and reactive. They form basic oxides and ionic compounds with nonmetals. They are used in batteries, alloys, fertilizers, fireworks, etc[^2^].

• The p-block elements can gain, lose, or share their valence electrons. They form covalent compounds with other nonmetals and ionic compounds with metals. They have diverse physical and chemical properties. They are used in electronics, medicine, cosmetics, fuels, etc[^2^].

• The d-block elements tend to have high melting points and boiling points. They have multiple oxidation states and form colored complexes and salts. They are good catalysts and conductors of heat and electricity. They are used in jewelry, coins, magnets, steel, etc[^2^].

The f-block elements also have high melting points and variable oxidation states. They form colored complexes and salts, but they tend 04f6b60f66
