Why are there different blocks in the periodic table?
Based on electron configurations, the periodic table can be divided into blocks denoting which sublevel is in the process of being filled.
What are the 4 sections of the periodic table?
Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals.
What are the 4 sublevels blocks in the periodic table?
Based on electron configurations, the periodic table can be divided into blocks denoting which sublevel is in the process of being filled. The s, p, d, and f blocks are illustrated below.
What block contains all metalloids?
The p-block is home to the biggest variety of elements and is the only block that contains all three types of elements: metals, nonmetals, and metalloids.
What is the block in the middle of the periodic table called?
The transition metalsmake up the middle block of the periodic table. The transition elements or transition metals occupy the short columns in the center of the periodic table, between Group 2A and Group 3A.
Where are the blocks on the periodic table?
The p-block elements are on the right side of the periodic table. They include the last six element groups of the table (except for helium). P-block elements include all of the nonmetals (except hydrogen and helium), all of the metalloids, and the post-transition metals.
What are SPDF blocks in periodic table?
An element block is a set of elements located in adjacent element groups. Charles Janet first applied the term (in French). The block names (s, p, d, f) originated from descriptions of spectroscopic lines of atomic orbitals: sharp, principal, diffuse, and fundamental.
In which periodic block is be?
Location of s, p, d, and f Blocks in the Periodic Table

|---|---|---|
| s block | ||

What are the three special blocks in the periodic table?
A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. The term appears to have been first used by Charles Janet. Each block is named after its characteristic orbital: s-block, p-block, d-block, and f-block.
