They make up the d-block and are the transition elements.
s-block: groups 1 and 2 p-block: groups 13 - 18 d-block: groups 3 - 12 f-block: lanthanides and actinides
Chromium is located in the d-block of the periodic table because it has its outermost electrons in the d orbital. Specifically, chromium has the electron configuration [Ar] 3d5 4s1, which places it in the d-block between groups 3 and 4. This electron configuration gives chromium its unique properties and allows it to form various oxidation states.
The d-block of the periodic table is often referred to as the transition metals. They are:ScandiumTitaniumVanadiumChromiumManganeseIronCobaltNickelCopperZincYttriumZirconiumNiobiumMolybdenumTechnetiumRutheniumRhodiumPalladiumSilverCadmiumLutetiumHafniumTantalumTungstenRheniumOsmiumIridiumPlatinumGoldMercuryLawrenciumRutherfordiumDubniumSeaborgiumBohriumHassiumMeitneriumDarmstadtiumRoentgeniumCopernicium
The d block contains 5 orbitals. Specifically, the d block has five d orbitals that can hold up to 10 electrons.
The d-block elements in the periodic table are located in groups 3 to 12. They are transition metals that have partially filled d orbitals.
The periodic table can be divided into s-block, p-block, d-block, and f-block. These blocks correspond to the elements' electron configurations and help organize the elements based on their outermost electron shells. The s-block includes groups 1 and 2, the p-block includes groups 13-18, the d-block includes groups 3-12, and the f-block includes the lanthanides and actinides.
transition metals or d-block elements
The periodic table is divided into four main blocks: s-block, p-block, d-block, and f-block. These blocks help organize elements based on their electron configurations and properties. The s-block elements are found in groups 1 and 2, the p-block elements are in groups 13-18, the d-block elements are in groups 3-12, and the f-block elements are the lanthanides and actinides. Each block represents a different type of electron orbital and helps to group elements with similar chemical properties together.

The block of the periodic table that is the largest is the s-block, which includes the alkali metals and alkaline earth metals. These elements are located in groups 1 and 2 on the periodic table.
