What does a block element mean?

Block are parts of the periodic table in which elements are grouped according to the type of valence orbitals. The valence orbital types s, p, d and f; also gave their names to the blocks in the periodic table, and hence the periodic table; It consists of four blocks, s block, p block, d block and f block.

In which group is SC?

Scandium (from Latin Scandia "Scandinavia") ), is a chemical element with symbol Sc and atomic number 21. It is in 3 in the periodic table. Subgroup (group 3) or scandium group. The soft, silvery-white element is the first of the transition metals and also binds to rare earth metals.

What block are the transition elements in?

group B elements d and f located in the block. or transition metals. they are called inner transition elements.

Is group 5a metal or nonmetal?

Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb) and Bismuth (Bi) consists of elements. The last electron shells contain 5 electrons and their final orbital ends with np3. They usually take -3 valences in their compounds. Nitrogen and phosphorus are nonmetals, arsenic and antimony are semi-metals, bismuth is metal.

In which block is 3A?

Elements in group A in the periodic table are called head group elements. . Elements of group 1A are called alkali metal, group 2A is alkaline earth metal, group 3A is called earth metals, group 7A is called halogens, group 8A is called noble gases.
