Vor 2 Tagen · All but one of the lanthanides are f-block elements, corresponding to the filling of the 4f electron shell. Lutetium is a d-block element (thus also a transition metal ), [6] [7] and on this basis its inclusion has been questioned; however, like its congeners scandium and yttrium in group 3, it behaves similarly to the other 14.
Vor 3 Tagen · Amino acids can be classified according to the locations of the core structural functional groups (alpha- (α-), beta- (β-), gamma- (γ-) amino acids, etc.), other categories relate to polarity, ionization, and side chain group type (aliphatic, acyclic, aromatic, polar, etc.).

Vor 3 Tagen · F-16 Block 70/72 updates improve structural, combat, and safety features, extending service life by 12,000 hours. Combat efficiency enhancements include AESA radar and digital radar warning receiver interface.
Vor 5 Tagen · The elements in the long form of periodic table are classified into four blocks. They are s, p, d and f-block elements. The classification is based on the name of orbitals which receive the last electron. The elements in which the valence shell electron enters the s-orbital are called s-block elements. For example let us take sodium.
