Indeed, lanthanum is a strongly electropositive metal, comparable to calcium in electropositivity.
3.
OgF 2 is predicted to be partially ionic due to oganesson's high electropositivity.
4.
Caesium has the highest electropositivity of all non-radioactive elements and fluorine has the highest electronegativity of all elements.
5.
It was determined that Group I, II, III, and Lanthanide metals all produced rousing responses, but the average score generally increased with electropositivity.
6.
While electronegativity increases along groups, electropositivity " decreases " along periods ( from left to right ) and " increases " down groups.
7.
The impermeability of the oxide layer of thorium contrasts with that of the later actinides and conforms to the trend of increasing electropositivity and reactivity as the actinide series is traversed.
8.
The driving forces for electron donor and acceptor behavior in chemistry is based on the concepts of electropositivity ( for donors ) and electronegativity ( for acceptors ) of atomic or molecular entities.
9.
Due to the large ionic radius and great electropositivity of La 3 +, there is not much covalent contribution to its bonding and hence it has a limited coordination chemistry, like yttrium and the other lanthanides.
10.
These facts, combined with some elements almost always having certain oxidation states ( due to their very high electropositivity or electronegativity ), allows one to compute the oxidation states for the remaining atoms ( such as transition metals ) in simple compounds.
