CHEM 1331 Ch. 2: Atomic Structure & Periodicity 43. The 2s orbital in calcium is more stable (more negative energy) than the 2p orbital even though the 2p orbital has its maximum electron density closer to the nucleus. The reason for this higher stability is a. calcium’s valence orbitals have n = 4 b. the 1s orbital screens the 2- orbital more than the 2s orbital c. due to its greater
Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal , calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. It is the fifth most abundant element in Earth''s crust and the third most abundant metal , after iron and aluminium.
