Ion sr2+
Web14 dec. 2024 · Dengan demikian, atom Sr dikonversi menjadi kation Sr2 + divalen (M2 +, seperti sisa logam alkali tanah), isoelektron ke krypton gas mulia. Stronsium kemudian dikatakan memiliki bilangan oksidasi +2. Ketika alih-alih kehilangan dua elektron, kehilangan hanya satu elektron, kation Sr + terbentuk; dan karenanya, bilangan oksidasinya adalah +1. WebLe strontium est l' élément chimique de numéro atomique 38, de symbole Sr. Le strontium, comme le calcium, est un alcalino-terreux. Il est mou, malléable, gris-jaune. Au contact avec l' air, il forme un film d'oxyde protecteur ( passivation ). Il s'enflamme et brûle facilement dans l'air et réagit avec l' eau .
