8.1: Chemistry of the Transition Metals - Chemistry LibreTexts
A transition metal is one that forms one or more stable ions which have incompletely filled d orbitals.On the basis of this definition, scandium and zinc do not count as transition metals - even though they are meers of the d block.. Scandium has the electronic structure [Ar] 3d 1 4s 2.When it forms ions, it always loses the 3 outer electrons and ends up with an argon structure.
Acid and Metal Word Equations Chemistry Tutorial

WebElements Periodic Table » Calcium » reactions of elements
Calcium is a silvery white metal. The surface of calcium metal is covered with a thin layer of oxide that helps protect the metal from attack by air, but to a lesser extent than the corresponding layer in magnesium. Once ignited, calcium metal burns in air to give a mixture of white calcium oxide, CaO, and calcium nitride, Ca 3 N 2. Calcium
