Detailed explanation-1: -In the chemistry of the transition elements, the 4s orbital behaves as the outermost, highest energy orbital. When these metals form ions, the 4s electrons are always lost first, leading to a positive charge on ion.

Detailed explanation-2: -Transition metals are like main group metals in many ways: They look like metals, they are malleable and ductile, they conduct heat and electricity, and they form positive ions.

Detailed explanation-3: -Transition metals have partially filled d orbitals. Transition metals form ions by losing s electrons. Transition metals form multiple ions with different charges.
