Both are transition metals and have a valency of 2.
Nickel and technetium are not similar metals.
Both are transition metals or d-block elements.
Nickel (Ni) and Technetium (Tc) are both transition metals in the periodic table. They are elements that can exhibit multiple oxidation states and are commonly used in various industrial applications, such as in catalysts and electronic devices.

Tc (technetium) and Ni (nickel) are both transition metals. They are located in the d-block of the periodic table and have similar metallic properties such as high electrical conductivity and malleability. Technetium and nickel also have multiple oxidation states due to their partially filled d-orbitals.
