Which of the following options are all transition metals?

Correct option is B

The correct answer is (b) Cu, Fe, Ni, Ti.
· Transition metals are elements found in groups 3 to 12 of the periodic table and are characterized by having an incomplete d-subshell.
· Cu (Copper), Fe (Iron), Ni (Nickel), and Ti (Titanium) are all transition metals.
· They exhibit properties such as the ability to form various oxidation states, the presence of colored compounds, and catalytic behavior.
Information Booster:
· F, Cl, Br, I: These elements are halogens, not transition metals.
· He, Ne, Ar, Au: He, Ne, and Ar are noble gases, while Au (Gold) is a transition metal.
· Na, Mg, Al, Mn: Na (Sodium) and Mg (Magnesium) are alkali and alkaline earth metals, respectively. Al (Aluminum) is a post-transition metal, while Mn (Manganese) is a transition metal.
