Properties of Transition Metals

These flashcards cover key concepts, definitions, and comparisons between transition metals and alkali metals based on the lecture notes.

Transition Metals

Elements found in the d-block of the periodic table, characterized by their ability to form variable oxidation states.

Properties of Transition Metals

Chemically not very reactive, capable of forming ions with different charges, often form colored compounds, typically high melting and boiling points, high densities.

Ions formed by Transition Metals

Transition metals can form multiple types of ions with varying positive charges, such as Fe2+ and Fe3+.

Alkali Metals

Elements in group 1 of the periodic table that are highly reactive and form single positive ions.

Catalysts

Substances used to increase the rate of a chemical reaction without being consumed in the process.

High melting point (mp) and boiling point (bp)

Characteristic physical property of transition metals, indicating they require high energy to change state.

Density

The mass per unit volume of a substance, transition metals generally have high densities.

Colored compounds

Compounds formed by transition metals often exhibit color due to d-d electron transitions.

Uses of Transition Metals

Commonly used in industrial and chemical processes, including as catalysts.

Reactivity with water and oxygen

Transition metals are less reactive with water and oxygen compared to group 1 metals, requiring higher temperatures for reactions.
