Batteries and Transition Metals

This collection of flashcards covers important concepts related to batteries, corrosion, and transition metals.

Dry Cell

An irreversible primary battery type, such as AA or 9V, with a voltage of 1.5 V.

Lead-Acid Battery

A rechargeable secondary battery with a voltage of 2 V, used in car batteries.

Corrosion

Metal oxidation, a spontaneous process that can result in rust (iron oxidation) and is characterized by the formation of metal oxides.

Electrolysis

A non-spontaneous reaction process powered by electricity, used for plating metals out of solutions.

Transition Metals

Elements typically found in the d-block of the periodic table, known for multiple oxidation states and catalytic properties.

Nickel-Cadmium Battery

A type of rechargeable battery that has a voltage of 1.4 V and is known for its charge memory effect.

Lithium Battery

Highly reliable batteries used in devices like phones and laptops, known for their long lifespan and electronic capacity.

Sacrificial Anode

A method to prevent corrosion by attaching a metal with a lower reduction potential.

Paramagnetism

A property of materials that have unpaired electrons, resulting in weak magnetic attraction.

Lanthanide Contraction

The phenomenon where atomic size of second and third row lanthanides are similar due to poor shielding by f orbitals.

Coordinate Covalent Bond

A bond formed when a ligand donates both electrons to the bond with a metal ion.

Catalyst

A substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
