Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.

Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a silvery-greyish appearance when oxidation is removed.

Symbol Cu A ductile, malleable, reddish-brown metallic element that is an excellent conductor of heat and electricity and is widely used for electrical wiring, water piping, and corrosion-resistant parts, either pure or in alloys such as brass and bronze. Atomic number 29; atomic weight 63.546; melting point 1,085°C; boiling point 2,562°C; specific gravity 8.96; valence 1, 2. See Periodic Table.

A bluish-white, lustrous metallic element that is brittle at room temperature but malleable with heating. It is used to form a wide variety of alloys including brass, bronze, various solders, and nickel silver, in galvanizing iron and other metals, for electric fuses, anodes, meter cases and batteries, and in roofing, gutters, and various household objects. US pennies minted after 1982 consist of a copper-clad zinc core. Atomic number 30; atomic weight 65.38; melting point 419.53°C; boiling point 907°C; specific gravity 7.134 (at 25°C); valence 2. See Periodic Table.

A coin, usually of small denomination, made of copper or a copper alloy.

To coat or treat with zinc; galvanize.

Chiefly British A large cooking pot made of copper or often of iron.

A chemical element (symbol Zn) with an atomic number of 30, a slightly brittle blue-silvery metal.

Any of various small butterflies of the subfamily Lycaeninae, having predominantly copper-colored wings.

(countable) A single atom of this element.

A reddish brown.

(Nigeria) A corrugated iron roof.

A police officer.

A zinc countertop.

To coat or finish with a layer of copper.

(rare) To electroplate with zinc.

(Slang) To bet against, as in faro.

(rare) To coat with sunblock incorporating zinc oxide.

(uncountable) A reddish-brown, malleable, ductile metallic element with high electrical and thermal conductivity, symbol Cu, and atomic number 29.

An abundant element of the magnesium-cadmium group, extracted principally from the minerals zinc blende, smithsonite, calamine, and franklinite, as an easily fusible bluish white metal, which is malleable, especially when heated. It is not easily oxidized in moist air, and hence is used for sheeting, coating galvanized iron, etc. It is used in making brass, britannia, and other alloys, and is also largely consumed in electric batteries. Symbol Zn. Atomic number 30. Atomic weight 65.38.

The reddish-brown colour/color of copper.

To coat with zinc; to galvanize.

Any of various specialized items that are made of copper, where the use of copper is either traditional or vital to the function of the item.

A bluish-white lustrous metallic element; brittle at ordinary temperatures but malleable when heated; used in a wide variety of alloys and in galvanizing iron; it occurs as zinc sulphide in zinc blende

(countable) A copper coin, typically of a small denomination, such as a penny.

A large pot, often used for heating water or washing clothes over a fire. In Australasia at least, it could also be a fixed installation made of copper, with a fire underneath and its own chimney. Generally made redundant by the advent of the washing machine.

(entomology) Any of various lycaenid butterflies with copper-coloured upperwings, especially those of the genera Lycaena and Paralucia.

A police officer.

Made of copper.

Having the reddish-brown colour/color of copper.

To sheathe or coat with copper.

A common metal of a reddish color, both ductile and malleable, and very tenacious. It is one of the best conductors of heat and electricity. Symbol Cu. Atomic weight 63.3. It is one of the most useful metals in itself, and also in its alloys, brass and bronze.

A coin made of copper; a penny, cent, or other minor coin of copper.

A vessel, especially a large boiler, made of copper.

The boilers in the galley for cooking; as, a ship's coppers.

To cover or coat with copper; to sheathe with sheets of copper; as, to copper a ship.

A ductile malleable reddish-brown corrosion-resistant diamagnetic metallic element; occurs in various minerals but is the only metal that occurs abundantly in large masses; used as an electrical and thermal conductor

A copper penny

Uncomplimentary terms for a policeman

A reddish brown the color of polished copper

Any of various small butterflies of the family Lycaenidae having copper colored wings

Coat with a layer of copper

Primarily for galvanizing steel and iron to prevent corrosion.

Copper is mainly used in electrical applications and plumbing, while zinc is used for galvanizing and in alloys.

Yes, both metals are recyclable and retain their properties after recycling.

It plays a vital role in immune function, wound healing, and enzyme activity.

Yes, both metals are found in the Earth's crust and obtained through mining.

Copper ions disrupt microbial cell membranes, effectively killing or inhibiting the growth of bacteria.

Due to its high electrical conductivity, making it efficient for transmitting electricity.

No, because zinc's electrical conductivity is lower than copper's, making it less suitable for such uses.

Yes, while both are essential, excessive intake can lead to health issues, highlighting the need for balanced consumption.

Copper is generally more valuable due to its wide range of applications in essential technologies.

Copper is crucial in renewable energy systems, especially in solar and wind technologies, while zinc is used in batteries and energy storage solutions.

Copper is used in smaller amounts for its essential biological functions, whereas zinc is used to support the immune system and metabolic functions.

Zinc has a lower melting point than copper, affecting their respective uses in industry.

Copper has been used for tools and currency, while zinc compounds have been used in brass and medicinal creams.

Both metals are recyclable and play roles in sustainable practices, though copper's high value encourages more recycling efforts.
