Why is nickel harder than copper?
Nickel is harder than copper because it has a stronger metallic bond, which means its atoms are more tightly held together. This results in a more rigid structure and greater resistance to deformation, making nickel harder than copper. Additionally, nickel has a higher atomic mass and density compared to copper, further contributing to its hardness.
Why wouldn't Nickel replace copper in copper II sulfate?
Nickel cannot replace copper in copper II sulfate because nickel is higher in the electromotive series than copper.
Is nickel a better conductor than copper?
No, copper is a better conductor of electricity than nickel. Copper has a higher electrical conductivity than nickel, making it a more efficient material for conducting electricity.
How does the nucleus of a copper atom compare to the nucleus of a nickel?
copper has more protons than nickel
How does the nucleus of a copper atom compare to the nucleus of the nickel atom?

What is a 1949 nickel made of?
A 1949 nickel, also known as a Jefferson nickel, is made of 75% copper and 25% nickel. It has a weight of 5 grams and a diameter of 21.2mm.
Is a nickel less dense than a dime?
Both nickels and dimes are composed of Copper and Nickel. A dime, however, is 91.67% Copper and 8.33% Nickel, while a nickel is 75% Copper and 25% Nickel. Since Copper is a bit denser than Nickel, and a dime contains relatively more Copper, than a dime would be denser than a nickel.
What happens when nickel is put in a copper (II) sulfate solution?
When nickel is put in a copper (II) sulfate solution, a displacement reaction occurs where the nickel replaces the copper in the solution. This results in the formation of nickel sulfate and copper metal deposits on the surface of the nickel.
What kind of metal are nickels dimes and quarters made of?
Nickels are made of a mix of copper and nickel, dimes and quarters are made of a combination of copper and nickel with a copper core.
Is nickel a better conductor than copper?
No, copper is a better conductor of electricity than nickel. Copper has a higher electrical conductivity than nickel, making it a more efficient material for conducting electricity.
What is the nickel 5 cents coin made of?
The nickel 5 cents coin is made of a combination of copper and nickel, with 75% copper and 25% nickel. It gives the coin its characteristic silver color.
How does the nucleus of a copper atom compare to the nucleus of a nickel?
copper has more protons than nickel
What is the density of copper nickel?
The density of copper-nickel alloys can vary depending on the specific composition. In general, the density of copper-nickel alloys ranges from around 8.5 to 9.0 grams per cubic centimeter.
What is a 1954 Jefferson nickel made of?
A 1954 Jefferson nickel is made of a combination of metals. It is composed of 75% copper and 25% nickel.
What is an alloy of copper and nickel called?
cupro-nickels, there exists a range of different copper nickel alloys that possess different properties and hence are suited to a range of different applications. Some of the better known copper nickel alloys include: · Copper with 10% nickel · Copper with 30% nickel · Copper with 25% nickel with 0.05-0.4% manganese · Copper with 45% nickel (also known as constantan) All copper nickel alloys consist of only one phase as the copper nickel binary system exhibits complete solid solubility.
