Is copper a member of transition elements?
There are two ions formed by copper. In copper(I) ion, the 3d orbital is fully filled, and show no transitional behaviour. Whereas copper(II) ion shows transitional characteristics as it has unfilled 3d orbitals. Therefore, copper is a transitional element.
What is a rock ball with a crystal filled cavity?
A geode is a rock ball with a crystal-filled cavity. Geodes are typically round or egg-shaped and formed in sedimentary or volcanic rocks. When cracked open, they reveal beautiful crystals inside.
Even though zinc is after copper in the periodic table leading to an increase in the nulear charge by 1 which should therefore decrease the radius why is it larger than copper?
Zinc has a filled 3d sublevel and 4s sublevel. There is more shielding from the effective nuclear charge within the filled 3d sublevel and also from the filled 4s sublevel. Copper does not have a filled 4s sublevel; recall that one of the 4s electrons "jumps up" to the 3d sublevel thereby stabilizing it by making it filled with 10 electrons. Because of this, the 4s is only half filled and there is not as much shielding within the 4s sublevel allowing the effective nuclear charge to pull the 4th energy level in more toward the nucleus. This will make the overall size of the atom smaller.
Nickel and copper lie next to each other on the periodic table how do their structures differ?
Nickel is 3d8 4s2, while copper is 3d10 4s1. If I remember this copper exception to filling its d shell in order correctly the reason is balance in pairs of electrons as the d shell is filled across the row. Chromium is also an exception in this row. ( do not quote me on this, but ask a chemist )
Why is the electron configuration for copper 3d10 4s1 - shouldn't it be 3d9 4s2?
Copper has a partially filled d orbital to achieve greater stability. Hence, it gives up one electron from the 4s orbital to make the 3d orbital completely filled with 10 electrons, which is a more stable configuration. This results in the electron configuration of 3d10 4s1 for copper rather than 3d9 4s2.
Will an electrical circuit with a battery be completed by two copper electrodes in an empty beaker when the beaker is filled with distilled water?
No, distiled water will not conduct electricity.
What does 375 copper filled mean?
"375 copper filled" likely refers to an item that is made with a layer of copper that makes up 37.5% of its composition. This means that the item is not pure copper, but rather copper filled with another material.
Is Daniell cell a fuel cell?
The Daniell cell (Daniel cell) was invented in 1836 by John Frederic Daniell, a British chemist and meteorologist, and consisted of a copper pot filled with a copper sulfate solution, in which was immersed an unglazed earthenware container filled with sulfuric acid and a zinc electrode. As such it is more akin to a battery than a fuel cell.
Is copper a member of transition elements?
There are two ions formed by copper. In copper(I) ion, the 3d orbital is fully filled, and show no transitional behaviour. Whereas copper(II) ion shows transitional characteristics as it has unfilled 3d orbitals. Therefore, copper is a transitional element.
Why does stator water have to be distilled?
It's inpure otherwise Water that is not distilled is filled with diseases or other naughty bad things that we all know is a big no no to drink... Isn't that right bobo? *looks at the bear* Bobo: aaaarrgh

Why would a copper atom lose two electrons to become the copper ii ion when it only needs to lose one and have a full octet?
The Copper (II) ion is formed when a Copper atom loses two electrons because in its neutral state, Copper has a partially filled d orbital, so it is more stable to achieve a fully filled d orbital by losing two electrons. This allows Copper to have a more stable electron configuration similar to noble gases.
What kind of water comes in a car battery?
Car batteries are filled with sulfuric acid, not water. The battery fluids get "topped up" with distilled water if they get low.
Why is shield referred as a mineral storehouse?
because it is filled with minerals like copper, lead, gold, zinc and nickel.
Which of the follwing is an example of a container that is filled with a pure substance rather than with a mixture?
A sealed glass vial containing pure distilled water is an example of a container filled with a pure substance. Since the vial only contains water molecules and no other substances, it is considered a pure substance.
What is the purpose of the water reservoir in an iron?
The purpose of the water reservoir in an iron is to reduce the mineral buildup on the iron as well as on the clothes. It is used by simply being filled with distilled water.
Is drinking crystal light is as good as drinking water?
it is not because half the entire thing is just filled with sugar and it stains your carpet.
