How many sublevels are occupied in an atom of sulfur in the ground state?
there is only one unpaired electron in copper
What are the oxidation numbers of copper CuCl?
Oxidation number is the charge per atom in a compound. Cl2= 2- (Cl= 1-) Cu would have to be 2+ to balance the compound, because there is only one copper atom.
Why is one mole of aluminum larger than one mole of copper?
It isn't. The mass of one mole of aluminum is less than the mass of one mole of copper. The number of atoms in one mole of aluminum is the same as the number of atoms in one mole of copper, which is 6.022 x 1023, also known as Avogodro's number.
What is oxidation number of Cu?
If the question is Cu2, then it is equivalent to Cu and the oxidation number for any element is zero. If the question is Cu2+, then the oxidation number is +2.
Is it rare to find a copper quarter?
It is very very rare for a solid copper quarter worth maybe $800 +

Is copper in electrical wiring number one copper?
No, number one copper is used in buss bars. "Number one copper" is a term I am familiar with from recycling copper. It does indeed include buss bars, but also includes any solid wire whose insulation has been removed, or large gauge wire with large strands (as opposed to small gauge stranded wire) whose insulation has been removed. -- Sparkfighter

True. One mole is 6.02x10^23 atoms/items.
What does the roman mean in an ionic compound?
A Roman number in the name of an ionic compound gives the absolute value of the oxidation number of that element in the compound which immediately precedes the Roman number. This is most common with cations of elements, such as copper and cobalt, that can form stable cations in more than one oxidation state. Copper(II) chloride, for example as the formula CuCl2 while copper(I) chloride has the formula CuCl.
