So we could oxidize a single atom up to a multi-charged cation.........

$Cu+DeltararrCu^(29+) + 29e^-$

Of course we would need a LOT of energy to do this, and so the equation is (HIGHLY!) physically unreasonable. The ion still has $Z=29$ (manifestly), and this is the smallest such copper particle.

Typical oxidation states of copper are $Cu^(+I)$, and $Cu^(+II)$, $"cuprous"$ and $"cupric"$ ions.

Two of the tenets of the cell theory are: All living things consist of one or more cells, and the cell is the smallest unit of life that displays all of the characteristics of life. Which is the third tenet?

The three basic principles underlying cell theory as we know it today are: All organisms are made of one or more cells. Cells are the basic building blocks of...

What is the smallest particle of an element that retains the properties of that element?

Most can exist as mono-atomic molecules, but some have molecules consisting of more than one atom of the element. Examples are $F_2,Cl_2, Br_2, O_2, N_2, P_4$ An element like sulphur...

Why is the smallest unit that retains the properties of an element?

If you change the atom by changing the number of protons you change the element to another element. Each element has unique properties based on the behavior of the...

What are two physical properties that make metals the ideal material from which to construct electrical wires?

And $"ductility"$ means that the material is capable of being drawn into a wire. And a second property that metallic , metal ions in an electron sea, confers is electrical...

Pure copper may be produced by the reaction of copper(I) sulfide with oxygen gas as follows: $Cu_2S(s) + O_2(g) -> 2Cu(s) + SO_2(g)$. What mass of copper(I) sulfide is required in order to prepare 0.650 kg of copper metal?

You have given the stoichiometric equation that represents reduction of cuprous sulfide: $Cu_2S(s) + O_2(g) rarr 2Cu(s) + SO_2(g)$ Sulfur is oxidized; copper and oxygen are reduced. $"Moles of copper"=(650*g)/(63.55*g*mol^-1)=10.3*mol$....

A student investigated the reactions of copper carbonate and copper oxide with dilute hydrochloric acid. How can a sample of copper chloride crystals be made from copper carbonate and dilute hydrochloric acid?

$CuCO_3(s) + 2HCl(aq)rarrCuCl_2(aq) + CO_2(g)uarr + H_2O(l)$ Or........... $CuO(s) + 2HCl(aq)rarrCuCl_2(aq) + H_2O(l)$ For each acid base reaction the product is the beautiful blue-coloured $[Cu(OH_2)_6]^(2+)$ ion, which is commonly represented...

A compound is broken down into 34.5 g of element A, 18.2 g of element B, and 2.6 g of element C. What is the percent (by mass) of each element?

$%A$ $=$ $(34.5*g)/(34.5*g+18.2*g+2.6*g)xx100%=62.3%$ $%B$ $=$ $(18.2*g)/(34.5*g+18.2*g+2.6*g)xx100%=33.0%$ $%C$ $=$ $(2.6*g)/(34.5*g+18.2*g+2.6*g)xx100%=4.70%$ That is $%" element"$ $=$ $"Mass of element"/"Mass of compound"xx100%$ $"Mass of compound"$ is clearly the SUM of the constituent ....

Copper will react with sulfur to form a copper sulfide, if 1.500g copper reacts with sulfur to form 1.880g of copper sulfide, what is the empirical formula of the copper sulfide?

The idea here is that you need to use the mass of copper and the mass of the copper sulfide to determine how much sulfur the produced compound contains, then...
