How much silver is in a ton of copper?
There are several grades of copper with small additonals of silver in the range of 10 to 28 ounces per ton that are used in electrical applciations where the silver increases the softening tempertaure - - these are useful in some motor or generator applcations where high temperatures would soften high purity copper resulting in some mechanical failure.
What is the atomic number of copper?
Copper. Copper is a chemical element with symbol Cu and atomic number 29. Classified as a transition metal, Copper is a solid at room temperature. H.
What is the best copper compound?
Hydrated copper sulfate (CuSO 4 ·H 2 O), also known as blue vitriol, is the best known copper compound. It is used as an agricultural poison, as an algicide in water purification and as a blue pigment for inks. Cuperic chloride (CuCl 2 ), another copper compound, is used to fix dyes to fabrics.
What is the isotope ratio of copper and lead?
The copper isotope-amount ratio n ( 65 Cu)/n ( 63 Cu) along with the silver isotope-amount ratio n ( 109 Ag)/n ( 107 Ag) and lead isotope-amount ratios n ( 206 Pb)/n ( 204 Pb), n ( 207 Pb)/n ( 204 Pb), and n ( 208 Pb)/n ( 204 Pb) have been used to determine the origin of European coins and the flow of goods in the historical world market. Metals from Peru and Mexico and those from European mining sites have distinct isotopic signatures that enable the origin of the metal to be determined based on the isotopic compositions of silver, copper, and lead in the coins. Silver from mines in Mexico and Peru in the 16 th century was used to mint coins but did not influence the European coin market until the 18 th century [237].

What is the difference between an element and a compound?
The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions. Examples of elements include iron, copper, hydrogen and oxygen.
What is an element made of?
An element is a pure chemical substance made of same type of atom. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule. Elements that compose the compound are chemically combined. Elements contain only one type of atom.
What are allotropes made of?
Allotropes – atoms of an element can form bonds with each other in more than one way leading to difference in their chemical properties. For e.g. carbon binds in a tetrahedron to form diamond and layers of hexagons of carbon forms graphite. Compounds are composed of different elements in a fixed proportion. For example, 1 atom of sodium (Na) ...
What is the atomic number of an element?
Atomic number – the atomic number is denoted by the letter Z and is the number of protons present in the nucleus of the atom of element. For e.g. carbon has 6 protons in its nucleus and for Carbon, Z = 6. Number of protons is also indicative of electric charge or number of electrons present in the nucleus which determines chemical properties ...
What is the valency of an element?
Valency is defined as the number of hydrogen atoms required that can combine with an atom of the element forming the compound. Most compounds can exist as solids (low enough temperatures) and can be decomposed by the application of heat.
How are compounds made?
Compounds are composed of different elements in a fixed proportion. For example, 1 atom of sodium (Na) combines with 1 atom of chlorine (Cl) to form one molecule of sodium chloride (NaCl) compound. The elements in a compound do not always retain their original properties and cannot be separated by physical means. The combining of elements is facilitated by their valency. Valency is defined as the number of hydrogen atoms required that can combine with an atom of the element forming the compound. Most compounds can exist as solids (low enough temperatures) and can be decomposed by the application of heat. Sometimes foreign elements are trapped inside crystal structure of compounds giving them a non homogeneous structure. Compounds are depicted by their chemical formula which follows the Hill system wherein carbon atoms are listed first, followed by hydrogen atoms after which elements are listed in alphabetical order.
How many elements are there in the periodic table?
Elements are listed according to their atomic number on the Periodic Table. Among the 117 known elements, 94 are naturally occurring like carbon, oxygen, hydrogen etc. 22 are artificially produced having undergone radioactive changes. The reason for this is their instability due to which they undergo radioactive decay over a period of time giving rise to new elements during the process like Uranium, Thorium, Bismuth etc. Elements combine in fixed ratios and give rise to stable compounds due to chemical bonds that facilitate compound formation.
Is copper a compound or mixture?
Copper is an element, because it is composed of only one type of atom. A compound consists of two or more elements that are chemically bound together, and a mixture is a physical combination of two or more substances.
