Describe The Number Of Protons And Nuetrons

Copper is a metal, that people obtain from chalcopyrite and bornite ores and minerals, by smelting, leaching and electrolysis, which are chemical reactions. Yet, it belongs to a sub-group of metals called ‘Transition Metals’. Existing as an element, it’s small particles (atoms) are very close to each other (most common state for copper is solid), but aren’t chemically bonded. Consequently, it is a 26th element on the periodic table, meaning that it’s atomic structure consists of 26 protons, and therefore 26 electrons.

The purpose of this lab was to determine the empirical formula of copper oxide compound. In the lab, hydrochloric acid and copper oxide compound was mixed until it formed a blue solution. An oxidation-reduction reaction, a reaction in which there is an exchange of electrons between elements, was performed by adding zinc to the solution to displace the copper in copper chloride. Zinc, in this case, was oxidized by losing two electrons (0 → 2+) while copper was reduced by gaining two electrons (2+ → 0). Also, when the copper was displaced, it became a precipitate, which is a substance that comes out of a solution as a solid due to insolubility.

First a few general informations: Copper has the chemical symbol Cu,an atomic mass of 63.546 and 29 protons. This means that it has also 29 electrons. If 63.546 is rounded to 64 and 29 is subtracted from this, Copper has 35 neutrons. The melting point of copper is 1085 C°.

Did you know the Statue of Liberty is made of copper? The Statue of Liberty is not originally green, it was a dull brown colour but turned green from many years of oxidation.Copper (Cu), Copper’s atomic number is 29 and has the atomic weight of 63.546.Copper is a mineral and an element essential to our everyday lives. It is a major industrial metal because of its high ductility, malleability, thermal, electrical conductivity and resistance to corrosion. It is an essential nutrient in our daily diet. And, its antimicrobial property is becoming increasingly important to the prevention of infection. It ranks third after iron and aluminum in terms of quantities consumed in the USA.Copper has the melting point of 1,981° F (1,083° C) and a boiling

Copper is extracted from chalcopyrite ore, its chemical formula is CuFeS2. Chalcopyrite is a brass-yellow mineral with a chemical composition of CuFeS2. Most sulfide mineral deposits in Australia contain chalcopyrite ore and has been the most valued ore of copper for thousands of years.

The name copper and the symbol Cu derive from the Latin word “Cuprum”, which by definition means the island of Cyprus. Copper is the 29th element and is located amongst the transition metals in the periodic table. Copper is one of the first elements both known and to be utilized by humans. It is believed that the reason for its early discovery was due to the element being able to naturally occur in its relatively pure form. Archaeological evidence has suggested that it was in fact the Mesopotamians somewhere between 5000 and 6000 years ago, which were able to fully utilize both extracting and making use of the element itself. A copper pendant was found in the Middle East and is dated 8700BC. There are many ways that copper can be used, as

it has 2 unpaired electrons in the 4P orbital. in a chemical reaction it is likely to take 2 electrons & become Se-2 or likely to do 2 covalent bond with other atom. it is also likely to lose all 6 electrons in its valence shell & become a +6, or fewer electrons & become +4 or a +2 just as sulfur does above it in the same group.

The experiment was performed to show the many chemical reactions and states of copper, a very common yet important element that can is found in many useful compounds throughout the world. Copper was combined with many different compounds and elements to cause chemical changes in the state of copper. These reactions were conducted to display the several different states of copper throughout the cycle, ultimately restoring the copper after the metal seemingly disappeared.

During lab, we put the metal copper under different circumstances so that we could gain a better understanding as to what goes on in the copper cycle. Throughout each stage of the copper cycle, we deduced what type of chemical reaction took place based on observation, made observations about the state of the metal and what type of environment it was subjected to, and determined what the net ionic equation was for each stage. Following the experiment, we calculated what the percent yield was and compared the changes in mass from the initial stage to the final stage.

There are 29 electrons in the copper atom. There are 29 electrons in copper because copper has to stay neutral, which means that there are also 29 protons. So, since electrons have a negative charge, and protons have a positive charge, 29 negative plus 29 positive equals no charge/neutral. The electron configuration in symbols can be translated by: the first number is the shell number, the letter is the subshell, and the “to the power of,” or superscript, is the number of electrons that are present in the subshell. In the “s” subshell, there is 1 orbital, in the “p” subshell there are 3 orbitals, and in “d” subshells, there are 5 orbitals (“Electron Shell.” Wikipedia). Each orbital can hold a maximum of two electrons. So, the “s” subshell can hold 2 electrons, the “p” subshell can hold 6 electrons, and the “d” subshell can hold 10 electrons. Since there are 29 electrons in copper, all of the orbitals in the subshells will be filled, except there will be one extra “s” subshell if you use 1s2 2s2 2p6 3s2 3p6 3d10 4s1. The fourth shell is the highest shell that contains electrons in copper. So, if you were to add up 4s + 4p + 4d + 4f, it would equal 32 electrons (“Electron Shell.”

Copper is present in body tissue in trace amounts, but the highest amount is found in the liver, followed by the brain, kidney and heart. An adult body contains around 100 mg of copper3.It usually bound to protein complexes; 95% of blood plasma copper is bound to ceruloplasmin, while the rest is bound loosely to other blood proteins such as albumin, transcuperin, and amino acids. However, for a given ceruloplasmin concentration in healthy people, the total copper concentration is varying by 50 µg/dL (8 µmol/L)17.

Copper is a very versatile metal. It is used for very many thing, it’s very ductile so it’s used for wires and electrical work. It is also resistant to corrosion. We also eat it! Copper is a crucial part of our diet to protect us from infection. Copper is an amazing metal and is used for a lot of things, those things include building, electrical, and nutritional value.

Copper has many chemical properties that make it unique. The Atomic number of copper is 29. An Atomic number is a measure of the amount of protons in the nucleus of an atom. Protons are sub-atomic particles, which have a positive charge. The Atomic mass of copper is 63.546. The Atomic mass is a measure of how many neutrons and protons are in an atom. Neutrons are

And copper (II) ions were reduced to copper because it gained electrons and its oxidation number changed from +2 in copper (II) ions to 0 in copper.

The outer shell of electrons that orbit the nucleus of an atom is called the valance shell. This is what makes a copper atom conduct. For a copper atom the number of electrons is one. When a charge of electricity is placed in the end of a wire the electrons move into the wire. Since there is only one electron in the valance shell of a copper atom it can be easily dislodged with a small amount of energy causing it to jump to the next atom. This will then cause the valance electron of that atom to jump to the next atom and so forth. This movement happens very fast making it possible for a large number of electrons to move through the wire. An example of a conductive atom is shown figure 1.
