Atomoic and Sub-atomic Participles, Questions and Answers

b) When popping corn is heated, water inside the kernels becomes a a gas and expands. This creates the pressure to pop a kernel. This is a physical change because the water is just changing state from a liquid to a gas. There is no new substance produced, the popcorn is in a new shape and the water in a new state. Although it cannot be reversed, it can still be a physical

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.

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°.

Copper is formed by the melting and cooling of molten rock and found fairly close to the Earths’ surface, alongside with silver it has sulphite within the ores as they are created in brine which is a boiling salty water deep within the Earths’ crust and then pushed up through ocean vents and create a chimney like effect. Gold is formed through Hydrothermal-hot water-fluids of which are extremely rich in sulphur and found generally near or in

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

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

S.K-2.C.1.1.1 Describe basic changes to properties of matter (e.g., formation of mixtures and solutions, baking and cooking, freezing, heating, evaporating, melting).

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.

Copper is a chemical element that has the symbol Cu and atomic number 29 (Copper Development Association of South Africa, 2017). The element possesses a wide range of properties that make it invaluable for many different applications. It is an excellent conductor of heat and electricity, as well as being very malleable and ductile. Copper also has excellent alloying properties and is resistant to corrosion (Geoscience Australia, 2017). Copper mining is a large industry in Australia, but the industry is under scrutiny for negative impacts on the environments caused by mining.

Copper is the least reactive metal in the experiments because it did not react with any solution.

There are three main parts of an atom, they are the proton, neutron, and electron. The proton and neutron are in the middle of the atom in a nucleus, that's why they're called nucleons. The electron is on the outside around the nucleus, it's a negative charge while a proton is a positive charge and a neutron has no charge. Copper has six isotopes and the atomic number is 29 with the element symbol Cu. Is in group 11 and period 4. Copper is one of the most important metals, it conducts good electricity and heat, it was one of first metals a human ever used. It's also one of the softest and bendable element there is. Isotopes are different from each other depending on the amount off mass. Since the atomic number of copper is 29, it has 29 protons

Copper is a mineral that is essential to our every day life, but only in certain aspects. It is the key to making redox enzymes and hemocyanin. Hemocyanin's are respiratory proteins that use copper binding sites to bind and move oxygen around the body. The enzymes that cause these oxidations are called dehydrogenases. Oxidation-reduction reactions (Redox reactions) must occur together. Because copper is excellent at conducting electricity, engineers make use it in electronics such as smartphones, televisions, computers and etc. Copper is used in the making of coins for a number of countries. Euro coins for example, have copper as their base as copper and its alloys are easily made into coins. Even medical technology requires copper to be able

All the chemical elements are given a unique atomic number; copper is the 29 atomic numbers. Atoms are made of three kinds of smaller particles, called protons, neutrons and electrons the atomic number is the number of protons in the atom. Each element is first identified at room temperature and pressure as being solid, liquid or gas therefore copper is a solid. Elements, like copper, have other properties and characteristics physical properties can be observed and measured whereas chemical properties is how an element reacts with other substances. Copper is capable of being bent and shaped also it can be easily pulled or stretched into thin wire. Copper has a shine to it; it is an excellent transmission of heat and electricity since it is a good conductor. The maximum density of Copper is 8.96 g/cm3.

     Copper is one of the earliest elements known to man. Because of its distinct red color, Copper is very easily identified. In the ancient times, copper could be found lying in the ground in its unattached state without interaction to other substances. Copper and its compounds have many uses in today’s society.
