Electrical Properties Of Metals And Why These Properties Are Important

The students created a macroscopic, three-dimensional (3D) model of several properties of the periodic table. They explained in their own words the following terms: atomic radii, ionic radii, first ionization energy, and electronegativity. Lastly, they identified, described, and explained the patterns observed in the 3D periodic tables for the following element properties: atomic radii, ionic radii, first ionization energy, and electronegativity.

For our science assessment we had the task to research about a metal of our choice. Since I am really into computers, I chose copper. A metal used in all kinds of wires, cpu’s and other stuff without a computer wouldn’t work. This fits really well into what we have to do for the second part, describe how this metal has helped human society.

In the story "Energy story" it talks about the structure of an atom and electrons and how electrons can move easier in somethings than in other things, like in paragraph 21-22 it says that thing like rubber cloth glass and dry air are good insulators, which means that electrons don’t move as well as in things like copper, aluminum, and steel.

In the nucleus of an atom there are protons and neutrons the number of protons and neutrons depends on the element and ,if it is an isotope of that element. E.g. carbon 12, carbon 12 has six neutrons six protons and 6 electrons . Electrons are located around the nucleus of the atom. Electrons are in shells, the shell closest to the nucleus is 1 , the one after 2 and so on. Each shell can only hold up to a certain number of electrons . the first can hold up to 2 , the second 8 (2+6) the third up to 18 (2+6+10). The general formula for finding out how many electrons a shell can hold is 2n^2. Electrons have a negative charge , while protons have a positive and neutrons have no charge. A atom has the same number of protons and electrons. An ion is formed when an atom loses or gains a electrons .

What is an atom? An atom is the basic building block of everything. An atom is made of electrons protons and neutrons and the number of protons determines the element. Back in the 1800’s this whole idea was unknown. In the 1800’s steam was starting to power everything. It became important to know how steam works, so you can learn to use it more effectively. It was this idea that drove Dalton to research the atom.

These electrons, as is the case with the electrons of all atoms, are arranged in a series of shells and subshells. Copper atoms may be described by the symbolic notation, 1s22s22p63s23p64s23d9, where each leading number denotes the shell, the lower-case letter denotes the subshell, and the superscript specifies the number of electrons in the subshell. Within the s-, p-, and d-subshells, there are 1, 3, and 5 orbitals respectively. Each orbital may contain a maximum of 2 electrons. Thus, all orbitals in all the subshells occupied by electrons in the copper atom are full except for one orbital in the d-subshell in the third shell that has just one electron in it. Note that the highest shell containing electrons in the copper atom is the fourth

The atom is a unit of matter, the smallest unit of an element, consisting of a dense, central, positively charged nucleus surrounded by a system of electrons, equal in number to the number of nuclear protons. It consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All electrons bind to the nucleus through an electromagnetic force. A ground of electrons bound together form individual molecules. An atom with an equal number of protons and electrons will hold a neutral charge. An ion has either a positive or negative charge because of a lack of electrons or an electron excess. The number of protons determines the

How atoms make up our very existence is an eye-opener when he explains it as, “…for you to be here now trillions of drifting atoms had somehow to assemble in an intricate and intriguingly obliging manner to create you”. In ‘The Mighty Atom’, Bryson elaborates on the structure of the atom; how protons, the positive particles of the atom uniquely identify every element. The proton’s negative counter parts are the fast moving electrons. After a quick scientific step into the atomic world, Bryson ends with a witty quote ‘Protons give an atom its identity, electrons its

Now that we know how atoms lose electrons, how do atoms gain electrons? When atoms gain electrons it usually has more than 4 valence electrons. This transforms a atom from a neutral state to a negative state therfore turning the atom

In the story “Conducting Solutions”, it explains electric currents, and how energy moves through different kinds of metals and solutions. It also

In a nucleus of an atom consists of protons and neutrons. Number of protons=Number of electrons

Atoms consist of electrons surrounding a nucleus that contains protons and neutrons. Neutrons are neutral, but protons and electrons are electrically charged: protons have a relative charge of +1 and electrons have a relative charge of -1.

• Electric charge is an intrinsic property of the elementary particles that make up atoms. • Atoms • Nucleus consisting of protons (positive charge) and neutrons (no charge) • Electrons (negative charge) orbit the nucleus. • Like charges repel, while opposite charges attract. • Everyday objects have equal amounts of positive and negative charge, so they have no net charge.

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

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.
