Electrical and What it is The work of an Automotive Service Technician also known as a Mechanic has changed from normal mechanical repair to a high knowledge and very technical job. Today‚ integrated electronic systems and complex computers run and maintain vehicles. They also measure their performance while on the road and can adjust to certain conditions. Technicians must have a good base of knowledge about how vehicles components work and interact‚ as well as the capability to work with electronic

The element of Nickel is number 28 which means it has 28 electrons and 28 protons (this is the atomic number). The atomic mass of Nickel is 58.71 g.mol^-1 which means that there are 30.69334 neutrons since you subtract the number of protons from the atomic mass to get the number of neutrons. The electronegativity of Nickel is 1.8 on the Pauling scale; this is the tendency of Nickel to attract a bonding pair of electrons. The density of Nickel is 8.9 g.com^-3 at 20°C and the melting point is 1454

The goal of this experiment was to synthesize dibenzalacetone by aldol synthesis. The name ’Aldol synthesis’ was taken from the words ’aldehyde and alcohol’. This is because the product of this reaction contains both an aldehyde and alcohol. The carbon-carbon bond-forming reaction is referred to as aldol addition. An aldol condensation yields many species of products if the reactant is more than one. Therefore‚ the aldehyde has to react with itself to yield one product. Procedure: Followed according

of subatomic particles. The nucleus of an atom is composed of two different types of particles‚ protons and neutrons. Protons are positively charged atoms. The weight of a proton is one amu. Protons are located inside the nucleus and cannot move from inside the nucleus. The proton symbol is . Neutrons are also located inside the nucleus and have a neutral charge. Neutrons are also one amu like protons. Neutrons can move from the nucleus of an atom making an atom an isotope. The neutron symbol is

I was assigned was the element Manganese. The symbol for manganese is Mn. It is number 25 on the periodic table. That means it has 25 protons and electrons even on mars or anywhere you go it will have the same protons and electrons. The atomic number would also be 25. It has 30 neutrons also in in the nucleus. The melting point for Manganese would be 1519 K (1246°C or 2275°F). The boiling point would be 1519 K (1246°C or 2275°F) according to http://education.jlab.org/. It also could be 1245.0 °C

Atoms make up everything around us‚ including ourselves. They consist of protons which give off a positive charge‚ electrons which give off a negative charge and neutrons which have no charge. In an atom there are the same amount of protons as there are electrons. If there weren’t it would cause the atom to behave differently. Atoms have layers around them called shells which contain electrons. Each shell can only hold a certain amount of electrons. Molecules can be multiple atoms of the same element

Recall that isotopes of an element are atoms that have the same number of protons but different numbers of neutrons in their nuclei. Different elements are distinguished by having different numbers of protons. Recall that isotopes of an element are atoms that have the same number of protons but different numbers of neutrons in their nuclei. Different elements are distinguished by having different numbers of protons. The released energy and matter are collectively called nuclear radiation.
