Electric charge

In our time and age, many inventions depend on the use of static electricity such as printers, photocopiers , pollutant removers and even spray painting. Now imagine how our world would differ if we did not have the implementation of static electricity in inventions such as photo copiers or printers. These simple inventions solve big problems. What is static electricity? How do printers work? Why do we need Printers? What are the advantages and disadvantages of the use of printers? These factors…

2. The element being described is Sodium its symbol is Na it has an atomic mass of 22.989769. It has an atomic number of 11. This element has 11 protons, 11 protons, and about 11 neutrons. Protons have a positive charge, electrons have a negative charge, and neutron have a neutral charge. Electron shells are the outer parts of an atom containing the electrons. Valence electrons are electrons in the outermost shell. Valence electrons tell us whether an atom shares, transfers or receives electrons…

Atomic structure AC1.1 1. Produce a table showing each sub-atomic particle with their relative masses and charges (Bbc.co.uk 2015). Particle Relative Charge Relative Mass Proton +1 1 Neutron 0 1 Electron -1 2. Explain the meaning of the terms, ATOMIC NUMBER and MASS NUMBER of an atom in terms of sub atomic particles. The atomic number refers to the number of protons in an atom, the mass number refers to the number of protons plus the number of neutrons (Bbc.co.uk 2015). 3. A…

Electrophysiology involves using electric conductance to measure the electrical activity of cells and tissues in biological samples. It regulates the electrical activity through a change in voltage or electric current. Specifically, in neuronal cells, it helps in the assessment of action potential, long-term potentiation (LTP) and long term depression (LTD)-all of which play an important role in the synaptic activity of the cell. Patch Clamp technique is one of the widely used electrophysiology…

There are countless ways that an iPhone or an iPad can get damaged and while these are great devices that have become practically ubiquitous for anyone who uses them, they are also very prone to damage and it is very important to have the number of iPhone or iPad repairs handy. Here are some common ways that they can get damaged. In the pocket This is a classic way for the iPhone to get damaged. The problem is that the iPhone is constantly being carried on us and that therefore means that it's…

Freshwater creek is a freshwater stream located in North Cairns, and flows through the Redlynch area-which consists of rainforest, housing, farming and recreational areas. In order to have an indication of general health levels for Freshwater creek, measurements of the water parameters must be regularly checked. This is done to maintain health and prevent abnormal water qualities. Certain water qualities like dissolved nitrates, ammonia and oxygen will be measured at a site upstream from…

p-Phenacetin was Hydrochloric Acid, which completely dissociates in water due to it being a strong acid. During this reaction the Hydrochloric Acid proton pronated itself to the amino group in p-Phenetidine, thus giving the amino group a positive charge. Next, a small amount of decolorizing carbon was added to the solution and filtered. The decolorizing carbon caused the solution to turn a dark brown color. The decolorizing carbon absorbed the nonpolar molecules in the solution, that is, the…

He was able to find the charge of an electron with an experiment involving passing oil through an electrically charged plate with a hole in the center. Using this newfound charge and the determined mass-to-charge value of an electron, “you obtain an electron mass of 9.109 x 10-31 kg, which is more than 1800 times smaller that the lightest atom” (Ebbing and Gammon, 47)…

This report will compare the water quality of Freshwater Creek over the last three years using chemistry to show how the three chosen parameters are all linked and affect the overall quality of the water. Water is combination of two atoms, oxygen and hydrogen. When two hydrogen’s bond with one oxygen it makes a covalent bond. A covalent bond relates to the outer shell of electrons (valence shell) being shared with the neighbouring molecule for them to bond. A covalent bond only occurs between…
