metals whose atoms need to “loose” electrons to gain the nearest noble gas configuration and non-metals that need to gain electrons. These electrons are transferred from one atom to another. This gives one ion a positive charge and the other a negative one. The Opposite charges in the ion hold them together in a regular three dimensional lattice by electrostatic attractions; the arrangement of the ions in a crystalline lattice depends on the relative size of the ions. These electrostatic attractions

its nursing and pharmacy departments. Over a 58-day period‚ $16‚800 charges had been lost related to IV solutions not being charged when being administered to the patients. In the nursing department‚ IV solutions are not being properly documented in the Medical Administration Record (MAR). This lack of documentation is not allowing the pharmacy to bill for these IV solutions and the pharmacy is recognizing this as a lost charge. The procedural problem is also causing unnecessary work for the pharmacy

Classifications of the Hybrid Electric Vehicles: The hybrid electric vehicles (HEV) are the special types of vehicles that make use of two things together‚ i.e. conventional internal combustion engine (ICE) and an electric propulsion system‚ which together help in achieving fuel efficiency as compared to any other vehicle. The degree of efficiency and improvement provided by the HEVs depend on the degree and the type of propulsion systems they make use of. The engineers have succeeded in adding

DEMAT In India‚ shares and securities are held electronically in a Dematerialized (or "Demat") account‚ instead of the investor taking physical possession of certificates. A Dematerialized account is opened by the investor while registering with an investment broker (or sub-broker). The Dematerialized account number is quoted for all transactions to enable electronic settlements of trades to take place. Every shareholder will have a Dematerialized account for the purpose of transacting shares. Access

Ion Exchange Chromatography Discussion: The first exercise preformed in this lab was ion exchange chromatography. The purpose of this experiment is to separate molecules based on their differences in charge. Since it is based on charge the amino acids in the cation exchange column‚ if negatively charged‚ flow through the column first because they don’t want to bind to the sodium ions. The positively charged ions will elute last at the highest ph because they bind to the negatively charged beads

Electricity’s impact on Society Electricity has had multiple impacts on society both positve and negative. Electricity has had an effect on everyone in the world‚ even though some people have no understanding or have no use for electricity. For example‚ there are tribes in the Amazon who have never seen a lightbulb who have never beared witness too the heracy of Big brother and yet they are still effected by electricity. The chainsaws which cut down their beloved forests are designed by a man called

and static electricity. ELECTROSTATICS Many of us have this wrong concept in our mind that insulators like plastic and wood cannot carry charges at all. This is a wrong concept. The truth is that most insulators carry a special type of charge which conductors do not carry. The charge is created due to static electricity and is known as an electrostatic charge. We might have heard of the term static electricity but most of the time we dismiss it as a small and unimportant part of electricity. But

structures which means that structure means how a item is put together Contain nucleus‚ which contains protons and neutrons Protons: have an electrical charge and will weigh one atomic mass unit. Neutrons: are chargless. Hence neutral. Will weigh one atomic mass unit. Electrons: will be found moving around the nucleus. Will have a negative charge. Do not have any weight meaning they are weightless and have no atomic mass. Read about Isotopes‚ radioisotopes Molecules/compound Molecules

The super-fast charging device has been dubbed a super capacitor by 18-year-old Esha Khare‚ of Saratoga - as she took home $50‚000 from the Intel International Science and Engineering Fair‚ which took place in Phoenix this week. The device will make waiting hours for a phone to charge a thing of
