fluoride LiF Lithium oxide Li2O When naming binary compounds follow these rules: 1. the element with the positive ionic charge is written first. 2. The second word is formed by changing the ending of the name of the element to “ide.” For example‚ bromine changes to bromide. Metals usually have positive charges while nonmetals (when combined with nonmetals) have negative charges. Practice Problems Using the rules given above‚ name the compounds listed in the next column. 1. MgO ____________________

electrically conductive so that it responds strongly to electromagnetic fields. Therefore‚ plasma has properties quite unlike those of solids‚ liquids‚ or gases and is considered a distinct state of matter. Plasma can be accelerated and steered by electric and magnetic fields‚ which allows it to be controlled and applied. Plasma research is yielding a greater understanding of the universe. It also provides many practical uses‚ such as; new manufacturing techniques‚ consumer products‚ the prospect of

Prestige Data Service to its parent company. According to the restriction of the state Public Service Commission‚ the average monthly charge for service by the subsidiary to the parent not exceed $82‚000; therefore the intercompany work was only billed $400 per hour which was not on equal competitiveness with rivals in term of profits. If the subsidiary company charges $800 per hour as commercial sales‚ then the sales revenue and the contribution would largely enhance and make the company profitable

of electricity Conductivity of electricity requires two things‚ charged particles and they have to be freely moving. Metals have free-moving electrons‚ therefore they can carry a charge. Also because these electron Conductivity of Heat In metals‚ not only do the atoms vibrate more when heated‚ but the free electrons charge around more as well. These transfer the energy much faster than just vibrations in bonds. Heat spreads by conduction when atoms increase their vibrations‚ and pass this energy

It is used in the electronics industry by workers working on electronic devices which can be damaged by ESD‚ and also sometimes by people working around explosives‚ to prevent electric sparks which could set off an explosion. It consists of a stretchy band of fabric with fine conductive fibers woven into it‚ attached to a wire with a clip on the end to connect it to a ground conductor. The fibers are usually made of carbon or carbon-filled

Lightning is the energy created by friction from the rise and fall of hot and cold air masses in the clouds. This energy‚ which is only visible as lightning‚ retains a negative charge. To equalize‚ this negative charge must contact a positive charge‚ which is held by ground. The positive charge and the negative charge seek the best route to meet and dissipate; meaning that lightning is only looking for a way to obtain ground. Lightning decides on a target no more than 500 feet prior to striking

distance‚ and second we will look at how the magnitude and sign of the charges affect the force. 2. Theory- As is well known‚ like charges repel and opposite charges attract. That being said‚ the strength of those forces also depends on the distance between the two charges. By observing this force over countless experiments Charles-Augustin de Coulomb discovered an inverse square law relating the force between two charges to the distance between them. This relationship is described by the following
