Structure of the Atom Dense nucleus composed of neutrons (0 charge) and protons (+ charge) and surrounded by orbital electrons (- charge). Neutrons and protons firmly held in the nucleus while electrons are very loosely held and are easy to remove. When electrons are removed from the atom‚ two charged particles (ions) are produced the positively charged atom and the negative electron. Energy is absorbed to remove the electron from the atom. Atomic Notation Chemical symbols such as C for

monthly. One is a water usage AVERAGE‚ which is an estimate based on the past year of consumption. One is the ACTUAL METER READING for the previous two months of water usage. The month’s payment is a credit toward the total bimonthly water usage charge. You can tell whether your bill is an averaged bill or a actual meter reading bill by looking in the Meter Reading field (yellow box above) if there is a number in there than you have a Meter Reading bill. If the Meter Reading field is blank and you

Questions: What is the polarity of the resting membrane potential (voltage)? You correctly answered: b. negative What does it mean that the voltage just inside the membrane is negative? You correctly answered: b. There are more negative charges than positive charges just inside the membrane. The membrane of most cells‚ including neurons‚ contains passive‚ open‚ K+ leak channels. Given the normal K+ concentrations and the resultant concentration gradient‚ which direction would K+ be expected to move

| Who Killed The Electric Car | By James Walker | | | | | James Walker STL 100 Who Killed the Electric Car The electric car introduced in 1996 and was popular in California. The car was quiet small and produced no exhaust; it was a product that was loved by consumers and eco-friendly. This idea of the electric car was not one that was recent in implementing; about 100 years ago there were more electric cars than there were gas cars and they ran really well and quiet. The

these collisions build up charges of electricity in a cloud. The positive and negative electrical charges in the cloud separate from one another. When the difference in the charges becomes large enough‚ a flow of electricity moves from the cloud down to the ground or from one part of the cloud to another‚ or from one cloud to another cloud. When the positive charges on the ground leap upward to meet the negative charges‚ the rough downward path of the negative charges suddenly lights up with a

pith balls that were equally charged. They were then constructed into a pendulum using strings. Calculations were done to determine the charge on pith balls‚ calculate the mass of the pith balls and to calculate the electrostatic constant. Experimental Procedure: Using the virtual lab website‚ the ball was charged to 120 by rubbing it against the cat’s fur. The charge was then transferred to the pith balls. The angle was taken using a protractor and the distance between the pith balls was measured
