If you were to separate all of the electrons and protons in 1 g (0.001 kg) of matter, you’d have about 96,000 c of positive charge and the same amount of negative charge. if you placed these charges 4.5 m apart, how strong would the attractive force between them be?

Static electricity usually develops when objects are rubbed against each other. the rubbing process causes some electrons from one of the objects to relocate to the other object. the object that loses electrons then has more protons than electrons and thus develops an overall positive charge. the object that gains electrons then has more electrons than protons and thus develops an overall negative charge. here a balloon is rubbed against a person’s hair. electrons move from the hair to the balloon. the surface of the balloon now has more electrons than protons, so it develops a negative charge. the surface of the hair now has more protons than electrons, so it develops a positive charge. flyaway hair is caused by the fact that each individual strand of hair now has a positive charge. because like charges repel, each piece of hair repels every other piece of hair, making them stand out as far away from each other as possible. what would be good summary of the lab from the information above? a.) static electricity is based off of gravity b.) static electricity is the movement of electrons. electrons will move from the hair to the balloon. c.) static electricity can be created in water. d.) balloons are full of air.

The atom is the basic unit in chemistry. an atom contains neutrons, protons, and electrons. neutrons are neutral, protons have a positive charge, and electrons have a negative charge. most of the time, atoms are neutrally charged, meaning that they have the same number of protons and electrons. sometimes, though, atoms lose or gain one or more electrons, and become positively or negatively charged. a positively or negatively charged atom is called an ion. an ion with more protons than electrons is positively charged. an ion with more electrons than protons is negatively charged. one common ion is a sodium ion, which has a charge of +1. which of the following statements is true? the ion has more protons than electrons. the ion has the same number of protons and electrons. the ion has more electrons than protons.
