Is it possible for an object to have more than one type of charge at the same time?

Solutions

Expert Solution

Yes. There can be more than one type of charge on every object. Because both electrons (negative charge) and proton (positive charge) is present in atoms of every object.

But...

There can not be more than one type of NET CHARGE on any object.

Net charge can be either positive (if it has more protons than electrons - excess protons) or net charge can be negative (if it has more electrons than protons - excess negative charge). and if both electrons and protons are equal than that object will be neutral.

All matter is made up of tiny particles. Some of these particles carry bits of electricity called electric charges. Electric charges are responsible for all electrical phenomena. Every substance is made up of tiny particles called atoms. Atoms are made up of protons, electrons, and neutrons. The attraction between protons and electrons holds particles together. An electric charge can be either positive or negative. A positive electrical charge is called a proton. A negative electrical charge is an electron. A neutron has no charge. Negative charges can move freely from one object to another. Protons and neutrons never move from object to object. The energy that comes from these charged particles is called electrical energy.

When the negative charges move to a neutral object, an electric charge builds up on both objects. The first object has an overall positive charge, and the second has an overall negative charge. When an object gains electrons, it has a surplus of electrons and is said to have a negative charge. When an object loses electrons, it has a shortage of electrons, it has a shortage of electrons and is said to have a positive charge. The buildup of electric charges is called static electricity.

If an object is charged with static electricity it has a buildup of electric charges on its surface. If objects have a build up of like charges, they will repel. If objects have a build up of unlike charges, they will attract, or pull toward each other. Charges that build up this way don't stay on the charged object. Sooner or later the charges will move away. When static charges move from an object electric discharge is said to have occurred.

Sometimes more than one atom arrangement is possible, these are called geometric isomers. For the molecules below sketch all the possible geometric isomers. Then keeping in mind that nonbonding pairs on the central atom will try to get as far away as possible from both other bonding and nonbonding pairs, predict which will be the prefferred geometry in nature. Justify your choice. Name the molecular geometry of the prefferred structure. SF4(2 isomers) BrF3(3 isomers) XeF4(2 isomers)
