What are the covalent bonds and ionic bonds?
Ionic Bonds- When a metal and a nonmetal come together and loses or gains an electron. Covalent Bonds- Two nonmetals that share one or more electrons. Both bonds bonds together to form a stable, complete or filled outer shell of 8 valance electrons.
What are ions and what are the properties of ionic compounds?
When an atom loses an electron, it loses a negative charge and becomes a positive ion. When an atom gains an electron, it gains a negative charge and becomes a negative ion. Ionic bonds form as a result of the attraction between positive and negative ions. When ionic compounds form, the ions come together in a way that balances out the charges on the ions. The chemical formula for the compound reflects this balance. For an ionic compound, the name of the positive ion comes first, followed by the name of the negative ion. In general, ionic compounds are hard, brittle crystals that have high melting points. When dissolved in water or melted, they conduct electricity.
A chemical bond can be defined as a force that?
Chemical bonds are usually either ionic or covalent. Ionic bonds are the bonds that hold ions (which are atoms that are not electrically neutral) together. This usually comes about when one element or compound gives a different element or compound an/some electrons in order to complete an electron shell. This usually occurs between a metal and a non-metal. Covalent bonds on the other hand usually come about through the sharing of electrons, which generally creates much stronger bonds. Unlike ionic bonds, covalent bonds are usually found withing substances containing only non-metals.
Meaning of non bonding electron bond?
As a start: Electrons that are not share between atoms. covalent bonds along with pie bonds require two electrons per bond. the two electrons in the bond are shared electrons or bonding electrons. Atoms such as oxygen and nitrogen have electrons that are not part of a bond. Oxygen is in group VI so it wants to have 6 electrons around it. it gets 2 of its electrons from bonds. the other 4 come from non bonding electrons or two pair of electrons. Nitrogen is in group V so it only wants 5 electrons. Thus, it has three bonds and one non bonding electron pair.
Explain how the properties of ionic and covalent bonds vary?
I'm not totally sure how this helps, but I'll give it my best shot. Ionic and covalent bonds are two different ways that different atoms can be held together in a molecule. As you probably know, most elements have a specific charge relating to their number of valance electrons and, subsequently, their position on the periodic table. Ionic bonds are held together by a fusion of these charges. All atoms naturally want to gain 8 electrons in their outer shell, making their charge zero. Because of this, they will attract eachother based on their charges. For example, hydrogen has a charge of -1 while chlorine has a charge of +1. These two are attracted and become HCl, hydrochloric acid. Because they involve charges, the bonds usually involve a metal and a non-metal. Covalent bonds are a little more tricky. Like ionic bonds, atoms want to complete their outer shell by bonding with other atoms. If the charges do not equal zero, they come together and "share" electrons - the move closer together so they each have 8 electrons in their shell. Covalent bonds are stronger than ionic bonds and hold together most of our polyatomic ions - NO3-, CO3^2-. etc. Covalently bonded molecules can have an overall charge. I hope this helps.
What is quantum of electric charge?
normally it is considered to be the charge on an electron. however quarks come in increments of 1/3 of this charge.

What is the difference between a positron and an electron?
An electron is the carrier of the negative electrostatic force, and it has a charge of -1. Also, the electron, along with the proton and neutron, are the "basic building blocks" of atoms, and they make up the matter all around us. The positron, on the other hand, is an anti-electron - it's antimatter! And it is the antiparticle of the electron. It has a charge of +1, which is just the opposite of the electron's. The fact that the electron and positron are matter and anti-matter, and that they have a charge of -1 and +1 respectively are the major differences. A positron is an electron's anti-particle, and when the electron and positron come in contact with each other to combine, they annihilate each other in a process called electron-positron annihilation. There is a link below to that related question and to a couple of others.
What is the relation with charge on electrons to electron flow in a circuit?
Not entirely sure what the point of the question is, but here are two of the relations between the charge of the electron and electron flow in a circuit; I hope this helps.1. The electron has a negative charge. This is an accident of history; there's really nothing fundamentally "negative" about the electron charge, it's just that some some particles have one kind of charge and others have an opposite one, and the the sign of the charge was assigned before electrons had really been discovered. The choice was arbitrary and could have gone either way, but electrons just happened to end up negative. You can blame Ben Franklin for it. But I digress.Electric current is defined as flowing from positive to negative. If the mobile charge carriers are positively charged, then they are flowing in the same direction as the current. But if the mobile charge carriers are negative - like electrons, which are the carriers in metals - then the carriers are flowing in the opposite direction from the current. In other words, the electrons flow "backwards" because they are negative, because Ben Franklin just happened to write '+' and '-' in the "wrong" places (though he couldn't possibly have known.)2. The electron charge is -1.6×10-19 Coulombs. To put that another way, one Coulomb is about 6.24×1018 electrons worth of charge. Since one Ampere is the flow of one Coulomb of charge per second, it is also a flow rate of 6.24×1018 electrons per second. That's more than six billion billion electrons each second for each Ampere!
What accounts for hydrogen bonds for its extraordinary strength?
Bonds that make-up hydrogen bonds are polar, and therefore, very strong. This gives the hydrogen atom a positive charge that is almost half as large as that of a proton. The small size of the hydrogen atom allows the atom to come very close to unshared pair of electrons on an adjacent molecule.
What is a charged particle?
Any elementary particle with an electrical charge (sort of circular answer); How about ... it's either an electron (negative) or a proton (positive). There are others, but you'll probably never come in contact with them.
Why is it not possible to determine the type of atom by knowing the charge of the atom?
The reason we can't come to any conclusions about what element an atom is by looking at its charge is because there are different elements that could carry the same charge. As a single example, look at any element from the Group 1 column in the periodic table. These elements are the Alkaline Metals, and all of them have a single electron in their valence shell. Their chemical nature is to loan out that electron as soon as possible and take on an "atomic charge" of +1. If you have a given atom with a +1 charge and that's all you know about it, it may be any one of the atoms from Group 1. There are also a number of the so-called transition metals that can take on a +1 charge under certain chemical conditions. All the elements in Group 17, the Halogens, lack one electron from having a full outer or valence shell. They want to borrow an electron from anywhere, and when they do, they take on an "atomic charge" of -1 because of that extra electron. If an atom of some element has a -1 charge because it is "hanging onto" a borrowed electron, it could be any one of the elements in Group 17. By looking at the charge on the atom and nothing else, it isn't possible to determine which atom you're looking at.
Why issue convertible bonds?
Generally, convertible bonds come at a lower cost to the issuer.
How do you add a second wireless control to a PS3?
Your controller should come without any charge, after you have charged the controller it will be connected to the PS3. If you had it with charge for some reason, just connect it to your PS3 with the USB cable.

What happens when you come in contact with high speed electrons from an electron gun?
If you come in contact with high speed electrons from an electron gun, you will get an electrical shock.
What does positive and negative charges make?
They stem from the nucleus of an atom. The atom is composed of electrons, which emit a negative charge, protons which emit positive charges and neutrons which have a neutral charge. When an atom, had a plus positive or minus negative charged, it is called an ion. ion because it either has an extra electron giving it a negative charge, or its missing an electron, giving it a positive charge
