what makes the electron negative and proton possitive?

Charge is a fundamental property. This means that we simply accept charge as an attribute of the particles. Much like we accept a person's name.\n\nIn other words, we don't know what causes charge in the sense which you inquire to know, but it doesn't prevent us from working with the particles.\n\nCharge aside, electrons and protons are very different particles. Electrons orbit atoms and weight next to nothing, while protons are locked in the nucleus of the atom and are considerably more massive.

electron\nThe electron is a lightweight fundamental subatomic particle that carries a negative electric charge. The electron is a spin-1/2 lepton, does not participate in strong interactions and has no substructure. Together with atomic nuclei, electrons make up atoms; they are responsible for chemical bonding. The flow of electricity in solid conductors is primarily due to the movement of electrons.\nhttp://en.wikipedia.org/wiki/Electron\n\nThe electron, denoted  is a fundamental particle with negative electric charge that is found arranged in quantum mechanical orbits about neutral atoms. The electron is a lepton, and therefore has lepton number 1. The antiparticle of the electron is called the positron. \n\nThe electron mass is  kg, and the electron charge , where  \nhttp://scienceworld.wolfram.com/physics/Electron.html

It is a positive charge, since there is no electron. Often, a naked hydrogen atom also won't have a neutron either, so you will often see the term proton depicted as H+ and vice versa.

I am not sure what you are asking but the answer could be a monoatomic ion. The positive being a cation and the negative being an anion.\n\nYou might ask over at http://forums.mychemistrytutor.com though.

electrons are negatively charged and like charges repel\n\ntherefore, electrons repel\n\nsimilarly protons repel (two +'s)\n\nbut a proton and electron attract, thus causing atoms, and the universe we live in today

Nico, I have no idea what you are talking about.\n\nElectricity is quite simply a movement of electromagnetic charge. Nothing more and nothing less. \n\nAtoms are made up of (amongst other things) protons and electrons. Electrons have a negative electrical charge and neutrons have a positive charge. When an atom has a surplus of electrons it becomes negatively charged and when it has a surplus of protons it has a positive charge.\n\nWhen a charged atom (ion) or even a single electron moves from one place to another that is electricity. \n\nHousehold electricity is a ‘push’ of electrons from a magnetic generator. It exists primarily as a movement of electrons. In contrast the electrical impulses within your muscles and nerves are created by producing a high concentration of metal ions. Such biological electricity exists primarily as a movement of ions.\n\nElectricity isn’t fire or light or anything else in the universe. It is simply what it is, a movement of charge. There really is no other answer.

Because the number of protons is different from the number of electrons.\n\nFor example, the uranyl ion has a total of one hundred eight protons and one hundred six electrons.

When an atom or molecule has the same number of protons and electrons, it is considered neutral.  If it loses electrons (which have negative charge), the particle becomes positively charged.  If it gains electrons, the particle becomes negatively charged.

As an ion, oxygen is negative.  As a molecule, 02 is neutral.  \nAn an ion, hydrogen is positive.  As a moleclue, H2 is neutral.

Electronegativity is a principally the ability of atomic nucleus of the element to attract electrons. Therefore, in a covalent bond, the element (for example oxygen) with a greater electronegativity which has more proton in atomic nucleus will attract more of the shared electrons, thereby creating a negative pole. The other element's ( hydrogen) which has less proton in its naked atomic nucleus has gained transiently positive charge. Its called electropositive. Water molecule is a well known dipole. It consist of electronegative oxygen and electropositive hydrogen atoms. Special bond angles help to create dipole character.

Yes, it does. A negatively charged object is heavier than a positive one. However, this difference is amazingly small that it's hard to even comprehend let alone measure.\n\nEDIT: To the guy below me, although the positron is a recognised particle they do not magically appear to replace a lost electron - a positive object is lighter. See link for a workthrough and proof.

Calling the electron charge negative and the proton charge positive is an arbitrary choice.  Ben Franklin is generally credited with first making that choice for us.\n\nWhy do electrons have charge?  Why do charges experience the forces they experience?  Because that's how God created the universe and its physical laws.  It's fundamental to atomic structure.  If charge didn't exist, or if the forces behaved differently, we wouldn't have the universe as we know it.

The Hydroxide ion has a negative 1 charge due to the fact that the over all ion has an extra electron.\n\nOxygen needs two additional electrons to fill its octet.  Bonding with the Hydrogen provides Oxygen with one, the other electron is picked up from somewhere else to make the over all ion have a charge.

negative and posive are just assumptions and were taken for granted since the time they were mentioned.\n\nbut let me give u silly answer(may be funny also)\n\nelectron is rotation in the orbital and the proton is stable in the nucleus( some people may again contradict me saying that proton is also moving inside the nucleus) \nnow think like this. a person who is content and is positive minded will be stable in this thoughts and deeds.\nbut a person who is fickle and negative minded will be moving without any stability. electron is like the negative minded person. it gets excited easily and goes to higher energy states but returns back losing that energy in no time. it gets attracted to another atom and is seldom stable in its own orbital.\ni think the person who named it , kept this idea in mind.

Don't read too much into this.  The simple truth is that there is no reason, this only convention.  If you want to call protons negative charges and electrons positive charges, that will have absolutely no effect on the science, just as long as you're consistent.  Conventions like this one are set up to alleviate confusion in the community, but there is no greater, cosmic purpose.\n\nYou will run into similar conventions when talking about the sign of electric current (defined as the flow of positive charge, which is counter-intuitive since the electron is conventionally negative and it is the electrons that actually move), the sign of energy differences/heat flow (positive if moving into the system from the surroundings), and several other physical quantities.
