When an object gains or loses electrons it has a?
It's safe to say if an object gains or loses electrons its electric charge has changed. If it was overall electrically neutral before it lost electrons, it would then have a positive charge; if it acquired electrons from initially being neutral, it would have a negative charge. At the atomic level this is called ionization.
What happens to the energy in a solar panel?
Photons of light (energy) are absorbed by the silicon atoms of the solar panel, resulting in an ejection of electrons proportional to the frequency of the photons absorbed. This is called the photoelectric effect. As a large number of electrons are being ejected from atoms and set into motion, this generates an electric current. It is this electric current that can be used to power devices.
What is constrast static electricity?
Electrical current is the flow of electrons. "Static electricity" is more accurately called "static charge". It refers to the build up of a surplus of free electrons on a body (negative charge) , or the withdrawl of free electrons (positive charge). As the word "static" means, these charges are not moving, but are held stationary on the body. The measure of charge is the coulomb, which is 1.24 x 1018 electrons. If a charge is moving along a conductor, always from negative to positive, this flow of electrons is referred to as "current". The basic unit of current, is the amp. 1 amp is charge flowing at the rate of 1 coulomb per second.
What type of particle carries an electric current through a wire?
Electrons being free to move, they carry current through metal. But as electrons have negative charge they move right from negative end to positive end. But conventionally we consider electric current has to flow from +ve end to -ve end. Hence conventional current is always opposite to the direction of flow of electrons.
Does static electricity will transfer by friction conduction or induction?
it is simply Newtons 2nd law, by the stating of protons and electrons being equal
What can you conclude about the orientation of the beam relative to the magnetic field when a beam of electrons passes through a magnetic field without being deflected?
That the beam of electrons were parallel with that of the magnetic field lines.
What is definition of electric current?
Current is the motion of electrons in a conductor being propelled by electromotive force (voltage).
Why does aluminum get hot fast?
Aluminum , being metal, has free moving electrons which transfers heat and electricity very quickly.
What is a fast moving positively charged bit of matter?
With very, very, very high energy, you can get electrons near the speed of light. But they will never reach the speed of light - this is due to them having mass. This is the type of work being done at Accelerator centers like in America (FERMI LAB) and in Europe (CERN). They speed the electrons up to near the speed of light then collide them into each other to learn about these effects of this.
When a battery runs a motor what energy is changed to what energy?
electric to mechanical/kinetic energy the electrons are not actually changed and used, it is important to know that (even if you do, it's worth mentioning if someone happens upon this article and doesn't). The energy that is being converted that is electrical is actually the pushing force on the electrons, the electrons moving through the copper wiring causes magnetic fields to form and creates attraction and displacement inside the motor.
In a circuit how do electronss move?
Because there is a "potential difference" between two ends of a wire (that is like having a battery hooked to, or having it plugged in to a wall outlet) an electric field is established through the wire. electrons respond to electric fields, by moving anti-parallel to them (that is the opposite direction). The electrons in a wire actually move VERY slowly, ~millimeters per second. Because of constant collisions with nuclei the electrons orbit normally.====================================================== In olden days scientists thought that the electric current flows right from the positive polarity to the negative polarity of the battery. Hence this current is said to be the CONVENTIONAL current. But electrons being negatively charged would flow right from the negative to positive. So electrons do flow opposite to the direction of conventional current.
What affect might be caused by electrons being loosely bound to atoms in a material?
1. Chemical bonding 2. Photo electric emission 3. Electric current flow 4. Radiation emission
Why lithium ion is different than a lithium atom?
An ion of any element has a nonzero electric charge while the "normal" atoms of the same element have zero electric charge. Atoms become ions either by losing electrons or by gaining electrons. Lithium (being on the left side of the Periodic Table) will usually tend to lose electrons, becoming positively charged.
What are valence and electrons?
Valence electrons are the ones which participate in chemical reactions in some way, either by moving from one atom to another, or by being shared with another atom. They are found in the outer shell of an atom (there are usually inner shells with other electrons that are not valence electrons, although in the lightest elements, there are no inner shells and all electrons are valence electrons).

What does it mean if atom has a neutral charge?
The term 'neutral charge' is meaningless, if an atom is neutral then it has no charge if it has charge then it can not be neutral. 'Neutral' means that it will not be deflected in an elecromagnetic field. Particles inside atoms are either electrically neutral (neutrons) or are 'charged' (protons and electrons). being charged means that they would be affected by an electrical field. If an electrical field is applied to either protons and electrons, they are deflected in opposite directions. Therefore protons and electrons have opposite charges. The convention is that protons have a '+' charge, and the electrons a '-' charge, although any suitable description (up/down, black/white, left/ght etc) could be used as long as one description was the opposite of the other. All atoms are neutral, as they have the same number of + protons as - electrons in them. If an atom loses or gains one or more electrons it becomes iteslf charged and is then known as an 'ion'.
