Why glass is charged positively when it is rubbed with dry cloth explain whether glass gains or loses electron when it is charged answer?

electrons are stripped away from the atoms in the glass and transferred to the cloth. This leaves the glass with more positive than negative charge, so you get a net positive charge.

What would you use to see if somthing is charged?
an electroscope is used to determine whether an object is charged or not. However, it will not tell if the object is positively or negatively charged.
What is Ballistic galvanometer Explain its construction?
A ballistic galvanometer is used by electricians to measure an electric current. It is commonly used to test whether or not an electric current is present. A ballistic galvanometer consists of a meter that is attached to two probes, one positively charged and one negatively charged. This keeps the user from being electrocuted when an electric charge is present.
Explain how the movement of electrons relates to the concept of potential energy.?
The force acts on the charged particles themselves, hence charge has a tendency to spread itself as evenly as possible over a conducting surface. The magnitude of the electromagnetic force, whether attractive or repulsive, is given by Coulomb's law
How does an electron behave in a magnetic field?
If you wrap a coil of wire around a bar of iron and pass a current, an electromagnet will result. This principle is used in generators where the casing is magnetised and the rotor rotates in the magnetic field inside the casing(the armature), inducing a current in the rotor winding.
What effect does a negative object have on a neutral object?
If the event horizon (space, in this case) of one of the items is breeched by the other and touch, the neutral object becomes negatively charged. If they never touch, they both remain in their present condition. The neutral object's condition will never affect the charge of the negatively charged object, whether they touch or do not touch. The negatively charged item's condition will never change, regardless of physical touch between the two items. ***************Contributed by Czar Acumen*******************
Why does atoms need negative charge?
Atoms by themselves are neutral because they contain an equal amount of electrons and protons. An ion could be negatively or positively charged, depending on whether it lost or gained an electron.
Which term describes the particle that results when an electron is added to an atom?
It depends. If you are talking about electron capture at the molecular level, then when a neutral atom (or molecule) absorbs a negatively charged electron, it becomes negatively charged. All charged atoms (or molecules) are called ions, and a negatively charged ion is called an anion. . If, on the other hand, you are talking about electron capture by the nucleus of an atom, then when a positively charged proton absorbs a negatively charged electron, the proton converts into a neutrally charged neutron and immediately emits a neutrally charged electron neutrino.

Are atoms normally negatively charged?
No, atoms are not normally negatively charged. They are typically electrically neutral, meaning they have an equal number of protons (positively charged particles) and electrons (negatively charged particles). It is possible for atoms or molecules to gain or lose electrons and become positively or negatively charged, but this is not the usual state.

How many electrons must a magnesium gain or lose to achieve electron configuration?
The way the question is worded makes little. A magnesium atom has an electron configuration whether it is negatively charged, neutral, or positively charged.Electron configuration is not a fixed definition that only allows for one certain number of electrons in order for it to "be achieved," simply the fact that it has any electrons at all means it must have an electron configuration.In its neutral state its electron configuration is: 1s22s22p63s2 (or abbreviated: [Ne]3s2).
How might you use a balloon with a negative charge to find out whether the charge on another balloon is positive or negative?
If you move a negatively-charged balloon close to another balloon, if it moves towards the first balloon, it is positively-charged. If it moves away, it is negatively charged.
Is a charge particle because it has more or fewer electrons than protons?
The number of electrons that surround the nucleus will determine whether or not an atom is electrically charged or electrically neutral. The amount of charge on a single proton is equal to the amount of charge possessed by a single electron. A proton and an electron have an equal amount but an opposite type of charge. Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral. On the other hand, if an atom has an unequal number of protons and electrons, then the atom is electrically charged (and in fact, is then referred to as an ion rather than an atom). Any particle, whether an atom, molecule or ion, that contains less electrons than protons is said to be positively charged. Conversely, any particle that contains more electrons than protons is said to be negatively charged.
What does it mean when wires are multicolor?
As a rule, wires are multicolored to indicate whether positively or negatively charged, and/or to indicate how they are routed, especially in situations where many wires are housed in one harness...
What is the basic principle of Isoelectric focusing?
The basic principle of isoelectric focusing is to determine whether molecules are negatively or positively charged. This is something that is extremely imporant when determining charges of specific things.
What would changing the number of electrons change in an atom?
If the number of electrons changes without the number of protons changing, the atom will become an ion, either positively or negatively charged depending upon whether the electron count decreased or increased, respectively.
How do you find if an element is anion or a cation?
An element's number of protons can predict whether it will form a cation or anion. It will form a cation if it has more protons than electrons, or an anion if there are more electrons than protons.
