In chemistry the name given to a charged atom is?
Ion... Anion, negative charge... Cation, positive charge
How do you work out specific charge?
To work out the specific charge of a given element, you will take the positive electron charge and multiply it by the negative electron charge. This can be calculated by the formula q=ne
What minimum amount of charge can be given to any object?
The minimum amount of charge that can be given to any object is the charge of an electron, which is approximately ( -1.6 \times 10^{-19} ) coulombs. This is considered the fundamental unit of charge in physics.
What happens to a capacitance if the plates have a charge that is doubled?
The capacitance won't change, or it won't change significantly. The capacitance is simply the charge/voltage ratio - and if the charge doubles, the voltage will also double. Capacitance is determined by the physical properties of the capacitor (plate separation, plate area, and dielectric). The unit for capacitance (farad) is a coulomb per volt. So the capacitance is the amount of charge (coulombs) that the plates will hold at a given voltage.
Will a device still charge if it needs 1.58 amps but it is given 1.28?
Yes, it will just take longer to charge.
What will happen when soap bubble is given negative charge or electrons.?
When a soap bubble is given a negative charge or electrons, the repulsion between like charges will cause the bubble to expand and its surface area to increase. This is because the excess negative charge will spread out to try to minimize the electrostatic potential energy. If the charge is strong enough, the bubble may eventually burst due to the increased surface tension caused by the repulsion between the excess electrons.
Is it possible for charge density to be negative?
Yes, it is possible for charge density to be negative. Charge density refers to the amount of electric charge per unit volume, and it can be negative if there is an excess of negative charges in a given volume.

Ion... Anion, negative charge... Cation, positive charge
What kind of charge does an object have when it has given away electrons?
negative
A metallic coin is given a negative electric charge How does its mass change?
its mass will increase by an amount too small to measure directly
How does the electric field direction change from positive to negative in a given system?
In a given system, the electric field direction changes from positive to negative when the source of the electric field changes its charge from positive to negative.
How do you work out charge?
To work out the specific charge of a given element, you will take the positive electron charge and multiply it by the negative electron charge. This can be calculated by the formula q=ne
How is an atom given a neg charge?
In simple terms, an atom is made up of Protons, Neutrons, and Electrons. Protons have positive charge (+1), Neutrons have no charge (0), and Electrons have negative charge (-1). If an atom gains or loses Electrons, it's net charge changes. To result in a negative charge, the atom must have more Electrons than Protons.
The electric field of a point charge always points away from the charge?
If the given point charge is of positive one then the field points away from the charge. This is because we define the field at a point as the FORCE acting on unit POSITIVE charge. Like charges have to repel and hence the direction. If, other wise, the point charge is negative then electric field due to this negative charge would be towards the negative and not away from it.
What is Grazing Incidences and Grazing Emergent?
two identical metal masses are taken one is given a positive charge and the other an equal negative charge .will their mass changes?
What is the physical meaning of charge density on lines or on areas?
Every object consists of a certain amount of positive charge and a certain amount of negative charge. For neutral objects, the amount of each type of charge is equal in every tiny, or infinitesimal, portion of the object. If the object has the shape of a line, the amount of positive charge in each tiny segment of length along the line is equal to the amount of negative charge in each tiny segment of length. For a neutral three-dimensional object, such as a cube, the amount of negative charge in each small volume element of the total volume of the cube is equal to the amount of positive charge in each small volume element. All neutral objects have a charge density of zero throughout their volumes despite the fact that they have charge. The charge density describes the amount of excess charge per given region of space. For objects that are not neutral, then, the charge density is either positive or negative. A positive charge density expresses the fact that an object has a given amount of positive charge more than it has negative charge in a specific region of space. Likewise, a negative charge density means the object has a given amount of negative charge more than positive charge for a given region of space. For a line of charge, the charge density is expressed as Coulombs per meter when using SI units. For a two-dimensional object, such as a disk, the charge density using SI units is Coulombs per (meter^2). For objects that have uniform excess charge throughout their volume, the charge density is expressed as the total amount of excess charge on the body divided by the total length/ area/ volume of the body. For objects that have nonuniform charge excesses, the charge density must be expressed as a function of position (and possibly, time) within the object.
What is an atom that has given up or gained electrons?
Atoms that have lost or gained one or more electrons are called ions.An atom that has gained and electron is an anion; and atom that has lost an electron is a cation. Gaining an electron means the anion has a negative charge; losing one or more electrons means the atom has a positive charge.
