Solution

Charged atom:Any atom that bears charge is called charged atom or ions. Charged atoms are formed by the loss of electrons or gain of electrons by a neutral atom.Types:If it is positively charged or has a positive charge then it is called cation i.e, Na+,K+ etc.If it is negatively charged or has a negative charge then it is called an anion .i.e, Cl-,F-,etc.Cations are formed when a neutral atom loses its one or two electrons.Anions are formed when a neutral atom gains one or two electrons from another atom.

Solution

The correct option is B ionAn atom which carries a charge is called an ion. Ions can be positively or negatively charged. For example, Na+ is a positive ion formed by losing an electron and Cl− is a negative ion formed by gaining an electron.

Answer

Verified

Hint: Usually the charge of an atom will indicate the oxidation state or valence electron of the atom. If the outermost shell is completely filled or half – filled, then the atom becomes highly stable. The most common charges are always equal to the maximum stability of the atom. And the charge is a preserved property of definite subatomic particles.

Complete answer:
As we know that a charged atom is known as an ion. And the charges may be positive or negative. The atom contains three subatomic particles, which are protons, neutrons and electrons. The neutrons and the protons are located inside the nucleus. But the electrons are bound around the nucleus in an orbital. The number of electrons and protons are the same. The neutron does not have any charge. And the charge of protons is equal to positive and the electrons have a negative charge.
If two atoms formed by an ionic bond, loss or gain of valence electrons takes place to obtain the stable electronic configuration. If the atom loses the electrons, there is a formation of ions with positive charge. And if it gains the electron, it attains the negative charge. The ion with positive charge is known as cation and negatively charged ion is known as anion.

Note:
We have to remember that the charge is a physical property and it is responsible for the force present in an electromagnetic field. And it is a physical property which is present in an element and it will attain by a force when the matter undergoes any reactions like gaining or accepting the electrons. The charges are mainly in two types which are positive charge and negative charge. Same charges will always repel each other and the unlike charges will always attract each other.

Overview of Atomic Electrical Charges

Atoms, the fundamental building blocks of all molecules, consist of three types of particles: protons, neutrons, and electrons. Of these three subatomic particle types, two (protons and electrons) carry a net electric charge, while neutrons are neutral and have no net charge.

Both protons and electrons have charge that is quantized. That is, the magnitude of their respective charges, which are equal each other, is 1. This standard value is equal to approximately 1.6×10-19 Coulombs.

Protons

Protons are found in the center of the atom; they, with neutrons, make up the nucleus. Protons have a charge of +1 and a mass of 1 atomic mass unit, which is approximately equal to 1.66×10-24 grams. The number of protons in an atom defines the identity of the element (an atom with 1 proton is hydrogen, for example, and an atom with two protons is helium). As such, protons are relatively stable; their number rarely changes, only in the instance of radioactive decay.

Electrons

Electrons are found in the periphery of the atom and have a charge of -1. They are much smaller than protons; their mass is $\frac{1}{1836}$ amu. Typically in modeling atoms, protons and neutrons are regarded as stationary, while electrons move about in the space outside the nucleus like a cloud. The negatively charged electronic cloud indicates the regions of the space where electrons are likely to be found. The electrons cloud patterns are extremely complex and is of no importance to the discussion of electric charge in the atom. More important is the fact that electrons are labile; that is, they can be transferred from one atom to the next. It is through electronic transfer that atoms become charged.

Ions

In the ground state, an atom will have an equal number of protons and electrons, and thus will have a net charge of 0. However, because electrons can be transferred from one atom to another, it is possible for atoms to become charged. Atoms in such a state are known as ions.

If a neutral atom gains an electron, it becomes negative. This kind of ion is called an anion.

If a neutral atom loses an electron, it becomes positive. This kind of ion is called a cation.

The steady flow of electrons is called current. Current is what flows through electrical wires and powers electronics items, from light bulbs to televisions.

Planetary Model of an Atom

Small electrons orbit the large and relatively fixed nucleus of protons and neutrons.
