An electron can be gained or lost from an atom for two reasons:
1. A random number of atoms can be close together will have electrons bumping into each other. Since all electrons have a negative charge, they will have magnetic effects on one another, and will push eachother of the outer shell of their atoms and into different ones.
2.Two or more atoms can bond together so that both atoms in turn have a balanced number of electrons.
In normal chemical reactions, electrons are easier to add or remove from an atom. Protons and neutrons are never added or removed in normal chemical reactions. Only nuclear reactions can change the numbers of protons and neutrons, such as radioactive decay. However, even then the protons and neutrons are not added or removed in the way that electrons are.
The ways that a chemical bond to form is for the atoms to either lose or gain their valence electrons.
Chemical bonds form through the sharing or transfer of electrons between atoms. Covalent bonds involve the sharing of electrons between atoms, while ionic bonds involve the transfer of electrons from one atom to another.
The positivity and negativity of an ion is determined by the number of electrons compared to that of protons. If there are more electrons than protons in the ion, it is considered negative. It becomes negative by gaining electrons, which can happen a number of ways. Simply put, most often it gains electrons by pulling them off of other elements and molecules. The more electronegative an element is, the easier it is for it to do this. Elements are most stable in their "octet" configuration where all of the available spots in an orbital are filled. Elements with less than a perfect octet will rip electrons off of other things.
either 3 or 6 depending on how you look at it, neutrons protons and electrons make up an atom, so there are 3. However these particles are divisible into quarks that make them up, there are 6 quarks, up, down, top, bottom, strange and charm, these combine in different ways to give the subatomic particles mentioned in the first part.

Carbon is the "utility player" of chemistry, and can bond in many different ways with other elements. It generally shares electrons covalently with other non-metals, usually hydrogen, oxygen, and nitrogen. It doesn't typically lose or gain them (but can in certain situations.)

You have a misconception about chemical bonding. Electrons do not form bonds with other electrons. As you will recall from Coulomb's Law, electrons repel other electrons since they all have the same negative charge, and like charges repel, while opposite charges attract. So it is the oppositely charged protons to which electrons are attracted. Since atoms contain both protons and electrons, atoms bond with other atoms because the electrons in one atom can be attracted to the protons in a different atom. And there are various types of bonding between atoms. These include ionic, covalent, and metallic.
Chemical bonds form through the sharing or transfer of electrons between atoms. Covalent bonds involve the sharing of electrons between atoms, while ionic bonds involve the transfer of electrons from one atom to another.
First we have to define the word an electron, An electron is negatively charged particle. A metal is a substance consists of number of both electrons and protons. Electrons emitted from the metal surface through different ways such ways as Thermionic, Photoelectric, etc. Free electrons of conductor are electrons emitted from conductor when it disturbed through ways as mentioned above
IF it donates an electron -then atom gains positive charge and if it accepts an electron then it acquires negative charge. the mass of an atom is dependent on protons and neutrons in the nucleus and electrons decide the charge of an atom

Ions are formed when atoms gain or lose electrons. An atom that loses electrons becomes a positively charged ion known as a cation, while an atom that gains electrons becomes a negatively charged ion known as an anion.
Electrons determine the ways in which atoms join together chemically, by forming bonds with other atoms. They also are carriers of electrical energy (current).
