Atoms have electrons, protons, and (usually) neutrons. Electrons may be shared by or transfered to other atoms. Sharing or transfering protons or neutrons would require a nuclear reaction such as fission, fusion, or radioactive decay.
It is also possible for atoms to share or transfer energy by collision - but I suspect that is not what you meant by your question.
No, in a covalent bond the shared electrons may not always be shared equally between two atoms. Depending on the electronegativity of the atoms involved, one atom may attract the shared electrons more strongly, leading to a polar covalent bond where the electrons are not shared equally.
Shared electrons in covalent bonds are sometimes referred to as bonding electrons. These electrons are shared between two atoms, contributing to the bond formation by holding the atoms together.
Valence electrons are the outermost electrons in an atom and may be involved in chemical bonding with other atoms to form compounds. These electrons determine the reactivity and chemical properties of an element.
If the electrons in a covalent bond are not shared equally, then one atom gets a partial positive charge, and one (the one where the electrons spend most time) gets a partial negative charge. This is a result of differences between the two atoms in their electronegativity values. This then results in what is referred to as a polar covalent bond.
The two main types of bonds formed between atoms are ionic bonds and covalent bonds. An ionic bond is formed when one atom accepts or donates one or more of its valence electrons to another atom. A covalent bond is formed when atoms share valence electrons. The atoms do not always share the electrons equally, so a polar covalent bond may be the result. When electrons are shared by two metallic atoms a metallic bond may be formed. In a covalent bond, electrons are shared between two atoms. The electrons that participate in metallic bonds may be shared between any of the metal atoms in the region.

true
Electrons are shared. they may be shared equally if the elements are nearly equal in electronegativity; a nonpolar covalent bond. Or they may be shared unequally, that is the electrons may spend more time in one atoms orbital than the other atoms orbital(s), if the electronegativity variance is great; a polar covalent bond.
I think it may be covalent.
In a covalent bond, electrons are shared between two atoms to create a stable bond. These electrons are found in the overlapping region of the orbitals of the bonded atoms, forming a "cloud" of electron density that helps hold the atoms together.

In the normal sense of "react", no parts meet: The nuclei remain distinct but electons may be shared.

Covalent bonds involve sharing of electrons. (This contrasts with ionic bonding where electrons are transferred). The bonds may be single (one shared pair), double (two shared pairs), or triple, (three shared pairs). The electrons in a covalent bond may not be shared equally. This is called a polar covalent bond. It odccurs when there is a difference in elctronegativity between the atoms then the more electronegtaive atom has a bigger share. The more electronegative atom has a small negative charge build up and the less electronegative atom a small positive. Usually the electrons are "localised" to the two atoms, however in some compounds such as benzene with alternating double bonds (in the valence bond model) there is resonance and the pairs of electrons in the double bond are spread over the ring.
Just as the valence electrons of atoms occupy atomic orbitals (AO), the shared electron pairs of covalently bonded atoms may be thought of as occupying molecular orbitals (MO).
