no chemical reaction takes place . when electrons are shared it is known as covalent bond
It is not clear from your question what you mean by sharing substances, or exactly what it is that these substances are sharing. However, I'll make a guess. Chemical reactions often involve atoms sharing electrons. And what happens to them during chemical reactions is that the distribution of electrons shifts. Electrons don't have to actually leave one atom and go to another in order to form a chemical reaction. Sometimes it is more a matter of spending some time with one atom and some time with another, or with several others. Electrons are very versatile.
a chemical bond in which valence electrons are shared between atoms giving each of them a full valence shell is a covalent bond.
Sharing of electrons occurs in a covalent bond. In a covalent bond, two atoms share electrons in order to achieve a stable electron configuration. This sharing of electrons results in the formation of a molecule.
This is a covalent bond.
The transfer of electrons in an atom primarily occurs in the outermost shell, known as the valence shell. This region contains the valence electrons, which are involved in chemical bonding and interactions with other atoms. During chemical reactions, these valence electrons can be gained, lost, or shared between atoms, facilitating the formation of ions and molecules.
Electrons are shared in chemical bonding.
All chemical bonding and compound formation occurs from the sharing of electrons.
Valence electrons can be both lost and gained during a chemical reaction, depending on the types of elements involved. For example, in ionic bonding, valence electrons are typically lost or gained to achieve a full outer shell. In covalent bonding, valence electrons are shared between atoms to complete their outer shells.
A chemical change occurs when electrons form a bond between two atoms. This is because the electrons are being shared or transferred between the atoms, leading to the formation of a new compound with different chemical properties.
No, in a chemical bond, atoms share electrons to achieve stability. The sharing of electrons varies depending on the elements involved, and neither atom "owns" the shared electrons. The electrons are shared between the atoms to form a stable bond.
During a chemical reaction, electrons are the subatomic particles that are lost or gained. When an atom loses electrons, it becomes positively charged and when it gains electrons, it becomes negatively charged. This process is responsible for the formation of chemical bonds and the creation of new compounds.

When chemical bonds between atoms are broken, a chemical reaction called a decomposition reaction occurs. In this reaction, the bonds holding the atoms together are broken, leading to the formation of new products. The original reactants are broken down into simpler substances.
The number of electrons lost, gained, or shared by an atom during a chemical reaction depends on its valence electrons and the goal to achieve a stable electron configuration. In ionic reactions, atoms can lose or gain electrons to achieve a full valence shell, while in covalent reactions, atoms share electrons to fill their valence shells.
a chemical bond in which valence electrons are shared between atoms giving each of them a full valence shell is a covalent bond.
Sharing of electrons occurs in a covalent bond. In a covalent bond, two atoms share electrons in order to achieve a stable electron configuration. This sharing of electrons results in the formation of a molecule.
This is called a polar covalent bond
