Explanation:
Explanation:
- Electrons are negatively charged particles that orbits the nucleus.
- Chemical and physical properties of elements are usually determined by the number of electrons they posses.
- Electrons are the basis of the chemical changes in which atoms undergo.
- Chemical properties of atoms are a function of the number of electrons they posses.
- When atoms combine, they do so in order to attain stability.
- Combination of atoms involves the loss or gain or sharing of electrons between atoms.
- When atoms combine with one another, they form chemical bonds.
- These chemical bonds can be between two atoms or between molecules.
- The nature of the chemical bonds determines the physical and chemical properties of a host of compounds.
- For example, metallic bonds in metals is responsible for their conductivity and malleability.
- It is also responsible for the wide range of reactions they undergo.
