Answer:
In covalent bonding the two (or more) atoms bonded together share electrons. In ionic bonding, one atom loses one (or more) electrons, while another atoms gains one (or more) electrons.
Step-by-step explanation:
Atoms of molecules and elements come together chemically. The atoms of the same or different elements are joined together by means of chemical bonds, which are of different types depending on how it is formed. These chemical bonds include; covalent bonds, ionic bonds, hydrogen bonds etc.
- Covalent bonding occurs between atoms in such a way that the two or nore atoms involved share their valence electrons. Examples are CO, H2O etc
- On the contrary, ionic bonding also called electrovalent bond, is that type of bonding in which one atom transfers electrons to the other atom. Hence, the atom that loses electrons becomes more electropositive while the atom that accepts electrons become more electronegative. Examples are MgO, CaCl2 etc
