In general, ionic compounds occur when a metal ion and a nonmetal ion make a compound. When they are a compound, electron(s) are transferred. Ionic compounds will generally conduct electricity as a solution, are brittle, hard, and tend to have high melting and boiling points.
Covalently bonded compounds are generally nonmetal atoms that become a compound, and when they are a compound, they share electron(s). Covalent compounds have low melting points and are poor conductors of electricity (however, an example of something that defies this description is graphite, which is a carbon allotrope that conducts electricity due to electron delocalization).
======================
It is erroneous to say that metal/nonmetal bonds are always ionic, in fact, there are no 100% ionic bonds. Bonding lies along a continuum between 100% covalent and bonds which have a high percent ionic character, but even those have some covalent character as well.
You are better off distinguishing between compounds which exist as networks or lattices and compounds which exist as discrete molecules. Compounds which exist as networks include salts with highly polar bonds, like NaCl, and compounds with high covalent character, like SiO2. These are the ones with high melting points. Diamond and quartz have very high melting points and are very hard and both have very covalent bonds.
Statements like the one above are vast oversimplifications riddled with misconceptions.
In comparison with ionic bonds, the difference in electronegativities of elements in a covalent bond have a lower difference in electronegativities. A covalent bond occurs between two nonmetals that have a difference in electronegativities that is 1.7 or less. Usually an ionic bond has a difference in electronegativities that is greater than 1.7, but not always.
To determine the difference between an ionic and a covalent compound from its chemical formula, you can look at the elements involved. Ionic compounds typically involve a metal and a nonmetal, while covalent compounds involve nonmetals only. Additionally, if the compound contains a metal combined with a polyatomic ion, it is likely ionic.
Silicon compounds can exhibit both ionic and covalent bonding. Compounds such as silicon dioxide (SiO2) have a covalent structure, while compounds like silicon carbide (SiC) can have more ionic character. The nature of bonding in silicon compounds depends on the electronegativity difference between silicon and the other elements involved.
An ionic bond is when one or more electrons are transfered from one atom to another. A covalent bond is when atoms share one or more electrons. The atom Hydrogen would need only 2 electrons but most need 8.
SO2 is not an ionic compound because it is made up of covalent bonds between sulfur and oxygen atoms. In covalent compounds, the atoms share electrons to form bonds, rather than transferring them as in ionic compounds. Therefore, SO2 is considered a covalent compound.

Covalent compounds have lower melting point and boiling point compared to ionic compounds since their intermolecular forces are weak. covalent compounds do not conduct electricity unlike the ionic compounds since they do not have any charged particles They also have strong bonds within the molecules. so they do not react with other compounds easily. Whereas ionic compounds are more reactive.
Types of bonding: ionic (in salts), covalent (in organic compounds), metallic (in metals).
No, esters are covalent compounds having polar character.
Ionic compounds dissociate into their constituent ions when they dissolve in solutions, whereas covalent compounds do not dissociate into ions and remain as molecules. This means that ionic compounds can conduct electricity in solution due to the presence of free ions, while covalent compounds generally do not conduct electricity in solution.
Ionic compounds result from the transfer of electrons between atoms leading to the formation of ions, while covalent compounds form from the sharing of electrons. Ionic compounds tend to have higher melting and boiling points compared to covalent compounds due to the stronger electrostatic forces between ions.
Ionic Compounds are formed by complete transfer of electrons while Covalent compounds are formed by sharing of electrons. Ionic compounds have higher melting points while covalent compounds have lower.
