Chemical bonding is very essential for atoms. Take for example: the element carbon. It contains four valence electrons and needs 4 more to make it stable. In order to do that, bonding is needed.
Covalent bonding is applicable to organic compounds while ionic bonding is for inorganic compounds.

No. The noble gasses will not form bonds with most elements and never bond with metals. Metals form metallic bonds with one another, but this is considered a mixture rather than a new chemical compound.
Carbon can form bonds with other elements multiple times, but is most commonly known to form up to four covalent bonds with other atoms. These bonds can be single, double, or triple covalent bonds, depending on the number of electron pairs shared.
Bonds are formed between two atoms because that results in a more stable state for the atoms. This is a result of electron configuration where most atoms want to have 8 electrons in their outer-most orbital (there are exceptions to this rule, however).
Atoms such as carbon, nitrogen, and oxygen often form multiple bonds due to their ability to accommodate additional electrons in their valence shells. These atoms have small energy gaps between their bonding and anti-bonding molecular orbitals, allowing them to form strong multiple bonds. This property is key in the formation of complex organic molecules and in facilitating various chemical reactions.
Atoms of most elements do not exist independently because they are more stable and energetically favorable when they form chemical bonds with other atoms. These bonds allow atoms to achieve a full outer electron shell and attain a lower energy state. This results in the formation of molecules or compounds rather than isolated atoms.
In the most elements that boron form, boron atoms are bonded covalently.
All elements have atoms, but most do not form molecules.
A triple bond is formed between two atoms when they share three pairs of electrons. The most common elements that typically form triple bonds are carbon (C) and nitrogen (N). In a triple bond, there is a sigma bond and two pi bonds holding the atoms together.
Carbon forms covalent bonds in most types of atoms in most cases.
Covalent bonds. Sulfur has a number of allotrpes the most common has 8 sulfur atoms covalently bonded together to form a puckered ring.
The most common form is the single bond, carbon atoms can also form double bonds or triple bonds.

The four elements that form covalent bonds most commonly are carbon, hydrogen, nitrogen, and oxygen. Covalent bonds involve the sharing of electrons between atoms to achieve stability in their outer electron shells.
Any atom can bond to one another, providing that they have space for another bond, because of this, atoms like carbon can have up to 4 bonds between other atoms.
In most cases, covalent bonds are formed between non metal atoms. But there are exceptions such as complexes by d-block metals. An example is diethylzinc.
Carbon can bond with other carbon atoms making long carbon chains. Carbon can form strong pi-bonds allowing for double and triple bonds between carbon atoms as well, and the carbon-carbon pi-bonds can be delocalized for additional stability in rings.
