Covalent compounds • Covalent compounds are formed when pairs of electrons are shared between atoms • Only non-metal elements participate in covalent bonding • As in ionic bonding, each atom gains a full outer shell of electrons, giving them a noble gas electronic configuration • Covalently bonded substances may consist of small molecules or giant molecules • When two or more atoms are covalently bonded together, we describe them as ‘molecules’ • Dot-and-cross diagrams can be used to show the electronic configurations in simple molecules • Electrons from one atom are represented by a dot, and the electrons of the other atom are represented by a cross • The electron shells of each atom in the molecule overlap and the shared electrons are shown in the area of overlap • The dot-and-cross diagram of the molecule shows clearly which atom each electron originated from

Covalent compounds

Covalent compounds are formed when pairs of electrons are shared between atoms
Only non-metal elements participate in covalent bonding
As in ionic bonding, each atom gains a full outer shell of electrons, giving them a noble gas electronic configuration
Covalently bonded substances may consist of small molecules or giant molecules
When two or more atoms are covalently bonded together, we describe them as ‘molecules’
Dot-and-cross diagrams can be used to show the electronic configurations in simple molecules
- Electrons from one atom are represented by a dot, and the electrons of the other atom are represented by a cross
- The electron shells of each atom in the molecule overlap and the shared electrons are shown in the area of overlap
- The dot-and-cross diagram of the molecule shows clearly which atom each electron originated from

Why do covalent bonds form only between non metals ?
How does covalent bond differ from ionic bonds?

Replying to

Unlike metals who create a attraction through charges, non metals do not have charges so they share electrons and create a bond, non-metals also want to fill up their last shell so they share electrons
ionic bonds are bonds that have been created from the attraction of charges while covalent bond share electrons to create a bond

Non metals have a higher electronegativity, hence they have a stronger tendency to attract electrons. In contrast metals tend to lose electrons. because of this reason non metals tend to share electrons to stabilize forming covalent bonds

Ionic bonds - tranfer of electrons between atoms. Covalent is like you said shared electrons. Good job !

How does the sharing of electrons in a covalent bond affect the stability of molecules?
What is a polar covalent bond and how does it differ from a nonpolar covalent bond?
Describe the structure and bonding in a molecule of water (H₂O).
What are some examples of molecules that contain covalent bonds?
How do covalent bonds contribute to the formation of giant covalent structures like diamond and graphite?
Explain the concept of a single, double, and triple covalent bond.

it will satisfy the want of the electron shell by sharing electrons
polar covalent bond are not balanced in the sharing of electron while non-polar covalent bond are balanced in the sharing of a electron
2 hydrogen and 1 oxygen ?
mostly non metals like Water molecule
they form structures like diamond and graphite through there attraction
Single covalent bond is between 2 molecules, double is 2 covalent bonds and triple is 3 covalent bonds
