Covalent Bonding Flashcards

Flashcards on Covalent Bonding

Covalent Bond

A bond formed by the sharing of outermost shell electrons between two atoms.

Covalent Bond (Definition)

The strong electrostatic forces of attraction between the shared electrons and the two positive nuclei of the bonded atoms.

Shared Pair Electrons

Electron pair(s) being shared in a covalent bond.

Lone Pair Electrons

Electron pair(s) that is not involved in the covalent bonds.

Double Covalent Bond

Each oxygen atom shares 2 outermost shell electrons with another oxygen atom, forming a covalent bond.

Triple Covalent Bond

Each nitrogen atom shares 3 outermost shell electrons with another nitrogen atom, forming a covalent bond.

Number of Electrons Contributed for Sharing

The number electrons needed to attain octet / duplet structure.

Strength of Covalent Bond

Triple bond > double bond > single bond

Covalent Compounds

Compounds containing two or more non-metal elements held together by covalent bonds.

Molecule

The smallest part of an element or compound which can exist on its own under room conditions.

Molecular Formula

Shows the actual number of each kind of atoms in one molecule.

Structural Formula

Shows how the constituent atoms are joined up in one molecule.

Dative Covalent Bond (Coordination Bond)

A covalent bond formed between two atoms where both electrons of the shared pair are contributed by the same atom.
