1
New cards
Covalent bond
A bond formed when two atoms share electrons.
2
New cards
Valence Bond Theory
A model that describes covalent bonding as the overlap of singly occupied orbitals from two atoms.
3
New cards
Sigma bond (σ bond)
A type of covalent bond formed by the head-on overlap of atomic orbitals, resulting in cylindrical symmetry.
4
New cards
Bond strength
The amount of energy required to break a bond, measured in kJ/mol.
5
New cards
Bond length
The optimum distance between the nuclei of two bonded atoms where maximum stability occurs.
6
New cards
Overlap of orbitals
The interaction of singly occupied orbitals from two atoms, leading to electron pairing and bonding.
7
New cards
H–H bond
The covalent bond formed between two hydrogen atoms through the overlap of their 1s orbitals.
8
New cards
Energy release in bond formation
The process of forming a bond releases energy, making the resulting molecule more stable than the individual atoms.
9
New cards
Optimum distance between nuclei
The distance where nuclei are close enough to share bonding electrons but not so close that they repel each other.

Energy conversion
1 kJ = 0.2390 kcal; 1 kcal = 4.184 kJ, used for energy measurements in chemistry.
