A chemical bond is the association of atoms or ions to form molecules, crystals, and other structures. The bond may result from the electrostatic force between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds, or some combination of these effects.
Valence bond theory considers that the overlapping atomic orbitals of the participating atoms form a chemical bond. Because of the overlapping, it is most probable that electrons should be in the bond region. Valence bond theory views bonds as weakly coupled orbitals (small overlap). Valence bond theory is typically easier to employ in ground ...

Metallic bonding is a type of chemical bonding that arises from the electrostatic attractive force between conduction electrons (in the form of an electron cloud of delocalized electrons) and positively charged metal ions. It may be described as the sharing of free electrons among a structure of positively charged ions ( cations ).
The use of games in the chemistry learning process has a positive effect on students’ behaviour, understanding, and interest in the discussed topics. A Chebo Collect (chemical bonding collects) game, which has met validity, practicality, and effectiveness criteria, was used as a medium to learn chemical bonds. This study aimed to assess the ...
One of them is the subject of chemical bonds. The subject of chemical bonds is one of the abstract topics of chemistry, and it is vital for the understanding of many chemical concepts in secondary education and at the university level (Hurst, 2002; Nahum et al., 2006; Nahum et al., 2004; Yayon et al., 2012). Bonding is a central concept in ...
module in teaching chemical bonding concepts using Molview. It was to investigate if there was a significant difference in the chemical bonding concepts knowledge and visual-spatial skills between treatment and control groups of students before and after interventions were carried out.
Chemical bonding of water. Lewis Structure of H 2 O indicating bond angle and bond length. Water ( H. 2O) is a simple triatomic bent molecule with C 2v molecular symmetry and bond angle of 104.5° between the central oxygen atom and the hydrogen atoms. Despite being one of the simplest triatomic molecules, its chemical bonding scheme is ...
