Chemical bond. Covalent bonding of two hydrogen atoms to form a hydrogen molecule, H. 2. In (a) the two nuclei are surrounded by a cloud of two electrons in the bonding orbital that holds the molecule together. (b) shows hydrogen's antibonding orbital, which is higher in energy and is normally not occupied by any electrons.
A quadruple bond is a type of chemical bond between two atoms involving eight electrons. This bond is an extension of the more familiar types of covalent bonds: double bonds and triple bonds. [ 1] Stable quadruple bonds are most common among the transition metals in the middle of the d-block, such as rhenium, tungsten, technetium, molybdenum ...
Ionic bonds have high bond energy. Bond energy is the mean amount of energy required to break the bond in the gaseous state. Most ionic compounds exist in the form of a crystal structure, in which the ions occupy the corners of the crystal. Such a structure is called a crystal lattice. Ionic compounds lose their crystal lattice structure and ...
Molecular geometry. Geometry of the water molecule with values for O-H bond length and for H-O-H bond angle between two bonds. Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths, bond angles, torsional angles and any other ...
The Chemical Bond. DeKock, Roger L. Journal of Chemical Education, v64 n11 p934-41 Nov 1987. Discussed and described are several types of chemical bonds: (1) ionic bonds; (2) covalent bonds; (3) hydrogen bonds; (4) bonds in the solid state; and (5) variation in bond strengths. (RH) Discussed and described are several types of chemical bonds: (1 ...
Ion. Electron transfer between lithium (Li) and fluorine (F). Forming an ionic bond, Li and F become Li + and F − ions. An ion ( / ˈaɪ.ɒn, - ən /) [1] is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton ...
Orbital hybridisation. In chemistry, orbital hybridisation (or hybridization) is the concept of mixing atomic orbitals to form new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) suitable for the pairing of electrons to form chemical bonds in valence bond theory. For example, in a carbon atom which ...
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 ...
