1.2.4.1Covalent bond Thecovalent bondimplicates the strongest bond in the realm of ligand–receptor interactions. Such a bond is formed by the share of an electron from each of the two participating atoms. In case of drug-receptor interaction, the electrons are shared by atoms of the ligand ...
dative covalent bond例子 Dative covalent bonds, also known as coordinate bonds, occur when one atom donates a pair of electrons to another atom. Here are a few examples: 1. Ammonia (NH3): In ammonia, the nitrogen atom donates a pair of electrons to a hydrogen ion (H+) to form an ...
How many valence electrons does nitrogen have? How many valence electrons does seaborgium have? How many electrons can the innermost shell of an atom have? How many valence electrons are in a stable ion of a period 4 metal? How many valence electrons does lead h...

Formation of Nitrogen molecule is an example of Triple covalent bond. Atomic number of nitrogen is 7.That means Nitrogen atom contains 7 protons in its nucleus, 2 electrons in its first shell and 5 electrons in second shell. Nitrogen atom requires 3 more electrons to attain stable electronic ...
Sigma bond is stronger bond than the Pi-bond. If atomic orbitals overlap about the nuclear axis then sigma bond is formed but when atomic orbitals overlap sideway then Pi-bond is formed. Compound having maximum bond angle is : View Solution ...
For a nitrogen atom to attain a stable octet electronic configuration, it needs three more electrons. A nitrogen atom can share its three valence electrons with another nitrogen atom. In doing so, three pairs of electrons are shared between the two nitrogen atoms, and a triple covalent bond is...
3.3. Triple Covalent Bond The triple covalent bond is the strongest type of covalent bond, as it involves the sharing of three pairs of electrons between two atoms. Examples of molecules with triple covalent bonds include nitrogen (N2) and acetylene (C2H2). 4. Importance of Covalent Bonds 4.1...
