Bonding.

• A covalent bond forms when electrons are shared between atoms, allowing the atoms to fill their outer shells and achieve stability.
• Ionic compounds form when one atom loses an electron to another atom, resulting in positive and negative ions that attract each other through electrostatic forces.
• Ionic bonds occur when one atom loses an electron to another, resulting in the formation of positive and negative ions that attract each other.
• Single, double and triple covalent bonds determine the strength of attraction between atoms.
• Chemical bonds are formed by the transfer or sharing of electrons between atoms.
• A covalent bond occurs when electrons are shared between two non-metal atoms to form a molecule.
• Covalent bonds are typically strong and directional bonds that provide stability and rigidity to molecules and crystals.
• The bond between two atoms is called a chemical bond.
• Polarity refers to the degree of separation of positive and negative charges within a molecule.
• Covalent bonds can be polar or nonpolar depending on whether there is an unequal sharing of electrons.
• Nonpolar molecules have no permanent dipole moment due to equal sharing of electrons.
• Metallic bonds occur when metal atoms lose electrons to create positively charged ions, which then arrange themselves into a regular lattice structure held together by strong metallic bonds.
• Hydrogen bonds involve the sharing or transfer of hydrogen atoms between molecules, leading to weak attractions between them.
• The strength of chemical bonds can be measured using various methods such as melting point, boiling point, enthalpy change of formation, and spectroscopy.
• Metallic bonds involve the sharing of valence electrons among metal atoms, leading to strong metallic bonds with high melting points.
• Hydrogen bonds are weak intermolecular attractions formed by hydrogen atoms attached to highly electronegative elements such as oxygen or nitrogen.
• The strength of ionic bonds depends on factors like charge density, distance between ions, and size of the ions involved.
• The number of bonds formed by an element determines its position on the periodic table.
• Metals tend to lose electrons easily due to having low ionization energy.
• Non-metals tend to gain electrons easily due to having high electron affinity.
• The number of valence electrons determines whether an element will gain or lose electrons during chemical reactions.
• Metals tend to lose electrons while non-metals tend to gain them.
• Electrovalency is determined by the number of electrons gained/lost by an ion.
• The number of covalent bonds formed depends on the valence shell electron configuration of the elements involved.
• The number of electrons involved in a covalent bond is determined by the difference in atomic numbers (number of protons) between the two atoms.
• Ionic compounds have high melting points due to their strong electrostatic forces of attraction.
• In a single covalent bond, both atoms share one pair of electrons.
• Bonds can be ionic (electrostatic) or covalent (sharing).
• Electron pairs may share their space equally or unequally.
• In a double covalent bond, both atoms share two pairs of electrons.
• Metallic bonding is a type of chemical bonding where metal atoms lose their outermost electrons and become positively charged ions.
• Metallic bonding involves the delocalization of valence electrons among metal atoms, resulting in metallic properties such as conductivity and malleability.
• Ionic compounds consist of positively charged metal ions (cations) and negatively charged non-metal ions (anions).
• These ions arrange themselves into a regular lattice structure held together by electrostatic attractions.
