Ionic, Covalent, Metallic Bonds, Network Solids

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically formed when one atom donates an electron to another.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons, allowing each atom to attain the electron configuration of a noble gas.

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move, allowing metals to conduct electricity and heat.

Front

What are network solids?

Back

Network solids are a type of solid where atoms are bonded by covalent bonds in a continuous network, resulting in high melting points and hardness, e.g., diamond.

Front

Which type of bond is typically formed between metals and nonmetals?

Back

Ionic bonds are typically formed between metals and nonmetals.

Front

What is the characteristic of molecular solids?

Back

Molecular solids are composed of molecules held together by intermolecular forces, resulting in lower melting points compared to ionic or covalent network solids.

Front

What is the significance of electronegativity in bond formation?

Back

Electronegativity is a measure of an atom's ability to attract electrons; it plays a crucial role in determining the type of bond (ionic, covalent) that will form between atoms.

Front

What is the melting point trend in ionic compounds?

Back

Ionic compounds generally have high melting points due to the strong electrostatic forces between the ions.

Front

How do metallic bonds contribute to electrical conductivity?

Back

Metallic bonds allow electrons to move freely throughout the metal, enabling it to conduct electricity in both solid and liquid states.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds occur when electrons are shared unequally between atoms, while nonpolar covalent bonds occur when electrons are shared equally.
