Ionic and Metallic Bonding

Front

What is ionic bonding?

Back

Ionic bonding is the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions) formed through the transfer of electrons from one atom to another.

Front

What is metallic bonding?

Back

Metallic bonding is the force of attraction between free-floating valence electrons and the positively charged metal ions, allowing metals to conduct electricity and heat.

Front

What is the significance of the octet rule in ionic bonding?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, leading to the formation of stable ionic compounds.

Front

What type of elements typically form ionic bonds?

Back

Ionic bonds typically form between metals, which lose electrons to become cations, and nonmetals, which gain electrons to become anions.

Front

What is a cation?

Back

A cation is a positively charged ion that is formed when an atom loses one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion that is formed when an atom gains one or more electrons.

Front

How does the melting point of ionic compounds compare to that of covalent compounds?

Back

Ionic compounds generally have higher melting points than covalent compounds due to the strong electrostatic forces between the ions.

Front

What is the role of delocalized electrons in metallic bonding?

Back

Delocalized electrons in metallic bonding allow for the conductivity of electricity and heat, as they can move freely throughout the metal lattice.

Front

Why are ionic compounds typically soluble in water?

Back

Ionic compounds are typically soluble in water because the polar water molecules can surround and separate the individual ions, overcoming the ionic bonds.

Front

What is the difference between a simple ionic compound and a complex ionic compound?

Back

A simple ionic compound consists of two elements (one metal and one nonmetal), while a complex ionic compound contains more than two elements, often including polyatomic ions.
