Unit 3 Ionic Bonding Metallic Bonding

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 transfers electrons to another.

Front

What happens to electrons in ionic bonding?

Back

In ionic bonding, electrons are transferred from one atom (usually a metal) to another atom (usually a non-metal), resulting in the formation of cations and 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

What is the role of opposite charges in ionic bonding?

Back

Opposite charges attract each other, which is the fundamental principle that holds cations and anions together in an ionic bond.

Front

What is the Lewis dot structure?

Back

The Lewis dot structure is a diagram that represents the valence electrons of an atom and shows how they are involved in bonding.

Front

How do you determine the number of atoms in a chemical formula?

Back

The number of atoms in a chemical formula is indicated by the subscripts following each element symbol. For example, in Al2O3, there are 2 aluminum atoms and 3 oxygen atoms.

Front

What is the significance of electron transfer in ionic bonding?

Back

Electron transfer is crucial in ionic bonding as it leads to the formation of charged ions, which then attract each other to form a stable ionic compound.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the attraction between charged ions, while covalent bonds involve the sharing of electrons between atoms.

Front

What is the octet rule?

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 greater stability.
