Inv 3 Exp 1 - Ionic Bonds - Day 2

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 between a metal and a non-metal.

Front

What is the total charge of an ionic compound?

Back

Neutral.

Front

What is the melting point trend of ionic compounds?

Back

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

Front

How do ionic compounds conduct electricity?

Back

Ionic compounds do not conduct electricity in solid form because the ions are fixed in place. They conduct electricity when melted or dissolved in water, as the ions are free to move.

Front

What is the most probable ion formed by an atom with 3 electrons in its outer shell?

Back

X³⁺.

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 is the difference between cations and anions?

Back

Cations are positively charged ions formed by the loss of electrons, while anions are negatively charged ions formed by the gain of electrons.

Front

What factors affect the melting points of ionic compounds?

Back

The melting points of ionic compounds are affected by the charge of the ions and the size of the ions; higher charges and smaller sizes generally lead to higher melting points.

Front

What is the role of lattice energy in ionic compounds?

Back

Lattice energy is the energy released when ions bond to form an ionic solid; it is a measure of the strength of the ionic bonds.

Front

How does the size of ions affect ionic bond strength?

Back

Smaller ions can pack closer together, leading to stronger ionic bonds due to increased electrostatic attraction.
