Chapter 6 The Structure of Matter

Front

What is the melting point of quartz and why?

Back

Quartz has a high melting point due to the strong bonds between its atoms.

Front

Why do atoms form bonds?

Back

Atoms form bonds to become more stable.

Front

How does the attraction between molecules compare to the attraction between ions?

Back

The attraction between molecules tends to be weaker than the attraction between ions.

Front

What does the name 'dinitrogen tetroxide' indicate about its composition?

Back

It contains 2 nitrogen (N) atoms and 4 oxygen (O) atoms.

Front

What charge do anions have?

Back

Anions have a negative charge.

Front

Define ionic bond.

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

What is the difference between an anion and a cation?

Back

An anion is a negatively charged ion, while a cation is a positively charged ion.

Front

What is the significance of the octet rule in bonding?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving stability.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together, representing the smallest fundamental unit of a chemical compound.
