FLASHCARD QUESTION

Front

What is ionic bonding?

Back

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

2.

FLASHCARD QUESTION

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.

3.

FLASHCARD QUESTION

Front

Which compound has a higher melting point: MgO or NaCl?

Back

MgO has a higher melting point due to stronger ionic bonds compared to NaCl.

4.

FLASHCARD QUESTION

Front

Why does magnesium have a higher melting point than sodium?

Back

Magnesium has a higher melting point because it contributes two additional electrons per atom to the electron sea compared to sodium's one.

5.

FLASHCARD QUESTION

Front

What determines the strength of an ionic bond?

Back

The strength of an ionic bond is determined by the charges of the ions and the distance between them; higher charges and shorter distances result in stronger bonds.

6.

FLASHCARD QUESTION

Front

What is the significance of the ionic charge in BeO compared to NaCl?

Back

BeO has a larger ionic charge than NaCl, which contributes to its stronger ionic bond.

7.

FLASHCARD QUESTION

Front

What is the most suitable metal for making a crucible to melt sodium?

Back

Calcium (Ca) is suitable because it has a higher melting point than sodium.
