How Well Do You Know Ionic And Metallic Bonding?

1. When electrons are completely transferred, they will form ions and ionic compounds. This is known as _______ ________

Ionic bonding occurs when electrons are completely transferred between atoms, resulting in the formation of ions and ionic compounds. In this type of bonding, one atom loses electrons to become a positively charged ion (cation), while another atom gains those electrons to become a negatively charged ion (anion). The attraction between these oppositely charged ions creates a strong bond, known as ionic bonding. This type of bonding is typically observed between metals and nonmetals.

3. Explain why sodium chloride has a high melting point

Sodium bromide exist as giant ionic lattice. A lot of energy is required to overcome the stron _____ attraction between the positively charged Na⁺ and Cl^-ions. Hence sodium bromide has a high melting point.

Sodium chloride has a high melting point because it exists as a giant ionic lattice. The positively charged sodium ions (Na+) and negatively charged chloride ions (Cl-) are strongly attracted to each other due to electrostatic forces. These forces of attraction are very strong, requiring a lot of energy to overcome and separate the ions. Therefore, sodium chloride has a high melting point.

5. Which of the following is untrue for an ionic compound?

It has a giant 3 dimensional lattice in solid form

It dissolves well in water

It is soft and malleable

It conducts electricity in molten form

It has a high melting and boiling point

An ionic compound is made up of ions, which are held together by strong electrostatic forces of attraction. These forces create a rigid and ordered structure, resulting in a giant 3-dimensional lattice in solid form. This lattice structure makes ionic compounds hard and brittle, rather than soft and malleable. Therefore, the statement "It is soft and malleable" is untrue for an ionic compound.

6. Explain why aluminium is a good electrical conductor

Aluminum exist as giant metallic lattice. Each aluminium atom loses 3 valence electrons to form a latice of positively charge Al³⁺ ions surrounded by 'sea' of electrons. Presence of ________ ________ which can flow under applied potential makes aluminium a good electrical conductor.

Aluminum is a good electrical conductor because it has mobile electrons. In its metallic lattice structure, each aluminum atom loses three valence electrons, creating positively charged Al3+ ions. These ions are surrounded by a "sea" of delocalized electrons that are free to move throughout the lattice. When an electric potential is applied, these mobile electrons can easily flow, allowing for the efficient transfer of electric charge and making aluminum an excellent conductor of electricity.

7. Why are metals soft and malleable?

Because they are cute and adorable

Because they experience electrostatic repulsion

Because of the presence of mobile electrons

The metal cations can slip over each other fairly easily.

None of the above

Metals are soft and malleable because the metal cations can slip over each other fairly easily. This is due to the presence of mobile electrons in metals, which allow the cations to move and slide past each other. As a result, metals can be bent, shaped, and deformed without breaking. The presence of mobile electrons also contributes to other properties of metals, such as their high electrical and thermal conductivity.
