- 1.
What are atoms trying to achieve when they bond with other atoms?
- A.
To lose all their electrons
- B.
To gain more electrons
- C.
To gain the same number of protons as noble gases
- D.
To obtain the same electronic configuration as noble gases
- E.
To become an alloy
Correct Answer
D. To obtain the same electronic configuration as noble gasesExplanation
Atoms combine to achieve greater stability through obtaining a noble gas structure either by transfering or sharing of electrons. Noble gases have the stable electronic structure.Rate this question:

Why are metals soft and malleable?
- A.
Because they are cute and adorable
- B.
Because they experience electrostatic repulsion
- C.
Because of the presence of mobile electrons
- D.
The metal cations can slip over each other fairly easily.
- E.
None of the above
Correct Answer
D. The metal cations can slip over each other fairly easily.Explanation
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.Rate this question:

Explain why sodium chloride has a high melting pointSodium 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.
Correct Answer
electrostaticExplanation
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.Rate this question:

Explain why aluminium is a good electrical conductorAluminum 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.
Correct Answer
mobile electronsExplanation
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.Rate this question:

When electrons are completely transferred, they will form ions and ionic compounds. This is known as _______ ________
Correct Answer
ionic bondingExplanation
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.Rate this question:

The overall process of achieving stability is _________
Correct Answer
Explanation
The overall process of achieving stability is a continuous and dynamic one. It involves maintaining a state of balance and equilibrium in various aspects such as physical, mental, emotional, and financial well-being. This process requires identifying and addressing any imbalances or disruptions that may arise, implementing strategies to manage stress and challenges, and fostering resilience and adaptability. It also involves nurturing supportive relationships, seeking personal growth and self-care, and making choices that align with one's values and goals. Ultimately, achieving stability is an ongoing journey that requires self-awareness, effort, and a willingness to adapt to change.Rate this question:

How would you make Potassium Chloride a good conductor of electricity?
- A.
Grind it into a fine powder
- B.
Freeze it
- C.
Heat it above its melting point
- D.
Mix it with solid sodium chloride
- E.
None of the above.
Correct Answer
C. Heat it above its melting pointExplanation
By heating it above its melting point, it becomes a liquid or moleten which would then have mobile ions to conduct electricityRate this question:

Which of the following is untrue for an ionic compound?
- A.
It has a giant 3 dimensional lattice in solid form
- B.
It dissolves well in water
- C.
It is soft and malleable
- D.
It conducts electricity in molten form
- E.
It has a high melting and boiling point
Correct Answer
C. It is soft and malleableExplanation
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.Rate this question:

Explain why aluminium is a good heat conductorAluminium exists as a giant metallic lattice. Metals are good heat conductor as the atoms are closely packed. Heat energy can be easily transferred from one atom to another by _____ as well as collisions of mobile electrons
Correct Answer
vibrationsExplanation
Aluminium is a good heat conductor because it exists as a giant metallic lattice, where the atoms are closely packed. In metals, heat energy can be easily transferred from one atom to another through vibrations. Additionally, the mobile electrons in metals also contribute to the conduction of heat through collisions.Rate this question:

Ionic bonds are usually formed between ______ and ______.
Correct Answer
metals and non-metals
metals;non-metals
metals, non-metals
metals non-metalsExplanation
Ionic bonds are usually formed between metals and non-metals. This is because metals tend to lose electrons and become positively charged ions, while non-metals tend to gain electrons and become negatively charged ions. The attraction between these oppositely charged ions results in the formation of ionic bonds.Rate this question:
