- 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
- 2.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
- 3.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.
- 4.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.
- 5.When electrons are completely transferred, they will form ions and ionic compounds. This is known as _______ ________
- 6.The overall process of achieving stability is _________
- 7.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.
- 8.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
- 9.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
- 10.Ionic bonds are usually formed between ______ and ______.
