Question

show the formation of aluminum oxide by electron transfer method​

Answer 1

Answer:

The formation of aluminum oxide (Al2O3) by electron transfer method involves the transfer of electrons from the aluminum atoms to the oxygen atoms to form a stable ionic compound.

The electron configuration of aluminum is 1s2 2s2 2p6 3s2 3p1, while the electron configuration of oxygen is 1s2 2s2 2p4. Aluminum has three valence electrons, while oxygen has six valence electrons.

During the formation of aluminum oxide, each aluminum atom loses three valence electrons to form a positively charged ion (Al3+), while each oxygen atom gains two electrons to form a negatively charged ion (O2-). The resulting compound is composed of positively charged aluminum ions and negatively charged oxygen ions, which are held together by strong electrostatic forces of attraction.

The reaction can be represented as:

2Al + 3O2 → 2Al3+ + 3O2-

The Al3+ and O2- ions combine to form the ionic compound Al2O3, which has the chemical formula Al2O3.

Al3+ + O2- → Al2O3

The formation of aluminum oxide by electron transfer method results in a stable compound with a high melting point, which is commonly used in the production of ceramics, refractory materials, and abrasives.

Answer 2

Answer: By transferring electrons between aluminium and oxygen atoms, aluminium oxide, sometimes referred to as alumina, may be created. Below is the response:

• 2Al + 3/2 O2 produces Al2O3.

• In this reaction, three oxygen atoms get two electrons each to produce negatively charged oxide ions, while two aluminium atoms lose three electrons each to generate two positively charged aluminium ions (Al3+) (O2-). The resulting solid aluminium oxide is created by the subsequent 2:3 combination of the aluminium and oxide ions (Al2O3).

• The process of exchanging electrons between aluminium and oxygen atoms to create a compound with strongly electrostatically attracted oppositely charged ions is known as an ionic bond. Due to its high stability and hardness, aluminium oxide may be used in a wide range of manufacturing and industrial processes.
