Aluminum has the symbol Al. Its atomic number is 13. It’s electron configuration is 1s2 2s2 2p6 3s2 3p1. It is a lightweight silvery-white metal belonging to the 13th group of the periodic table. It is used in a variety of products, including power lines, consumer electronics, ships, spacecraft components, foils, cans, kitchen utensils, beer kegs, and airplane parts. The main advantage of aluminum is It is an excellent heat and electricity conductor and, in relation to its weight, is almost twice as good a conductor as copper. Sulfur, with the symbol S, its atomic number is 16, and its electron configuration is 1s2 2s2 2p6 3s2 3p4. It is a non-metallic chemical element. It belongs to the oxygen group. It is odorless, tasteless, and light yellow solid. Sulfur is essential to all living things. It is used in batteries, fungicides, detergents, fertilizers, gunpowder, fireworks, and matches. Antoine Lavoisier discovered it in the year of 1777.

Aluminum Sulfide Formula

Aluminum Sulfide is a chemical compound with the formula Al2S3. It is also called dialuminium trisulfide. It is an ionic compound of aluminum and sulfur. It is a grey chemical compound. Aluminum Sulfide is an inorganic compound used extensively as a raw material in the production of hydrogen sulfide gas.

Structure Of Aluminum Sulfide

 

Preparation of Aluminium Sulfide

Aluminum is a metal, and sulfur is a nonmetal, so when they combine, an ionic compound is formed by transferring electrons from the metal to non-metal

Sample Questions

Question 1: Why Aluminium Sulfide is ionic?

Answer:

Aluminum is a metal, and sulfur is a nonmetal so when they combine, an ionic compound is formed by transferring electrons from the metal to the non-metal. Therefore, the bond is ionic.

Question 2: What are the uses of Aluminium?

Answer:

Aluminum is used in a variety of products, including packing, cans, window frames, computers, cellphones, foils, and airplane parts. Aluminum is also a great conductor of electricity, and it is much cheaper than its counterpart, Copper. So it is used in electric wires and other such power transmission lines.

Question 3: Is Aluminium react with Nitrogen?

Answer:

Aluminum reacts with nitrogen to produce aluminum nitride. Aluminum has a higher affinity for oxygen than nitrogen, and so in the presence of oxygen and nitrogen will form Al2O3 in reference to aluminum nitride.

Question 4: Aluminium Sulfide is acid or base?

Answer:

Aluminum Sulfide is acidic. When Aluminium Sulfate reacts with water, it produces Aluminium hydroxide and a diluted sulfuric acid solution which changes the soil’s acidity.

Question 5: What are the food sources of aluminum?

Answer:

The most commonly used foods that contain essential amounts of aluminum-containing food additives are backing powders, cake mixes, processed cheeses, and pickled vegetables.

Question 6: What Aluminium does do to your body?

Answer:

Little exposure to aluminum is normally not harmful, but exposure to very high levels can affect the health. It attacks your central nervous system and is linked to degenerative brain diseases. Breathing aluminum dust in large amounts can have lung diseases.

Question 7: What is the special about Sulfur?

Answer:

Sulfur has many uses. It is used to make car batteries, refine oil, and fertilizer, and extract minerals. Pure sulfur is a tasteless, odorless, brittle solid that is pale yellow in color, and it is a poor conductor of electricity and insoluble in water. Sulfur reacts with all metals except gold and platinum, forming sulfides.
