Could You Really Recognize Sulphur?

Explanation
Sulphur has an atomic mass of 32. This is because the atomic mass of an element is determined by the sum of the number of protons and neutrons in its nucleus. Sulphur has 16 protons and an average of 16 neutrons, giving it an atomic mass of 32.

Explanation
The correct answer is 115.2 °C because it is the closest option to the actual melting point of sulfur, which is around 115.2 °C.

Explanation
The atomic number of an element represents the number of protons in the nucleus of an atom of that element. In the case of sulphur, the atomic number is 16, indicating that a sulphur atom has 16 protons. The atomic number is a unique identifier for each element and is used to organize the elements in the periodic table.

Explanation
The correct answer is S. Sulphur is a chemical element with the symbol S on the periodic table. The symbol represents the Latin name for sulphur, "sulfurum."

Explanation
Sulphur molecule has 8 atoms. This is because the chemical formula for sulphur is S8, indicating that there are 8 atoms of sulphur in a molecule.

Explanation
Sulphur is used in the production of fireworks. It is commonly used to create the bright colors and effects in fireworks. When sulphur is burned, it produces sulfur dioxide gas, which reacts with other chemicals to create different colors. The addition of sulphur helps to control the combustion process and create the desired visual effects in fireworks. Therefore, fireworks are the correct answer as sulphur is an essential component in their production.

Explanation
Hydrogen sulphide is the compound of sulphur that has an odour akin to rotten eggs. This is because hydrogen sulphide is a gas that is produced by the decomposition of organic matter containing sulphur. It has a distinct smell that is often described as being similar to the smell of rotten eggs.

Explanation
Sulphur is found in period 3 on the periodic table. Periods in the periodic table represent the number of energy levels or shells that an element's electrons occupy. As sulphur has 16 electrons, it occupies the third energy level, which corresponds to period 3.

Explanation
Sulphur has a melting point of 388.36 K. This means that at temperatures below 388.36 K, sulphur exists in a solid state, and at temperatures above 388.36 K, it melts and becomes a liquid.

Explanation
Antoine Lavoisier is recognized as the person who discovered and recognized sulphur as an element. Lavoisier was a French chemist who conducted extensive experiments and observations on chemical reactions. He played a crucial role in the development of the modern understanding of chemical elements and their properties. Through his experiments, Lavoisier was able to identify and classify sulphur as a distinct element, contributing significantly to the field of chemistry.
