Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Chemical Symbols

Chemical symbols are one- or two-letter notations used to represent chemical elements. The first letter is always capitalized, while the second, if present, is lowercase. For example, 'H' represents hydrogen, and 'O' represents oxygen. Understanding these symbols is essential for identifying elements in chemical formulas and equations.

Periodic Table of Elements

The periodic table organizes all known chemical elements based on their atomic number, electron configuration, and recurring chemical properties. Elements are grouped into rows (periods) and columns (groups) that reflect their similarities. Familiarity with the periodic table helps in recognizing elements by their symbols and understanding their relationships.

Element Names

Each chemical element has a unique name that corresponds to its chemical symbol. These names often derive from Latin, Greek, or the names of scientists. For instance, 'Sb' stands for antimony, 'Pb' for lead, and 'Hg' for mercury. Knowing the names of elements is crucial for effective communication in chemistry and for understanding their applications.

Textbook Question

A solid white substance A is heated strongly in the absence of air. It decomposes to form a new white substance B and a gas C. The gas has exactly the same properties as the product obtained when carbon is burned in an excess of oxygen. Based on these observations, can we determine whether solids A and B and gas C are elements or compounds?
