Matter and its Construction: Elements consist of Similar Atoms

The video tutorial explains that elements are substances with similar atoms. Chemists use symbols to represent elements, making it easier to express them. Symbols can be a single capital letter or a combination of a capital and a small letter. When elements have similar letters, a second letter is used to differentiate them. Some symbols are derived from Latin names, such as potassium, which is represented by 'K' from its Latin name 'calium'.
