Elements are arranged in order of increasing atomic number
An element is a substance that is made up of one type of atom. The atoms of an element are all the same. The order of the elements is based on the increasing number of protons in the nucleus of the atom.
Symbol of an Element
The symbol of an element is a unique letter, number, or combination of letters and numbers that represents a specific element. The symbol is used to identify the element in chemical formulas and in the periodic table of the elements. For example, the symbol for hydrogen is H, the symbol for carbon is C, and the symbol for oxygen is O.
Symbols and How They are Derived?
There are a variety of ways to derive symbols. One way is to take an existing symbol and modify it. For example, the dollar sign ($) is derived from the letter S, which is the first letter of the word “dollar.” Another way to derive symbols is to create new symbols altogether. For example, the mathematical symbol for infinity (∞) is derived from the letter M, which is the first letter of the word “infinity.”
