Compounds & elements
The periodic table is a table of the chemical elements in which the elements are arranged by order of atomic number in such a way that the periodic properties (chemical periodicity) of the elements are made clear. The standard form of the table includes periods (usually horizontal in the periodic table) and groups (usually vertical). Elements in groups have some similar properties to each other. There is no one single or best structure for the periodic table but by whatever consensus there is, the form used here is very useful. The periodic table is a masterpiece of organised chemical information. The evolution of chemistry's periodic table into the current form is an astonishing achievement with major contributions from many famous chemists and other eminent scientists. s and non-metalloids.

If the periodic table wasn't invented we be confused on how to categorize.
Up above there is silver(Ag), like many other elements they have names that represent them like gold(Au), iron(Fe), and boron(B). Some of the elements like boron have just 1 letter that represents them, and others have 2 letters, always remember if they have 2 letter the first has to be caped and the other one lower cased.
Now here is a compound salt, if you don't know what a compound is, it's a compound is two elements combined to make a greater matter. There is two types of bonds common in compounds are covalent and ionic bonds. The salt compound is made by two elements. This doesn't mean that every compound is made by two element, like water it's made by two hydrogen and one oxygen.
