I guess the question is: Why do SOME element symbols etc. This has to do with the language in which the element has been named. lead for example has Pb as the symbol. Pb stands for plumbum which in Latin means lead.... you still recognise the same roots in the profession's name 'plumber'
The same applies for many other seemingly unrelated symbols.

Some examples
The name sodium probably originates from the Arabic word suda meaning 'headache' as the headache-alleviating properties of sodium carbonate or soda were well known in early times.
The term "potash" comes from the old-Dutch word potaschenan old method of making potassium carbonate (K2CO3) was by leaching wood ashes and evaporating the solution in large iron pots, leaving a white residue called "pot ash", which in turn gave the element its modern name.
Mercury is named after the Roman god Mercurius and the planet Mercury, both known for speed and mobility.
Mercury is the only metal for which the alchemicalplanetary name became the common name in Anglo-languages. In German(-like) languages 'quicksilver' is used as root name.
The Latin name of the element was the model.
The codes on the periodic table that represent an element are called element symbols. These symbols are typically one or two letters that represent the element's name, often derived from the element's English or Latin name.
Chemical symbols use one or two letters from the name of the element.
The symbols for elements are typically derived from their Latin or Greek names. Sometimes the symbols are based on old names or properties of the element, which may not directly relate to their modern English names. Over time, these symbols have become standardized and widely accepted in the field of chemistry.
Because it's easier than having to write them all out every time. Also, they get their symbols from their Greek names.

Well it's because sometimes the element has an old name which it uses as an element symbol
It's easier to navigate the periodic table and write chemical equations and formulae once you know the symbols for the elements. However, sometimes it's easy to confuse symbols of elements with similar names. Other elements have symbols that don't seem to relate to their names at all! For these elements, the symbol usually refers to an older element name that isn't used any more. Here's an alphabetical list of element symbols with the corresponding element name. Keep in mind that the names for the elements (and their symbols) may be different in languages other than English.
Most elements have either 1 or 2 letters but some elements such as Ununpentium, have 3 (Uup)
We have chemical symbols so that we can quickly write about an element or compound with out having to write out the name every time you want to refer to it.
The chemical symbols are approved by IUPAC; symbols are derived from the name of the chemical element in Latin, frequently the first two letters.
No. Some symbols are based on the element's name in some other language (usually, but not always, Latin). For example tungsten's symbol is W, from its German name Wolfram, while iron's symbol is Fe, from its Latin name ferrum.
The symbols for elements are based on their Latin or Greek names. Sometimes the symbols may not directly correspond to the full name of the element due to historical or linguistic reasons. For example, the symbol for sodium (Na) comes from its Latin name "natrium."
