The elements of period 3 has same number of shells as sodium. These elements are Mg, Al , Si, P , S, Cl and Ar.
The chemists' shorthand for elements is called chemical symbols. For example, instead of writing out 'selenium,' it can be quickly written as 'Se.'
Chemical symbols are important because they provide a standardized method for representing elements and compounds in a concise manner. They allow scientists to communicate about specific chemical species regardless of language barriers. Additionally, chemical symbols are used in equations to show the composition and reactions of substances.
In the periodic table, elements' names are written with a capital letter for the first letter only, like Oxygen (O) or Gold (Au). When chemical symbols are used, those symbols are capitalized.
Not always... There are chemical elements beginning with the same letter - for example Copper and Cobalt. However - every chemical symbol does consist of two letters.
The chemical sign for carbon dioxide is CO2
Chemical elements and compounds are written with lower case letters. Only for chemical symbols do you use capitals, such as Cu for copper, etc.
Chemical symbols for compounds are written by combining the chemical symbols of the elements in the compound, along with subscripts to indicate the number of atoms of each element present. For example, water (H2O) is composed of two hydrogen atoms and one oxygen atom. The chemical symbols are always listed with the element that appears first in the compound listed first.

Atomic symbols are used to represent elements, a negative (-) and a psoitive (+) represent electrons and protons, respectively. Chemicals or other compounds are often written as a combination of atomic symbols with subscripts to indicate the presence of multiple atoms.

The peridodic table is a listing of all the known elements. These elements are then broken down into groups and families, gases, liquids, solids, metals, nobal gases etc. etc. displying each elements atomic number which also tells you about the element. The chemical symbol of each element is included also and is what the element is commonly written as. Chemical symbols: - they are used in formulas and word equations (chemical equations) e.g. water's chemical symbol is H2O (2H - HYDROGEN ATOMS, 1 O- OXYGEN ATOM) etc. - the chemical symbols of compounds and other substances including acids and bases etc. are made up of the element in the compound. The periodic table helps you understand more about the elements and is extremely helpful in learning the chemical language.
