Most atomic symbols are based on the latin name of the element. Latin was a common language of science for hundreds of years, and the symbols remained, though each language has their own name for the elements.
Some of the symbols come from their name in Latin or ancient Greek. For example, gold (Au) is Aurum in Latin and potassium (K) is Kalio (κάλιο) in Greek. Others, like carbon (C), are from English.
They do relate to the name of the element ... just not the English name of the element.
For example, the symbol for silver is Ag, from its Latin name (argentum) and that of gold is Au again from the Latin name (aurum). In nearly all cases where the symbol doesn't obviously come from the English name it comes from the Latin name, with the one exception of tungsten, which has a symbol of W from its name in most Slavic and Germanic languages other than English, wolfram.
because the word comes from the Latin or Greek word that starts with the same letter
It is based on number of protons. Consider an element has 20 protons.Its atomic number is twenty.
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.
Some were were given symbols from their names in other languages.
Iodine is a halogen. Single atom has 53 protons.
Atomic Number Number of Protons and Electrons (Atomic Number) Atomic Mass General electronegativity, radius, and ionization energy based on the position of an element on the Periodic Table.
carbon
the number of protons in the nucleus of an element.
the number of protons in the nucleus of an element.
It is based on number of protons. Consider an element has 20 protons.Its atomic number is twenty.
Atomic number is the number designated to an element based on the ammount of protons an element has in its nucleus.
The atomic number of an element is based on the number of protons in its nucleus because it is equivalent to its charge number.
