The elements in group 17 are known by the name halogens. They are non-metal elements and are at times referred to as salts.
An atomic symbol is a 1-, 2-, or 3-letter code that represents an element. If the symbol consists of one letter, like carbon (C), the letter is capitalized. If the symbol consists of two letters, like magnesium (Mg), the first letter is capitalized, but the second letter is not. The 3-letter codes are for elements that have been recently synthesized and have not been given a permanent name, and for elements that have yet to be synthesized, both of which are given temporary systematic names based on their atomic numbers. An example is element 115, with the symbol Uup, which is currently named ununpentium, which means one, one, five. Eventually this element will be given a permanent name with either a 1-letter or 2-letter symbol.

Halogens
In the field of chemistry, elements with atomic numbers higher than 104 are known as transuranium elements and most of them do not have permanent names yet. These elements are typically synthesized in laboratories and are highly unstable, making it challenging to study and name them definitively. Instead, they are often assigned temporary systematic names based on their atomic numbers until further research can confirm their properties and characteristics.
