alkaline earth metals
In the old numbering system, "A" simply refered to the the left side of the table. Group IA,IA are alkali metals.
in periodic table،there are many groups of elements. group 1 is called alkaly metals . Group 2 is called alkaline earth metal.
The names for elements 104-108, seaborgium (Sg), bohrium (Bh), hassium (Hs), meitnerium (Mt) and darmstadtium (Ds), were proposed by the discoverers of these elements and were approved by the International Union of Pure and Applied Chemistry (IUPAC). The names were chosen to honor renowned scientists or places associated with the study of nuclear science.

Group 11 does not have its own names. The elements in this group are, Cu,Ag and Au. Their names are copper, silver and gold respectively.
Group 7 elements are halogens. They have seven valance electrons& are highly reactive. They are: -Fluorine -Chlorine -Bromine -Iodine
Elements of Group 18 may be called as;1-Noble gases 2-Rare gases 3- Inert gases
You can use memory aids such as mnemonics, acronyms, or visualization techniques to help remember the elements' names as you go down a group on the periodic table. Grouping elements with similar characteristics together can also make it easier to remember their names and properties. Practice and repetition are essential for reinforcing your memory of the elements' names in a particular group.

Some elements are named after the compound that they came from, or some attribute of it. Other elements are named after some aspect of the way in which the element was found. Still, there are other elements that get their names from places. Another interesting group of names comes from mythology. -Nev Singhota
