There are 18 groups (columns) in the periodic table. Group 1 (also known as the alkali metals) is the column on the far left of the table. Elements in the same group have similar, but not identical characteristics. This is because they all have the same number of electrons in their outermost shell.
Group 1 of the periodic table is known as the 'Alkali Metals' because they are metals that form alkaline compounds when they react with water. The alkali metals are the metals in Group 1 (the first column of the periodic table). Hydrogen is also in Group 1, and so is technically considered to be part of the alk â¦ ali metal group/family. Hydrogen is in fact a non-metal, however, and does not generally exhibit behavior similar to the other Group 1 elements.
