On the first two columns of the table, i.e., Magnesium, Potassium, Sodium, Calcium,..
Lithium is in the first period of the periodic table. It is the first element in the alkali metal group.
Potassium (K) is the alkali metal located in the fourth period of the periodic table.
yes, it is an element. You can check it in the periodic table.
Ir refers to iridium element that is placed in group-9 and period-6 in the modern periodic table.
the period fathest to the left is the alkali earth metals. which from top to bottom would be: hydrogen lithium sodium potassium rubidium cesium and francium
