The s-block elements are located in the leftmost two columns of the periodic table, comprising the elements from group 1 (alkali metals) and group 2 (alkaline earth metals). Na is a group 1 element and therefore belongs to the s-block. The other choices, Cm (Curium) and Ta (Tantalum), are d-block elements, and F (Fluorine) is a p-block element.
