which metal react with steam but not with cold high melting point

why does sodium metal react so vigorously with water

The melting point also makes a difference to the reactivity with water. Lithium metal melts at 180 o C, so lithium in contact with water cannot get hot enough to melt. This limits its reactivity to surface interaction between liquid water and solid lithium, so lithium is the slowest to react. Sodium and all the other alkali metals have melting
