Sodium
Lithium is the element that produces a red flame when it reacts with water.
water
The metal that reacts slowly with cold water to form a hydroxide is magnesium. When magnesium reacts with water, it forms magnesium hydroxide and hydrogen gas.
Potassium (K) reacts most rapidly with water.
Some metals in the table do not react with water
Sodium reacts violently with water, while sodium chloride (or table salt) dissolves in water.
Sodium reacts with water to produce Sodium hydroxide and Hydrogen gas.2Na + 2H2O = 2NaOH + H2
Magnesium is the element that loses 2 atoms when reacting, reacts slowly with water, and can conduct electricity.
For example, water reacts with zinc, releasing hydrogen, an element.
Any of the alkali metals (in group one of the periodic table)
fluorine reacts with water veryviciously the chemical equation for it is fluorine + oxygen = fluorine oxide
