The reaction makes it hot enough to melt into a silvery ball. That's also why people can't survive on sea water.

The alkali metals comprise Group 1 of the periodic table, and include lithium, sodium, potassium, rubidium, cesium and francium. (See accompanying sidebar.) This page looks at the reactions of the Group 1 elements - lithium, sodium, potassium, rubidium and caesium - with water.
That's the flash and bang for you. It reacts faster with hot water!

Our kidney can remove excess salt, but only by flushing it out with water.

Elements are grouped according to their properties.

Remember when your high school teacher dropped a lump of sodium into water?

Since water can turn into hydroxide and hydrogen ion the sodium ion is able to displace the hydrogen ion.

It makes up the difference by using water … The alkaline earth metals comprise Group 2, and include beryllium, magnesium, calcium, strontium, barium and radium.

Group 13 elements are not very reactive with water. Aluminum does not appear to react with water because an outer layer of aluminum oxide (Al 2 … I watched an irregular piece of sodium (~20 grams) bubble in water (initially cold) until it melted and became globular - just before it exploded! Reactions involving sodium hydroxide do not stop here.

Bang! Why sodium explodes in water ... Chemistry teachers love to use the sodium-water reaction when they are teaching students about the periodic table. During the reaction, the sodium metal may well become so hot that it catches fire and burns with a characteristic orange colour. Most alkali metals and alkaline earth metals react with water to produce hydrogen. Sodium also reacts with most other elements and with many compounds.

The resulting solution is basic because of the dissolved hydroxide. Sodium has one valence electron that is shielded (in proportion to the nuclear charge) but it is quite stable in isolation. How does sodium chloride (NaCl) dissolve in water?

The outer electron is not strongly attached and can be stolen away by many other atoms. Sodium is less dense than water and will float on water’s surface as it reacts.

Lighter than water, sodium can be cut with a knife at room temperature but is brittle at low temperatures. When potassium reacts with water it catches fire, generating a purple glow.


Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and hydrogen gas (H 2).

Lithium is reminiscent of magnesium in water, where magnesium develops a protective oxide/hydroxide coat which inhibits further reaction with water unless the water is very hot. Sodium chloride (NaCl) dissolves when water molecules continuously attack the NaCl crystal, pulling away the individual sodium (Na +) and chloride (Cl –) ions.This nonstop attack continuous until the whole NaCl crystal disintegrates. The reaction is exothermic. For decades, science enthusiasts have delighted at the famously energetic way sodium and potassium explode on contact with water. What Else Does Sodium Hydroxide React With? It conducts heat and electricity easily and exhibits the photoelectric effect (emission of electrons when exposed to light) to a marked degree.

This makes it more reactive to say elements like fluorine or oxygen.

It is also utilised in water treatment, construction technology and the paper industries.

Sodium reacts violently with water because it is much more active than hydrogen. In fact, lithium and calcium, given the same conditions, react more slowly with water than does sodium.
