Sodium (Na; from Latin for Nadium)
Sodium metal reacts with oxygen in the air to form the oxide
4Na + O2 = 2Na2O
Sodium reacts with water to form the hydroxide,(lye) with the liberation of hydrogen .
2Na + 2H2O = 2NaOH + H2
Sodium reacts with chlorine to form sodium chloride (Table Salt)
2Na + Cl2 = 2NaCl (Table salt).
Highly reactive elements easily react with other substances in the environment, forming compounds rather than existing in their pure form. This is why it is rare to find pure samples of highly reactive elements in the ground.
Hydrogen
Chlorine is a highly reactive element. It readily reacts with other elements to form compounds, such as sodium chloride (table salt) or hydrochloric acid.
Silver is not highly reactive and is considered a noble metal. It does not easily react with most chemicals but can react with sulfur compounds in the air, leading to tarnishing or discoloration of the metal.
Chlorine is a highly reactive chemical element, known for its strong oxidizing properties. It readily forms compounds with other elements, such as sodium chloride (table salt) or hydrochloric acid.
Chlorine and fluorine, with fluorine more reactive. Some would also include oxygen. (The two remaining halogens are not gaseous at room temperature.)

sodium!
Chlorine is more reactive than silicon. Chlorine readily reacts with a variety of elements and compounds to form chlorides, while silicon is less reactive and forms fewer compounds with other elements.
Hydrogen
Chlorine is a highly reactive element. It readily reacts with other elements to form compounds, such as sodium chloride (table salt) or hydrochloric acid.
Fluorine forms a very large range of compounds since it is highly reactive (actually it is the most reactive element there is). Teflon and freon are both synthetic fluorine compounds. Fluorine salts such as potassium fluoride are used in toothpaste, or to fluoridate water.
Sodium
Silver is not highly reactive and is considered a noble metal. It does not easily react with most chemicals but can react with sulfur compounds in the air, leading to tarnishing or discoloration of the metal.
Fluorine, F, is the most reactive element of all.
bromine!
Chlorine is a highly reactive chemical element, known for its strong oxidizing properties. It readily forms compounds with other elements, such as sodium chloride (table salt) or hydrochloric acid.
