# Atomic Number of Metal ‚A‛ is 11, While Atomic Number of Metal ‚B‛ is 20. Which of Them Will Be More Reactive? Write the Chemical Reaction of Dilute Hcl with Metal ‚A‛. - Science and Technology 1

Atomic number of metal ‚A‛ is 11, while atomic number of metal ‚B‛ is 20. Which of them will be more reactive? Write the chemical reaction of dilute HCl  with metal ‚A‛.

#### Solution

Metal ‘A’ is more reactive than metal ‘B’.
Atomic number of metal ‘A’ is 11, hence it is Na.

2Na + 2HCI  → 2NaCI(aq)  + H_2 (g)
