Marking Scheme

  • 1Identifying the elements of the second period (0.5 marks)
  • 2Correctly identifying Lithium and Beryllium as the only metals (0.5 marks)

Hint

List the elements of the second period (atomic numbers 3 to 10) and identify which ones are classified as metals.

Quick Oral Answer

There are 2 metals in the second period of the periodic table: Lithium and Beryllium.

Analysis & Explanation

The second period of the periodic table consists of eight elements: Lithium (Li\text{Li}), Beryllium (Be\text{Be}), Boron (B\text{B}), Carbon (C\text{C}), Nitrogen (N\text{N}), Oxygen (O\text{O}), Fluorine (F\text{F}), and Neon (Ne\text{Ne}).


  • Lithium (Li\text{Li}) and Beryllium (Be\text{Be}) are metals (alkali metal and alkaline earth metal respectively).
  • Boron (B\text{B}) is a metalloid.
  • Carbon (C\text{C}), Nitrogen (N\text{N}), Oxygen (O\text{O}), Fluorine (F\text{F}), and Neon (Ne\text{Ne}) are non-metals.

Therefore, there are only 22 metals in the second period.

Common Mistakes

  1. 1Including Boron as a metal, whereas it is actually a metalloid.
  2. 2Confusing the second period with the second group.

Interesting Facts

Lithium is the lightest known metal and is so soft that it can be easily cut with a knife, as highlighted in the NCERT text.
