Which of the following descriptions of the electron dot structure corresponds to an element in the s block?
A. has three unpaired dots
B. has an unpaired dot
C. has two pairs of dots and two unpaired dots
D. has three pairs of dots and an unpaired dot

Answer:

Option (3) is the correct answer.

Explanation:

The electron dot structure corresponds to an element in the s-block that has an unpaired dot.

  • Electron dot structure tells us about the number of valence electrons in the atom of an element
  • Element in s-block in their electron dot structure has either a single unpaired electron dot or a pair of electron dot.
  • Element in p-block has valence electron equal to their group number minus 10.

So, from this, we can conclude electron dot structure corresponds to an element in the s-block that has an unpaired dot.
