Question

Statement I: The most important factor in determining the chemical properties of an element is the number of electrons in the outermost shell.
Statement II: The number of electrons in the outer shell determines the bonding characteristics of the element.

• A. Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1
• B. Both the Statement 1 and Statement 2 are correct and Statement 2 is NOT the correct explanation of Statement 1
• C. Statement 1 is correct but Statement 2 is not correct
• D. Statement 1 is not correct but Statement 2 is correct
• E. Both the Statement 1 and Statement 2 are not correct

Answer 1

The correct option is A Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1

Option $A$ is the correct answer.

The chemical property of an element is determined by the number of bonds it can form with another element. And the number of bonds it can form depends on the number of valence electrons present. Every element wants to get a stable state by forming bonds with other element either by mutual sharing of electrons or transfer of electrons. And only the number of valence electrons will determine its stability.

Thus statement 2 is the correct explanation of statement 1
