The atomic number of an element “X' is 20.
(i) Determine the position of the element 'X' in the periodic table. (ii) Write the formula of the compound formed when 'X' reacts/combines with another element ‘Y' (atomic number 8).
(iii) What would be the nature (acidic or basic) of the compound formed? Justify your answer.

Explanation

To solve the question step by step, we will break it down into three parts as specified in the question.

### Step 1: Determine the position of the element 'X' in the periodic table.
1. **Identify the atomic number of element 'X':** The atomic number is given as 20.
2. **Determine the electronic configuration:** The electronic configuration for atomic number 20 is 2, 8, 8, 2. This means:
- 2 electrons in the first shell (K)
- 8 electrons in the second shell (L)
- 8 electrons in the third shell (M)
