The ground state electronic configuration of the elements, U, V, W, X, and Y (these symbols do not have any chemical significance) are as follows:
`U" "1s^(2)2s^(2)2p^(3)`
`V" "1s^(2)2s^(2)2p^(6)3s^(1)`
`W" "1s^(2)2s^(2)2p^(6)3s^(2)3p^(2)`
`X" "1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(5)4s^(2)`
`Y" "1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(10)4s^(2)4p^(6)`

The correct Answer is:
To solve the problem, we need to analyze the ground state electronic configurations of the elements U, V, W, X, and Y, and determine which element corresponds to each of the four statements provided. ### Step-by-Step Solution: 1. **Identify the Elements from Electronic Configurations:** - **U:** `1s² 2s² 2p³` corresponds to Nitrogen (N), atomic number 7. - **V:** `1s² 2s² 2p⁶ 3s¹` corresponds to Sodium (Na), atomic number 11. - **W:** `1s² 2s² 2p⁶ 3s² 3p²` corresponds to Silicon (Si), atomic number 14. - **X:** `1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁵ 4s²` corresponds to Manganese (Mn), atomic number 25. - **Y:** `1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶` corresponds to Krypton (Kr), atomic number 36. 2. **Determine Which Element Forms a Carbonate That Does Not Decompose by Heating:** - Group 1 elements (alkali metals) form carbonates that do not decompose upon heating, except for lithium. Sodium (V) is an alkali metal. - **Answer:** Sodium (V). 3. **Identify the Element Most Likely to Form a Colored Ionic Compound:** - Transition metals typically form colored compounds due to d-d transitions. Manganese (X) is a transition metal. - **Answer:** Manganese (X). 4. **Determine Which Element Has the Largest Atomic Radius:** - Atomic radius increases down a group and decreases across a period. Krypton (Y) is a noble gas and has a larger Van der Waals radius compared to the others. - **Answer:** Krypton (Y). 5. **Identify the Element That Forms Only Acidic Oxides:** - Nonmetals generally form acidic oxides. Silicon (W) is a nonmetal and forms SiO₂, which is acidic. Nitrogen (U) forms both acidic and neutral oxides, so it does not qualify. - **Answer:** Silicon (W). ### Summary of Answers: - (i) Sodium (V) - (ii) Manganese (X) - (iii) Krypton (Y) - (iv) Silicon (W)
