turn: 1
modality: image
input: Generate a single element box from the periodic table for the element that meets the following criteria: It is a soft, silvery-white, highly reactive alkali metal. It is the most abundant alkali metal in the Earth's crust and its cation is the primary extracellular cation in biological systems. The box should contain: the correct element symbol in the center, and the correct atomic number in the top-right corner.
output: evaluation_points: 1. The generated content should generally resemble a single, isolated box from a standard periodic table (e.g., rectangular shape, clean borders).

2. The element symbol 'Na' must be correctly and prominently displayed in the center of the box.

3. The atomic number '11' must be correctly and clearly displayed in the top-right corner of the box.

4. The image should be simple, flat in style, and contain no other content besides this single periodic table element box.

turn: 2
modality: text
input: Based on the element symbol and atomic number from the input image, consider the following: If this element can combine with chlorine (Cl) to form a compound, and this compound has the following properties: It is a white crystalline solid at room temperature, highly soluble in water, and its aqueous solution conducts electricity. It is the primary component of table salt. What is the most likely compound formed?
Options:
A. Sodium Hydroxide (NaOH)
B. Sodium Chloride (NaCl)
C. Sodium Carbonate (Na2CO3)
D. Sodium Sulfate (Na2SO4)
E. None of the above
output: answer: B

turn: 3
modality: image
input: Generate a test tube containing an aqueous solution of the target substance you identified in the previous question (sodium chloride). After adding a few drops of reagent B = Silver Nitrate solution (AgNO3), a precipitate forms inside the test tube. The precipitate is white and curdy. The background should be a simple laboratory bench.
output: evaluation_points: 1. The test tube and liquid volume should be reasonable, with the liquid level at approximately one-third of the test tube's height.

2. The color of the precipitate must be white.

3. The state/morphology of the precipitate should be curdy or clumpy, not a fine powder or crystalline.

4. The solution color should be reasonable. After the precipitation reaction, the solution should remain colorless and clear, as the reaction between sodium chloride and silver nitrate produces a white precipitate and a colorless sodium nitrate solution.

The image background should be a simple, clean laboratory bench. This is a new requirement for this turn.

turn: 4
modality: text
input: According to the precipitation phenomenon shown in the input image, if an 'excess' amount of reagent C = Dilute Nitric Acid (HNO3) is added to the test tube and the mixture is allowed to stabilize, what is the most likely observation?
Options:
A. The white precipitate dissolves completely, resulting in a clear, colorless solution.
B. The white precipitate partially dissolves, forming a cloudy suspension.
C. The white precipitate remains unchanged; no visible reaction occurs.
D. The white precipitate changes color to yellow or brown.
E. None of the above
output: answer: C
