Question

2.) the \staircase\ on the periodic table separates: (1 point)
liquids from gases
gold medals from bronze medals
metals from transition metals
metals from non - metals

Explanation:

The "staircase" (the zig - zag line) on the periodic table is a key feature that separates metals (on the left - hand side of the staircase) from non - metals (on the right - hand side of the staircase). Elements along the staircase are metalloids. The option "Liquids from gases" is incorrect as the periodic table's staircase has nothing to do with states of matter in this way. "Gold medals from bronze medals" is irrelevant to the periodic table. "Metals from transition metals" is wrong because transition metals are a type of metal and the staircase does not separate metals from transition metals.

Answer:

D. Metals from non - metals
