GCSE / O Levels Chemistry

Element Y is in Period 3 of the Periodic Table. It forms a chloride that is a liquid at room
temperature.
Which row shows correct information about the group number and the nature of the oxide of
element Y?
A
B
D
group number
I
IV
VI
nature of oxide
basic
acidic
amphoteric
acidic

Choice D is correct because:

Element Y is likely to be sulfur (S). Sulfur is in period 3 and group VI of the periodic table. 

The chloride that sulfur forms, sulfur dichloride (SCl2), is a liquid at room temperature. 

Furthermore, sulfur forms sulfur dioxide (SO2) which is an acidic oxide. 

Choice A is incorrect because Group I elements are alkali metals. They form solid chlorides and basic oxides. Thus, it is not consistent with the description of element Y.

Choice B is incorrect because Group II elements form solid chlorides and basic oxides as well. This also doesn't fit the description of element Y.

Choice C is incorrect because Group IV elements typically form solid chlorides and the oxides can be either acidic, basic or amphoteric depending on the specific element. Therefore, this choice doesn't match the properties of element Y either.
