No, oobleck is trying to get Eren to do some thinking, not just provide answers.
A major problem these days is trying to get students to think.
a. alkali metals and halogens
An element is highly conductive, highly reactive, soft, and lustrous. The element most likely belongs to which group
well, the alkalis are one set, getting more violent as you go down the column.
so, what else, do you think?
ever consider google?
