“Did Adam name the serpent like he named all the other animals? This would also show that he understood the nature of the serpent. He either named all the animals or he did not.”

that’s a good point of Scripture to show that Adam knew the serpent was going to be sneak/crafty that Eve would not have known. And then that brings in the question of how much influence did Satan give to the serpent and the the serpent was inclined to readily receive the sort of influence Satan would give it.
