- pH scale measures from 7
- pH>7 Basic
- pH<7 is acidic

The question is incomplete but i will try to offer as much help as i can.

Explanation:
The electron was discovered by J.J Thompson. His model of the atom was called the plum-pudding model of the atom.
He discovered that cathode rays being negatively charged particles were deflected by a magnet in just the same way as moving, negative electrically charged particles.
Similarly, in an electric field, they are deflected towards the positive plate of the electrostatic field which shows that they are negatively charged.
I believe its A! sugar crystals gently recovered.
C pretty sure if not sorry
