How did Rutherford Discover the Nucleus?

Tracking the composition of matter

Table of Contents In the early 18th century, the atom was considered indivisible. But we know that atoms can be further divided into protons, neutrons, and electrons. JJ Thomson and Ernst Rutherford proved that the atom is divisible by their discovery of the electron and the nucleus. So, how did […]

Osmosis Experiment, Credit: @ghssciofficial Greenford High School Science Osmosis is the movement of water from an area of its lower concentration to its higher concentration across a semi-permeable cell membrane. The addition of salt can change the concentration of water and the osmotic gradient. Salt can help us cook. In
