According to scientist Rutherford, in the core of an atom is a positively charged nucleus and the nucleus is surrounded by negatively charged electrons.
Rutherford
Ernest Rutherford was the man you are thinking of. He was the first person to 'split the atom'.
Ernest Rutherford is the scientist who envisioned the atom as a ball of positive charge with electrons embedded in it. This model became known as the Rutherford model of the atom.
THE FIRST SCIENTIST WAS RUTHERFORD.
It is the scientist Rutherford. He proposed it in year 1919.
Bohr-Rutherford
A nucleus
Ernest Rutherford is the scientist who proposed that most of the mass of an atom is concentrated in a small, dense, positively charged nucleus, based on his gold foil experiment which led to the discovery of the atomic nucleus.
The structure of the atom was discovered by Ernest Rutherford and Niels Bohr. Rutherford's gold foil experiment led to the discovery of the nucleus, while Bohr proposed the planetary model of the atom with electrons orbiting the nucleus in specific energy levels.
Rutherford discovered the atomic nucleus and the proton. A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
There were four scientists that discovered the atom. These scientist were John Dalton, William Crooke, J.J. Thomson and Ernest RuthThere were four scientists that discovered the atom. These scientist were John Dalton, William Crooke, J.J. Thomson and Ernest Rutherford.
