Question

Name the scientists who were responsible for the following scientific development:
The theory is that atoms consist of small positive nuclei surrounded by electrons.

Answer 1

1. The smallest unit of ordinary matter that makes up a chemical element is an atom.
2. The nucleus of the atom, as described by Ernest Rutherford, is a tiny, massive core.
3. He said that the nucleus is charged positively and the electrons are negatively charged particles.
4. The nucleus is orbited by electrons.

Hence, the theory that atoms consist of small positive nuclei surrounded by electrons is given by the scientist Ernest Rutherford.
