Ernest Rutherford.
Added:
I would think Neils Bohr here.
Clarification: I think it was Rutherford. Bohr's work came after the "Rutherford Model".
There are many places to read about this, eg Wikipedia " Rutherford Model".
Certainly Bohr refined the Rutherford Model even before his quantum ideas for the hydrogen atom. That's why the "planetary model" is sometimes called the "Rutherford-Bohr Model."
The central area of an atom is called the nucleus. It contains protons and neutrons, which are tightly bound together. The nucleus makes up the majority of an atom's mass and is surrounded by a cloud of electrons.
The concept of movement of electrons around a central nucleus is based on the principles of quantum mechanics, particularly the Bohr model and the Schrödinger equation. In this model, electrons occupy specific energy levels or orbitals around the nucleus.
An atom is composed of a single central nucleus, which contains protons and neutrons, surrounded by orbiting electrons.
The statement "An atom consists of a dense nucleus surrounded by a cloud of electrons" is best described as a theory in the field of atomic structure. The atomic theory explains the structure of atoms based on experimental evidence and scientific principles.
The central part of an atom is called the nucleus. It contains protons and neutrons, surrounded by orbiting electrons.
the bohr model
The movement of electrons around the nucleus has been described as orbits ( Bohr molecule) probability cloud (Schroedinger model), electrons being in orbitals
An atom consists of a nucleus containing protons and neutrons, surrounded by electrons in energy levels or shells. The protons and neutrons are located in the nucleus at the center of the atom, while the electrons orbit around the nucleus in specific energy levels.
The movement of electrons around a central nucleus is a concept that was discovered by Niels Bohr in 1913. Bohr's model of the atom revolutionized our understanding of atomic structure and laid the foundation for modern quantum mechanics.

you will need to know how many protons, neutrons and electrons your vanadium atom has. The nucleus, the central part of the atom, all of your atom's protons and neutrons go in the nucleus, The electrons are found outside the nucleus. Depending on which model of atomic structure (Planetary Model, Bohr Model) your are studying your electrons will be placed.
Rutherford proposed that the atom consists of a small, positively charged nucleus surrounded by negatively charged electrons orbiting around it. He conducted the gold foil experiment which led to the discovery of the nucleus and the proton.

The concept of movement of electrons around a central nucleus is based on the principles of quantum mechanics, particularly the Bohr model and the Schrödinger equation. In this model, electrons occupy specific energy levels or orbitals around the nucleus.
The Rutherford-Atomic Theory was published by Ernest Rutherford. It described the atom as having a central positive nucleus surrounded by negative orbiting electrons.
the nucleus is surrounded by electrons, protons and neutrons. Inside the nucleus are quarks. (for the nucleus in an atom only)
An atom is composed of a single central nucleus, which contains protons and neutrons, surrounded by orbiting electrons.
