The nucleus of an atom is the central core where protons and neutrons are located. It is very dense and contains most of the mass of the atom. Electrons orbit around the nucleus in specific energy levels.
The tiny very dense body located in the atom's center is called the atomic nucleus. It contains protons and neutrons, which make up the majority of the atom's mass. Electrons orbit around the nucleus in the electron cloud.
Ernest Rutherford concluded that the positive charge of an atom is concentrated in a dense core at the center called the nucleus. This discovery came from his gold foil experiment, where he observed that most of the alpha particles passed straight through the foil, indicating that most of the atom is empty space.
Ernest Rutherford proposed the nuclear model of the atom in 1911, which suggested that an atom consists of a small, dense, positively charged nucleus surrounded by orbiting electrons. This model was based on his gold foil experiment, which demonstrated that most of an atom's mass and positive charge is concentrated in its nucleus.
Rutherford concluded that an atom has a small, dense nucleus at its center, surrounded by orbiting electrons. The nucleus contains positively charged protons, with neutral neutrons also present. This model is known as the nuclear model of the atom.
The very small dense region of an atom is the nucleus. It contains protons and neutrons, which are tightly packed together at the center of the atom. Electrons orbit around the nucleus in the electron cloud.
Mainly empty space, with a very small and dense nucleus at the center containing the majority of the atom's mass.
The nuclear model of the atom suggests that an atom is mostly empty space with a small, dense nucleus at the center. The volume of an atom is therefore primarily occupied by this empty space, with the nucleus accounting for a very small portion of the total volume.

Because more than 99 % from the mass of an atom is concentrated in the nucleus (protons + neutrons).
The center of an atom is called the nucleus. It consists of positively charged protons and neutral neutrons, tightly packed together. The nucleus contains most of the atom's mass in a very small volume.
