Nucleus of An Atom
The nucleus of an atom is a dense region consisting of protons and neutrons. The nucleus is found in the center of an atom. More than 99% of the atom's mass is found in the nucleus.
Nucleus of a Cell
A cell's nucleus contains much of the genetic material. Most people think of the nucleus as the "brain" of a cell. Inside the nucleus is the nucleolus, which produces ribosomes.
The subatomic particle that fits this description is the electron. Electrons have a negative charge, are found outside of the nucleus in electron shells, and have a very small mass compared to protons and neutrons.
An atom is organized with a nucleus at its center, containing protons and neutrons. Electrons orbit the nucleus in specific energy levels or shells. The nucleus is positively charged, while electrons are negatively charged, creating a stable, neutral atom.
No element could possibly fit this description. There are WAY too many electrons and no where near 201 particles in the nucleus.
The center of the atom, where protons and neutrons are located, is called the nucleus. It contains most of the mass of the atom and is positively charged. The electrons orbit around the nucleus in energy levels.
Bohr hypothesized that electrons orbit the nucleus of an atom in specific energy levels or shells, and that they can jump between these levels by absorbing or emitting energy. This led to the development of the Bohr model of the atom, which provided a more accurate description than previous models.

The nucleus is the organelle that controls all the activities within the cell.
The nucleus is the organelle that controls all the activities within the cell.
At the simplest level of description, a nucleus contains protons and neutrons.
Messenger RNA
The nucleus is in the center of the lens, the cortex surrounds the nucleus, and the capsule is the outer layer.
The main scientist was Robert Brown. He made a detailed description of the cell nucleus and he also gave nucleus it's name
The electron orbits AROUND the nucleus (center).
Bohr's description of an atom: an atomic nucleus positive surrounded by nedative electrons placed on predetermined orbits.
It is the protoplasm outside the nucleus of a cell.
alpha radiation consists of 2 protons and 2 neutrons. It comes from the nucleus of an atom.
