What else can I help you with?
Rutherford concluded from his calculations that the volume of an atom is?
Mainly empty space, with a very small and dense nucleus at the center containing the majority of the atom's mass.
Which of these statements is true of atomic nuclei.they are very dense.. they contain electrons..they are mostly empty space..they have a neutral charge?
Atomic nuclei are very dense, as they contain protons and neutrons tightly packed together. They do not contain electrons, as electrons orbit around the nucleus. Although nuclei are very small in comparison to the overall size of an atom, they are not mostly empty space. Nuclei typically have a positive charge due to the presence of protons.
Rutherfords gold foil experiment showed that the atomic nucleus is?
very small relative to size of whole atomextremely densehighly positively charged
A sentence for nucleus?
Example sentence - At the center of an atom is the very dense region called the nucleus.
Rutherford's experiment included bombarding thin gold foil with alpha particles based on this research he concluded that?
Rutherford concluded that the atom is mostly empty space with a small, dense nucleus at the center. He also proposed the nuclear model of the atom, where electrons orbit the nucleus in a mostly empty space. This experiment laid the foundation for the modern understanding of atomic structure.
What is nucleus of an atom?
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.
Is the very small dense center of an atom?
Nucleus
Rutherford concluded from his calculations that the volume of an atom is?
Mainly empty space, with a very small and dense nucleus at the center containing the majority of the atom's mass.
Elaborate on what the nuclear model of the atom indicates about the volume in the atom.?
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.
Why the nucleus is very dense?
Because more than 99 % from the mass of an atom is concentrated in the nucleus (protons + neutrons).
What is the nucleus of an atom?
It contains protons, and SOME also contain neutrons.
What did Rutherford discover about the volume of the nucleus?
Rutherford discovered that the nucleus occupies a very small volume compared to the overall size of the atom. He found that the nucleus is extremely dense and contains nearly all the mass of the atom, while the rest of the atom is mostly empty space.
Is the nucleus a very small region of the atom?
No, the nucleus is a relatively small region located at the center of an atom. It contains protons and neutrons, while electrons orbit around the nucleus in the electron cloud. The nucleus contributes most of the atom's mass and has a positive charge.
Is an atom large?
An atom is very small the human eye can not see an atom that is what makes it small.
Describe the experimental basis for believing that the nucleus occupies a very small fraction of the volume of the atom?
The experimental basis for believing that the nucleus occupies a very small fraction of the volume of the atom comes from the results of the Rutherford gold foil experiment. In this experiment, alpha particles were fired at a thin gold foil, and most particles passed straight through, indicating that the nucleus, where most of the atom's mass is concentrated, is very small compared to the overall size of the atom. This led to the development of the planetary model of the atom, where electrons orbit a small, dense nucleus.
Is atom small?
Yes VERY small
What is the initial state of the universe according to the big bang theory?
Very small, very dense, very hot. Basically, all the matter that is currently in the Universe was initially concentrated in a space smaller than an atom.
