Who said that an atom has a small positively charged nucleus surrounded by a large region?
ernest rutherfold
What else can I help you with?
What is the positively charged central region or core of an atom called?
NUCLEUS ---------------------------------------------------------------------- In an atom, there are three subatomic particles. Two of them are found in the central region known as the nucleus: the proton, which is positively charged and neutron that does not have a charge. Another region, containing the negatively charged electron, is known as a cloud, an electron cloud if you want.
What did rutherford's gold foil experiment show?
Rutherford's gold foil experiment showed that atoms have a small, positively charged nucleus at the center, surrounded by mostly empty space where electrons orbit. This disproved the "plum pudding" model of the atom and led to the development of the planetary model of the atom.
Central region of an atom?
The central region of an atom is the nucleus, which contains protons and neutrons. Protons have a positive charge, while neutrons have no charge. The nucleus is surrounded by a cloud of electrons, which have a negative charge and orbit the nucleus in different energy levels.
Rutherford's gold foil experiment provided evidence for what?
In 1911, Rutherford decided to experiment using what was the current theory of atomic structure at the time. Based on his results, he proposed a new theory; that the majority of the atom is empty space, and that all of the positive and most of the mass are contained in a small central region within the atom, which became later known as the nucleus.
What experiment convinced ernest ratherford that the atom has a smallpositively charged nucleus?
The Rutherford gold foil experiment convinced Ernest Rutherford that atoms have a small positively charged nucleus. In this experiment, a beam of alpha particles was directed at a thin gold foil. Most of the alpha particles passed through the foil, but some were deflected at large angles, showing that the positive charge of the atom is concentrated in a small region (the nucleus) within the atom.
Who said an atom has a small positively charged nucleus surrounded by a large region in which scientist can predict where an electron is likely to be found?

What is the atom as having a small positively charged nucleus surrounded by large region where there are enough electrons to make the atom neutral?
No because the electron are small and don't have enough of energy to make atom neutral
What is Ernest Rutherford's contributions to the atomic sturcture?
Rutherford's famous gold foil experiment disproved Thompson's "plum pudding" model of the atom, and instead suggested a small, central, positively charged region (the nucleus) surrounded by a cloud of negatively charged electrons.

What is the center of an atom is dense region consisting of proton and neutron is called?
The dense region at the center of an atom, consisting of protons and neutrons, is called the atomic nucleus. It contains the majority of the atom's mass and is positively charged due to the presence of protons. Electrons orbit around the nucleus in the electron cloud.
Can polar molecules have regions of charge?
Not only can they, they must. At least one positively charged region and at least one negatively charged region.
What are the atomic structures?
All atoms consist of two regions. The nucleus is a very small region located near the center of an atom. In every atom the nucleus contains at least one positively charged particle called a proton and usually one or more neutral particles called neutrons. Surrounding the nucleus is a region occupied by negatively charged particles called electrons. This region is very large compared with the size of the nucleus. Protons, neutrons, and electrons are often referred to as subatomic particles.
Why do electrons circle the nucleus?
Electrons circle the nucleus in specific energy levels due to the forces of attraction between the positively charged nucleus and the negatively charged electrons. This motion is described by quantum mechanics as electron orbitals, which represent the probability of finding an electron in a particular region around the nucleus.

Protons, neutrons, and electrons are often referred to as subatomic particles.
Which does not described the relationship between the nucleus and the electron cloud of an atom?
The nucleus is the central core of an atom that contains protons and neutrons, while the electron cloud is the region surrounding the nucleus where electrons are found. They are connected by the attraction between the positively charged protons in the nucleus and the negatively charged electrons in the electron cloud.
