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 is the wave model?
The modern atom model that has a small positively charged nucleus surrounded by a large region in which there are enough electrons to make the neutral It has energy level on the outside with electrons on it negatively charged and the same number always of the protons which is the atomic number on the periodic table) and there can be only up to a certain amount of electrons on each energy level, 2 for the 1st, 8 for the second a nucleus that has protons and neutrons inside. The protons is equal to the atomic number and is the same number of electrons and is positively charged. The neutron has no electrical charge and are the particles that keep the protons from bouncing of each other and is the atomic mass found on the periodic table minus the number of electrons or protons. The protons (positive) attract to the electrons negative and the neutrons make the atom neutral
How did Rutherford explain the results of his gold foil experiment?
Rutherford made the following conclusions:Since most of the alpha particles passed straight through the gold foil without any deflection, most of the space within the atoms is empty.Since some of the alpha particles (which are big in size) were deflected by large angles or bounced backwards, they must have approached some positively charged region responsible for the deflection. This positively charged region is now called the nucleus.As very few alpha particles undergone the deflection, it was concluded that the volume occupied by the central region ( nucleus ) is very small.Since alpha particles which are relatively denser, were deflected by the central volume of charge, it shows that almost the complete mass of the atom must be within the central volume.
Central region of an atom?
Nucleus.
What is Rutherford's experiment with gold foil and alpha particles?
The initial discovery of "Rutherford Scattering" was made by Hans Geiger and Ernest Marsden in 1909 when they performed the gold foil experiment under the direction of Rutherford, in which they fired a beam of alpha particles (helium nuclei) at layers of gold leaf only a few atoms thick. The intriguing results showed that around 1 in 8000 alpha particles were deflected by very large angles (over 90°), while the rest passed straight through with little or no deflection. From this, Rutherford concluded that the majority of the mass was concentrated in a minute, positively charged region (the nucleus) surrounded by electrons. When a (positive) alpha particle approached sufficiently close to the nucleus, it was repelled strongly enough to rebound at high angles. The small size of the nucleus explained the small number of alpha particles that were repelled in this way.

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.

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.
