This was an idea of Ernest Rutherford (1871-1937) from 1911.
What else can I help you with?
What did Rutherford picture an atom as?
Rutherford pictured an atom as a small, dense, positively charged nucleus surrounded by orbiting electrons. He proposed this nuclear model based on his gold foil experiment, which showed that most of the atom's mass and positive charge is concentrated in the nucleus.
Where in a atom are protons found?
Protons are found in the nucleus of atoms along with the neutrons of the atom. The nucleus is always in the centre of the atom.
What is an atom of a hydrogen that does not have a nucleus?
Without a nucleus it can not be either an atom or hydrogen.
Where is the location for a proton?
it is located in the nucleus and are positvly charged
Which subatomic particle are found in the nucleus of an atom?
Protons and neutrons are found in the nucleus of an atom.
Rutherfords alpha scattering experiment showed that the charge on the nucleus of the atom must be?
Rutherford's alpha scattering experiment showed that the charge on the nucleus of the atom must be positive because the alpha particles were deflected by the concentrated positive charge in the nucleus.
Rutherfords alpha scattering experiments showed that the charge on the nucleus of the atom must be?
The atomic nucleus is positive because contain protons.
Rutherfords gold foil experiment showed that the atomic nucleus is?
very small relative to size of whole atomextremely densehighly positively charged
Rutherfords gold foil experiment led to the discovery of the?
Nucleus - Rutherford fired particles at gold foil, and most went straight through. This showed that most of atoms are empty, and that most of the mass only occupies a small part of the atom. This part is known as the nucleus.
What is the dense center of the atom called?
the denser part of an atom is the nucleus. about 99% of the mass of an atom is concentrated within the atom.
Which model showed the discovery of a positively charged nucleus?
The Rutherford model was the model that showed the discovery of a positively charged nucleus. In this model, proposed by Ernest Rutherford in 1911, he suggested that atoms have a dense, positively charged nucleus at the center, with electrons orbiting around it. This model provided evidence for the nuclear nature of the atom.
What is the center of an atom called?
The center of an atom is called a nucleus (nucleifor plural).Center of an atom is called the "Nucleus".
Rutherford's alpha-scattering experiment showed that the charge on the nucleus of the atom must be a.positive b.neutral c.negative d.too small to be detected?
positive

What part of an atom forms a nucleus?
The nucleus forms the centre of the atom. The protons and neutrons are found in the nucleus of the atom.
Most of the mass of an atom is concentrated in the?
in the nucleus of the atom
Center of atom?
The center of an atom is the atomic nucleus.
