What is the dense particle in the center of the atom which contains protons and neutrons?
This is the atomic nucleus.
What is the dense particle in the center of an atom which contains protons and neutrons?
This is the atomic nucleus.
Which statement describes James Chadwicks discovery He discovered that the atomic nucleus is a dense positively charged mass He discovered negatively charged atomic particles that were deflected by a?
an electrical neutral particle from the atomic nucleus
What is the dense particle called?
The dense particle is called a nucleus. It contains protons and neutrons and is located at the center of an atom.
What are the same about what can you say about the charge and mass of the nucleus of an atom?
The nucleus of an atom is positively charged due to the presence of protons, which carry a positive charge, while neutrons are neutral and do not contribute to the charge. The mass of the nucleus accounts for most of the atom's total mass, as protons and neutrons are significantly more massive than electrons. Together, these particles define the nucleus's overall charge and mass, making it dense and central to atomic structure.
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.
Where would a particle with a charge of plus e be found in a atom?
A particle with a charge of plus e, such as a proton, would typically be found in the nucleus of an atom. The nucleus is a dense region at the center of the atom, containing protons and neutrons, while negatively charged electrons occupy the surrounding electron cloud. The positive charge of protons helps to attract and hold the negatively charged electrons in their orbits around the nucleus.
What is true about the atomic nuclei?
The atomic nucleus contain protons and neutrons.
What element is a very dense metal with an atomic mass of 207.2?
The element you are referring to is lead (Pb). It is a very dense metal with an atomic mass of 207.2.
What scientist concluded the nucleus of an atom contains a dense center of positive charge?
Ernest Rutherford is the scientist who concluded that the nucleus of an atom contains a dense center of positive charge. This conclusion was based on the results of his famous gold foil experiment in which he observed the scattering of alpha particles. Rutherford's discovery revolutionized the understanding of atomic structure and laid the foundation for the development of the modern atomic model.
In rutherfords gold foil experiment what particle in dense atomic nuclei caused so alpha particles to bounce straight back from the gold foil?
In Rutherford's gold foil experiment, the alpha particles were deflected back primarily due to the presence of densely packed positive charge concentrated in the atomic nucleus, specifically due to protons. When the high-energy alpha particles, which are positively charged themselves, approached the nucleus, they experienced strong electrostatic repulsion from the protons, causing them to bounce back. This unexpected deflection provided crucial evidence that atoms have a small, dense nucleus at their center, leading to the development of the nuclear model of the atom.
What did Rutherford's backward deflection of alpha particle give evidence of an atom's?
Rutherford's backward deflection of alpha particles in the gold foil experiment provided evidence of an atom's nucleus. The deflection indicated that the majority of an atom's mass and positive charge is concentrated in a small, dense nucleus at its center, with electrons orbiting around it. This discovery led to the development of the nuclear model of the atom.
