What scientist showed that most of the mass and positive charge of an atom is concentrated in its center?
Ernest Rutherford demonstrated through his famous gold foil experiment that atoms have a dense, positively charged nucleus at their center. Most of the mass and positive charge of an atom is concentrated in this nucleus, with electrons orbiting around it.

What scientist discovered that atoms have a positive charge?
Ernest Rutherford is the scientist who discovered that atoms have a positive charge. Through his gold foil experiment, he found that atoms have a small, positively charged nucleus at their center, surrounded by negatively charged electrons.
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.
What scientist envisioned the atom as a ball of positive charge with electrons embedded in it?
Ernest Rutherford is the scientist who envisioned the atom as a ball of positive charge with electrons embedded in it. This model became known as the Rutherford model of the atom.
What are the field lines for a positive charge?
The field lines for a positive charge are radial lines extending outward in all directions from the charge. The field lines indicate the direction of the electric field, pointing away from the positive charge. The field lines are more concentrated closer to the charge and spread out further away.
How was Rutherford's gold foil experiment inconsistent with the plum pudding model of the atom?
Rutherford's gold foil experiment disproved the plum pudding model by showing that atoms have a small, dense nucleus at their center, rather than being uniformly filled with positive charge. The experiment revealed that most of the alpha particles passed straight through the foil, indicating that atoms are mostly empty space with a concentrated positive charge at the center. This contradicted the plum pudding model, which proposed that positive charge was evenly distributed throughout the atom.
Is positive charge spread equally over an atom?
No, positive charge is concentrated in the nucleus of an atom, which contains protons. Electrons, carrying negative charge, are located in energy levels surrounding the nucleus. The positive charge of the protons is concentrated at the center of the atom.
Who atomic model determined that an atoms positive charge is concentrated in the atoms center?
The Rutherford model proposed that an atom's positive charge is concentrated in a dense center called the nucleus. This model was based on the famous gold foil experiment conducted by Ernest Rutherford in 1909.

Who discovered the positive charge of a nucleus?
Ernest Rutherford is credited with discovering the positive charge of a nucleus through his famous gold foil experiment in 1909. This experiment showed that most of the mass and positive charge of an atom is concentrated in a small, dense nucleus at its center.
What is the charge of the center an atom?
The center or Nucleus always carries a Positive Charge
What is the positive charge in an atomic model?
The proton has a positive charge, +1.

Who was the scientist responsible for discovering the nucleus of the atom?
Ernest Rutherford is credited with discovering the nucleus of the atom through his gold foil experiment in 1909. He observed that most of the particles passed through the foil, suggesting that the atom is mostly empty space with a concentrated positive charge at the center, which he called the nucleus.
What is the charge inside center of an atom?
positive

Ernest Rutherford is the scientist who envisioned the atom as a ball of positive charge with electrons embedded in it. This model became known as the Rutherford model of the atom.
What has a positive charge and found in the center of an atom?
A proton.
Where did the positive charge in an atom was located?
The center, the nucleus.
