Which statement describes a major drawback of the Bohr model that caused scientists to replace it?
According to the work of the Curies, which action would increase the radioactivity of polonium? Dissolve the polonium in a solvent.Heat the polonium until it becomes a gas.Expose the polonium sample to light.Increase the amount of polonium.
What is the Bohr-Rutherford model of radium?
The Bohr-Rutherford model of radium is a representation of the radium atom where electrons orbit the nucleus in fixed energy levels or shells. The model states that electrons occupy specific energy levels and transition between them by absorbing or emitting energy in the form of photons. Radium has a total of 88 electrons and 88 protons in its nucleus.
Can you display a three dimensional model of a radium atom?
yes - but I don't know how I can show you
What was niel bohrs discovery?
The Bohr model!
Scientist and their conribution to physics?
Albert Einstein - Theory of General Relativity explaining gravity as the curvature of spacetime. Marie Curie - Research on radioactivity leading to the discovery of two new elements, polonium and radium. Isaac Newton - Laws of motion and universal gravitation, laying the foundation for classical physics. Niels Bohr - Quantum theory and atomic structure, proposing the model of the atom with quantized electron orbits. Stephen Hawking - Work on black hole radiation and the nature of the universe, influencing theories of cosmology and quantum gravity.
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 was ptolemys biggest discovery?
Ptolemy's biggest discovery was his geocentric model of the universe, which believed that the Earth was at the center of the universe with planets and stars moving around it in circular orbits. This model dominated Western astronomy for over a thousand years.
How did J.J. Thomson's discovery affect the model of the atom?
J.J. Thomson is credited with the discovery of the electron in about 1904. He envisioned negatively charged "corpuscles" floating in a positively charged cloud, just like plums in a plum pudding. This was the "plum pudding" model of the atom, and it lasted until Geiger and Marsden conducted their gold foil experiment in about 1909.
How does EDRM software is related with E-Discovery?
From information management through production and presentation, the Electronic Discovery Reference Model (EDRM) provides a standardized process for managing electronic discovery
How does the area of the sail affect how quickly a model boat sails?

What led to the discovery of the bohr model?
Neils Bohr discovered it one day
What is the price of the Land Rover Discovery 3?
There are a number of different prices listed for the Land Rover Discovery 3. The price also depends on whether one is in the market to buy a new model or a used or older model.
