What part of the atom does the word nuclear refer to?
A concept or model of the atom characterised by the presence of a small, massive nucleus at its centre.
How did Rutherford's theory change Thomson's theory?
Rutherford's theory significantly altered Thomson's earlier model of the atom by introducing the concept of a dense, positively charged nucleus at the center, surrounded by orbiting electrons. While Thomson's "plum pudding" model suggested that electrons were scattered within a diffuse cloud of positive charge, Rutherford's gold foil experiment demonstrated that most of an atom's mass and positive charge is concentrated in a small nucleus. This shift paved the way for the modern understanding of atomic structure, emphasizing the nucleus's role and leading to the planetary model of the atom.
What De broiglie contribution in atomic theory?
Louis de Broglie's contribution to atomic theory was the concept of wave-particle duality, which proposed that particles, like electrons, could exhibit both wave-like and particle-like behavior. This idea helped to explain some of the strange phenomena observed in quantum mechanics and laid the foundation for the development of quantum mechanics as a field of study.
What was Ernest Rutherford contribution to the atom?
Ernest did an experiment where he shot alpha particles into a gold foil that proved the concept of a nuclear atom,that is an atom with a nucleus made of protons and neutrons and have electrons moving around the nucleus in some way.His experiment did not show the position of electrons or energy levels or even how they moved.
Describe bohr model and how it differ from Rutherford model and how it is similar to Rutherford model?
The Bohr model of the atom describes electrons orbiting the nucleus in discrete energy levels, unlike the Rutherford model where electrons were expected to spiral into the nucleus. Both models incorporate the concept of a centralized positively charged nucleus surrounded by orbiting electrons, though Bohr's model adds the idea of quantized energy levels to explain the stability of atoms.

Ernest Rutherford's contribution to the atomic structure due to the gold foil experiment?
Ernest did an experiment where he shot alpha particles into a gold foil that proved the concept of a nuclear atom, that is an atom with a nucleus made of protons and neutrons and have electrons moving around the nucleus in some way. His experiment did not show the position of electrons or energy levels or even how they moved.
What is the sea of electrons model?
The sea of electrons model is a concept in chemistry that describes the behavior of electrons in metallic bonds. In this model, metal atoms are considered as positive nuclei surrounded by a "sea" of mobile delocalized electrons. These electrons are free to move throughout the metal lattice, giving metals their characteristic properties such as high electrical conductivity and malleability.

What contribution did Aaron Beck make the to the treatment of depression?
Beck developed the concept of the negative triad.
Movement of electrons about a central nucleus is a concept by?
The concept of movement of electrons around a central nucleus is based on the principles of quantum mechanics, particularly the Bohr model and the Schrödinger equation. In this model, electrons occupy specific energy levels or orbitals around the nucleus.
What does chadwick atom model look like?
When James Chadwick discovered the neutron, his discovery led to important revisions in the atom model. Chadwick's work with Ernest Rutherford partly allowed Rutherford to develop a model in which the nucleus consists of two types of nucleons--positively-charged protons and negatively-charged neutrons--surrounded by orbiting electrons.
What is the science concept on Lava lamp?
it is the flow of electrons moving throw the liquid
Explain free electron concept and electric current?
the flow of electrons in semi conductor is called electric current. the electrons revolved around the nucleas is called free electrons
