Summary of 🔴 MODELO ATÓMICO de THOMSON, RUTHERFORD y BOHR

00:00:00 - 00:05:00

In this section of the YouTube video, the host discusses the Bohr model of the atom, which proposes an atom is made up of a nucleus containing protons and neutrons and an outer cloud-like layer called the electron cloud, where electrons reside. Electrons are only allowed to move in specific, discrete orbits within the electron cloud, each with a specific energy associated with it. The model emphasizes the importance of the electron cloud in shaping atomic structure and behavior, and highlights the importance of the specific energy levels in controlling electrons' movement within the atom.

• 00:00:00 In this section of the YouTube video, the host discusses the model atomic of JJ Thomson, Ernest Rutherford, and Niels Bohr. The model atomic of Thomson proposed that protons, the positively charged particles in an atom, should occupy a larger space in the model. The model atomic of Rutherford, on the other hand, introduced the concept of a nucleus at the center of the atom, with protons and neutrons concentrating their mass and charge there. The model atomic of Bohr went further and proposed that electrons orbit the nucleus in specific energy levels, and that only allowed transitions between levels can occur. The host highlights the importance of each of these models in shaping the modern understanding of atoms.
• 00:05:00 In this section of the video, the speaker is discussing the Bohr model of the atom. The Bohr model posits that an atom is composed of a nucleus containing protons and neutrons, and a cloud-like outer layer called the electron cloud, where electrons reside. Electrons are only allowed to move in certain, discrete orbits within the electron cloud, and each orbit has a specific energy associated with it. When an electron moves from one orbit to another, it emits or absorbs energy, observable in the spectroscopic emission or absorption lines of the atom. The electron cloud is also often referred to as the atom's electron shell, as it suggests that the electrons are arranged in shells or layers around the nucleus, and that each shell has a specific energy level. The speaker concludes by highlighting the importance of this model in understanding atomic structure and behavior.
