Who proposed the Bohr Model? - Niels Bohr
Niels Bohr proposed the Bohr Model of the atom in 1913.
What is the Bohr Model used to describe? - The structure and behavior of atoms
The Bohr Model is used to describe the structure and behavior of atoms, specifically focusing on the arrangement of electrons within the atom's energy levels and the transitions between these levels that result in the emission or absorption of electromagnetic radiation.
What is the central part of an atom in the Bohr Model called? - The nucleus
Yes, that's correct! In the Bohr Model, the central part of an atom is called the nucleus. It contains protons and neutrons, which are surrounded by electrons in specific energy levels or shells.
What subatomic particle is found in the nucleus? - Protons and neutrons
Yes, protons and neutrons are the subatomic particles found in the nucleus of an atom. Protons have a positive electric charge, while neutrons are neutral. These particles are responsible for the majority of an atom's mass.
What orbits or energy levels are electrons arranged in? - Specific, fixed energy levels
Electrons are arranged in specific, fixed energy levels or orbits around the nucleus of an atom. These energy levels are often referred to as shells, where electrons with lower energy occupy inner shells closer to the nucleus, while those with higher energy occupy outer shells farther away from the nucleus.
How are electrons described in the Bohr Model? - As particles moving in circular paths around the nucleus
In the Bohr Model, electrons are described as particles moving in circular paths around the nucleus in specific energy levels or orbits.
What is the maximum number of electrons that can occupy the first energy level in the Bohr Model? - 2 electrons
In the Bohr Model, the maximum number of electrons that can occupy the first energy level is 2 electrons.
How does an electron move from one energy level to another in the Bohr Model? - By absorbing or emitting energy in discrete amounts called quanta
In the Bohr Model, an electron moves from one energy level to another by absorbing or emitting energy in discrete amounts called quanta. These quanta are specific amounts of energy that correspond to the difference in energy between the two energy levels, allowing the electron to transition between them.
What happens when an electron absorbs energy in the Bohr Model? - It moves to a higher energy level away from the nucleus
When an electron absorbs energy in the Bohr Model, it moves to a higher energy level further away from the nucleus. This process is known as electronic excitation and results in the electron being in an excited state. As a result, the electron's orbit around the nucleus becomes larger and less tightly bound.
What happens when an electron emits energy in the Bohr Model? - It moves to a lower energy level closer to the nucleus
When an electron emits energy in the Bohr Model, it moves to a lower energy level closer to the nucleus. This energy emission occurs when an electron transitions from a higher energy level to a lower energy level, releasing the extra energy in the form of a photon.
