23. As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit increase or…
16. If an electron has absorbed energy and has shifted to a higher energy level, the electron is said to be in an…
But Niels Bohr looked into this and found out that electrons move in paths around the nucleus. Surprisingly these electron can move from one path to another. They can also jump to a path that is a level above. Bohr created a model called the planetary model. This model shows how the electron move in different energy levels.…
When atoms absorb energy, electrons move into higher energy levels, and these electrons lose energy by emitting light when they return to lower energy levels. Energy levels are fixed energies that electrons can have. Ordinary light is made up of a mixture of all the wavelengths of light. Light, consisting of waves consists of wavelength and frequencies that are inversely proportional to each other, so as the wavelength of light increases,…
Introduction: According to the Bohr atomic model, electrons orbit the nucleus in fixed paths with specific energies. Each path is therefore often referred to as an “energy level”. Electrons possessing the lowest energy are found in the levels closest to the nucleus. Electrons of higher energy are located in progressively more distant energy levels.…
In the Energy Story, the author tells us that we use a lot of energy and in a lot of different things. They tell us how the structure of the atom looks and how the number of protons, electrons, and neutrons affect how much energy that element can produce. If there are more electrons the element does not conduct any energy and if there are more…
Research the construction of major building project (using the list below) and explain how both the earth’s interior and exterior forces impacted the building project. Place your findings into a 1-2 page informal writing.…
By placing atoms of a metal into a flame, electrons can be induced to absorb energy and jump to an excited energy state, this is called a quantum jump. They then return to their ground state by emitting a photon of light. The amount of energy in the photon of light determines its color. For example, when a photon gives off red light, you can determine that it does not have a lot of energy because red light is the lowest of visible light on the electromagnetic spectrum. Opposite to that, violet light would have the most amount of energy because it is higher up on the electromagnetic spectrum, which is because it has shorter…
When atoms or ions in the “ground state” are heated to high temperatures, some electrons may absorb enough energy to allow them to “jump” to higher energy levels”(Barberton High School,para 4). All electrons reside in energy levels. Electrons want to be stable, or in the ground state. But when electrons absorb enough energy, for example an electron absorbing energy from a heat source they get excited. When they get into the “excited” state the electrons tend to jump into higher energy levels.…
Neil Bohr created the planetary model, which had orbits around the nucleus. This was created because Rutherford’s assumption of electrons being in the inside of the atom by the nucleus was incorrect. The electrons are negatively charged while the nucleus was positively charged and opposites attract. Although, these two were not attracting so then Bohr realized that the electrons were on the outside of the nucleus and created a model to display this.…
Initially, physics was a term used to describe the study of matter and its motion through space and time, occasionally including energy and force. However, in 1900 Max Planck a German Physicist presented the beginning of his Quantum Theory. Since this time studies have commenced on the nature and behaviour of matter and energy on the atomic and sub atomic level. While it is highly unlikely to see these natures directly without scientific equipment, the effects and changes that occur are known as a paradigm shift and can be acknowledged in everyday life. One example of this is the subatomic structure in relation to light.…
Bohr proposed that an electron is found in specific circular path, or orbits, around the nucleus.…
In the famous novel The Strange Case of Dr. Jekyll and Mr. Hyde there are many underlying themes surrounding the story line. The story takes on a dark and mysterious aspect that seems to allude to something more then what it is letting on. One major theme that I saw throughout the entire story was addiction or substance abuse. The dual personality of Jekyll and Hyde is unnatural and their actions make the reader believe that there is a serious problem going on. The novel Dr. Jekyll and Mr. Hyde illustrates the different behaviors and symptoms of addiction and substance abuse.…
As a person in science, i should know the order of colours in the visible spectrum and the span of visible wavelengths.…
