What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron?
The question is: What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron?This question may seem hard and/or confusing, but it's really not. You just have to think about it for a minute. This question was in my science quiz online. I had to take LOTS of notes, and guess what?, the answer was right there in my notes..The notes that I took for this question had the topic:Electrons in an ElementMy notes were:-Electrons occupy the electron cloud.-Each electron occupies an energy state.-Electrons farther from the nucleus occupy a higher energy state.-The electron cloud is divided into energy levels.-Each energy level can hold a certain number of electrons-Valence Electrons are usually found in the highest energy level.Not very much notes, but lots of information, and most of them are about energy, and one is about Valence electrons. So, let's figure this.If a valence electron usually have the highest energy level, then a nonvalence electron must not have any energy levels. So, what you would have to add to the nonvalence electron is add energy to become a valence electron.Our question is: What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron?So the answer to our question is: Energy. Energy can be added.
Why do electrons orbit far away from atomic nuclei?
Because of the electromagnetic force. It requires more energy to pull a negatively charged electron further away from the positively charged nucleus.
How does a machine cause you to expend more energy?
If it is inefficient, causing more input then output, or wasteful, eg: a hydrogen converter with a reuptake adapter reusing purified hydrogen but losing the bulk of the material.
Why is high pressure required to cause atomic nuclei to crash into one another in stars?
Extremely high pressure is required to initiate fusion in the stars. This pressure overcomes the normal repulsion between protons, allowing protons of hydrogen to get close enough for the strong atomic force to take over and change the force to an attractive force, forming helium.Not stated, but answered for completeness sake... Extremely high temperature is also required in order to strip the hydrogen nuclei of their electrons, forming an ionized plasma, in order to get past the additional repulsion that the electron cloud would represent.
What happens when an electron emits a photon?
When an electron absorbs a photon, the energy it gains can cause it to change orbitals. The result is ionization. The electron can then emit a photon in the process of "falling back" into its original orbit. Note that electrons won't absorb a photon that cannot give them enough energy to reach a higher orbital. There are no "half measures" in this aspect of quantum mechanics as electrons cannot be shifted "half way" to the next higher orbital. The proof of the pudding here is that we can use lasers of a given frequency to stimulate the electrons in orbit around given atoms. By knowing how much energy a certain electron needs to move to the next higher orbital, we can tune our laser to that photonic energy. Then when we point our laser at a bunch of these atoms, we'll see a bunch of electrons being kicked up to higher orbitals and then emitting photons to return to their previous orbital. There is a bit more to this, but the essentials are here, and are a first step to understanding the subtle ways photons and electrons interact.
Which principal energy level change by the electron of a hydrogen atom will cause the greatest amount of energy to be absorbed?
n=2 to n=5 , hope that helps
What happens when a hydrogen atom absorbs a quantum of energy?
When an atom looses energy a photon (particle of light) is produced with energy equivalent to the energy lost by the atom. In this way we still hold conservation of energy. The fact that energy is quantised means that only certain electron orbits can exist. This is because it is the orbit of the electron which generally holds an atoms energy (at least in this case), so an electron can only stay in quantised orbits. Quantised orbits solved blackbody radiation and provide an insight into chemistry. A solution to the black body radiation problem is the most significant outcome of applying quantum mechanics to the atom. Without it an atom would continously emit energy as the electron spirals towards the nucleus. This is because classically an accelerating charge in a field, like an electron, must give of energy. In a quantum system the energy cannot be given off except in quanta. The way i view it is more like the electron occupies a probability bubble and is not really moving or accelerating at all.
What makes electron change from high energy to low energy?
cause it does
Why is hydrogen set by itself?
Hydrogen consists of just one proton and one electron (the cause of why hydrogen behaves unlike any other element) because of this hydrogen is in a class alone in the Periodic Table of elements.
Does the reaction that separates water into hydrogen and oxygen absorb or release energy?
Endothermic reaction is the breakdown of water into hydrogen and oxygen and this cause for energy to be absorbed
Can an electron jump from sixth shell to second shell?
yes. in the case of hydrogen atom jumping of an electron from 6th level to 2nd level cause balmer series

What is the group trend in the first ionization energies and why?
1. The ionization energy decrease down in the group.2. The cause is that the distance between the nucleus and the electron shell increase and the needed energy to extract an electron decrease.
Which is the cause of the sun energy?
Nuclear fission is the source of the sun's energy. It is a process in which an atom of hydrogen fuses with another atom of hydrogen, releasing large amounts of energy in the process. It is quite the opposite of nuclear fission, which is the source of atomic energy.
Why the bond energy of HF is greater than HBr?
Fluorine has the highest electronegativity of any element. Therefore, the energy released when hydrogen and fluorine react is greater than the energy released when hydrogen and bromine react, and that energy must be resupplied to cause either bond to break.
How does the quantum-mechanical model differ from Bohrs model?
Bohr's model explains how electron transitions cause hydrogen's atomic emission spectra. The quantum model is a 3-d view of the atom, which shows an electron's energy levels and sublevels and the probability of an electron's location, proven with complex mathematics.
What happens when a proton and an electron come close to each other?
They might 'form' a new atom named hydrogen.
