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 Element
My 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.
Metals donate electrons by losing electrons and forming positive ions.
An electron beam makes the object become larger.
8 valence electrons are needed for an element to become stable, which is why the noble gases do not interact with any other elements. They are already stable. However, the exception is Helium, the first noble gas, which only has two valence electrons. 8 valence electrons are needed on the 2nd and 3rd valence shells for any molecule to become stable.
It doesn't really "become" charged. An electron is always charged, and it can only have a charge of -e where value of elementary charge e is 1.602 * 10-19 C as found first by Millikan with his famous oil drop experiment
By gas particles I suppose you mean gas molecules? These become charged when ionized, when an electron is stripped off.
Generally by losing the one electron
there is one valence electron in hydrogen, and it needs one more electron to become stable
When an atom gains or looses a valence electron it becomes a charged particle called an ion
It will become a soft ion.
A negatively charged "ion".
The single valence band electron can easily escape and become a conduction band electron.
It may lose or gain an electron in its valence shell.
they become stable as they have completely filled outermost valence shell and if they have no electron in their outermost shell they become non reactive.
Calcium loses its two valence electrons to become Ca 2+ ion.
11 electrons makes the third energy level complete. One
when sodium valence electron is transferred to chlorine , both atoms become ions . the sodium atom becomes a positive ion . the chlorine atom becomes a negative ion .
