What is the basic difference between electron affinity and electro negativity?
ok, so electron affinity is the amount of energy given off when a particular atom excepts electrons. Essentially, it is the likelihood that an atom will accept an electron, while ionization energy is how much energy is needed to take an electron off of a particular atom
What energy is needed to remove an electron from its outer most shell?
This is called the ionization energy and an is different for each electron in the atom. Electrons in the outer shell (furthest from the nucleus) have the lowest ionization energy, electrons in the innermost shell (closest to the nucleus) have the highest ionization energy.
Does the addition of two electrons or removal of one electron require more energy for an oxygen atom?
when adding two electrons to the oxygen atom yep! it requires more energy because it has to take them from another atom so it will be removing an electron using more ionization energy to do the work.and we must remember that oxygen needs two electrons to attain its valency then it needs to take two from another atom to be fully filled and without the two electrons it will still lack electron to be stable.this means adding or removing requires energy.
It takes 208.4 kJ of energy to remove 1 mole of electrons from an atom on the surface of rubidium metal How much energy does it take to remove a single electron from an atom on the surface of solid r?

How do you charge atoms into an ion?
You take an electron from an atom, or force one into it

Can atoms be ionized by being excited?
No. When you excite an atom, you just do something with the electrons within the atom. (You take them into higher energy levels.) An atom can be ionized only when it is charged, you would have to remove or add an electron. But you are only placing the electron on higher energy level, so it stays within the atom, therefore atom is not ionized.

How would a atom react with a low ionization energy?
It would not take a great deal of electronegativity to pull at least the first electron off this atom.
Which energy transition may take place in the atom if its electron has absorbed a photon?
n=3 to n=2
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.
Which electron in an atom take part in chemical bonding what are they called?
outer energy level electrons... called valence electrons
What electron in an atom take part in chemical bonding what are they called?
outer energy level electrons... called valence electrons
Is ionization an exothermic or endothermic process?
Endothermic...... because it requires energy to take out an electron from the outer orbit of an atom.
