Is the helium ion positive or negative?
If one electron has been removed from Helium's electron shell then it is a He+ ion. If both of its electrons have been removed it becomes a He2+ ion. Either way they are both positive ions.
Where do you get ion from?
Ionic bonds form as a result of the attraction between positive and negative ions. When an atom loses an electron, it loses a negative charge and becomes a positive ion. When an atom gains an electron, it gains a negative charge and becomes a negative ion.
Why 2nd ionization potential is greter than 1st ionisation potential of element?
In the first ionization an electron is removed from a neutral atom. In the second ionization an electron is removed from a positively charged ion. Since electrons carry a negative charge and opposite charges attract it is more difficult (i.e. takes more energy) to remove.
What particle can be removed from an atom easily?
Electron.
When an electron is removed from an atom it i considered what?
The atom is then considered an ion :)
An electron requires 4.4 x 10-19 J of energy to be removed from its atom What is the wavelength of a photon that has this much energy?
450 nm
An electron requires 4 x 10-17 J of energy to be removed from its atom What is the wavelength of a photon that has this much energy?
4.8 - 5.2 nm
That An electron requires 4 times 10-17 j of energy to be removed from it's atom what is the wavelength of a photon that has this much energy?
The wavelength is w = hc/E = .2E-24/4E-17 = 5E-9 meters.
Why does Be have a much larger second ionization energy than the first?
The energy to remove 1 electron is the first ionization energy. To remove a second electron requires more energy. This is because the electron being removed now has to overcome the +1 positive charge introduced after the 1st electron was removed.
What is ioninc bonding?
It is a chemical process whereby one or more electrons from one atom are removed and attached to another atom. This will create a negative charge in the atom from which the electron(s) have been removed, and a positive charge in the atom to which the electron(s) have become attached, resulting in a positive to negative attraction between the two atoms, which will then bond to form a molecule.

What is removed when ionization energy is applied?
an electron
Why the addition of two electrons or removal of one electron requires more energy in oxygen atom?
Type your answer here... when adding an electrons to oxygen it needs more energy in electron affinity in order to attract electrons from other atoms to be stable.and we know that oxygen is in short of two electrons.so in the other hand when an electron is removed from oxygen it will be unstable and will be needing more ionization energy to be able to remove an electron to it.Thus mean indeed when adding or removing electrons for oxygen it requires energy.

Electron.
If enough energy was added to remove an electron for calcium which energy level would the electron be removed?
The 3s.
