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.
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.
Why does the separation of an electron from the neutral atom require more enery than the separation of an electron from the anion?
An explanation is via the electron cloud. In a neutral atom, equal number of electrons and protons means a stable separation of electrons from the nucleus and each electron is repulsed by the adjacent electrons at a stable distance. When one electron is removed forming an anion, the electron cloud will move closer to the nucleus because of lower electron repulsion (fewer competitors), and each electron is held more strongly by the protons. Since the force of attraction of proton-electron is stronger than before, removing the second electron will require even more energy than removing the first electron. ==========================
Can an electic charge be removed from a proton or electron?
No. Charge must always be conserved.
What is happening when an electron is removed from the valence shell of a noble gas?
When an electron is removed from the valence shell of a noble gas, it forms a positively charged ion since the number of protons in the nucleus is greater than the number of electrons. This process requires energy and is generally not favored for noble gases due to their stability from having a full valence shell.
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.
If a hydrogen atom loses its electron does it become a negative?
No, if a hydrogen atom loses its electron, it becomes a positively charged hydrogen ion (H+). This is because the electron carries a negative charge, and when it is removed from the atom, the remaining proton in the nucleus gives the atom a net positive charge.
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.
Remove the valence electron from sodium what has happened to the balance of positive and negative charges what is sodium oxidation number?
When a valence electron is removed from sodium, the balance of positive and negative charges becomes uneven, resulting in a positively charged ion (Na+). The oxidation number of sodium in this case is +1.
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.
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.
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 removed when ionization energy is applied?
an electron
If enough energy was added to remove an electron for calcium which energy level would the electron be removed?
The electron would be removed from the outermost energy level, which is the fourth energy level, for calcium.
Why formation of di and tri-negaive ions is endothermic process?
when an electron is added to an atom, uninegative ion is formed and enrgy is released. the addition of one more electron is difficult because negative charge or electronic cloud repels it strongly, to overcome this repelsion an amount of energy is needed, which is obtained by surroundings so its an endothermic reaction.
