Do noble gases have high ionization energies?
Yes they do
Can member of different groups have the same ionization energies?
no
Do halogens have high or low ionization energies?
no it does not
How successive ionization energies help us distinguish between core electrons and valence electrons?
Successive ionization energies to provide evidence for arrangement of electrons into core and valence
Do an atom's successive ionization energies increase regularly?
No, an atom's successive ionization energies do not increase regularly. The first ionization energy, which is the energy required to remove the outermost electron, is typically lower than the second ionization energy, which is the energy required to remove the second electron. The ionization energies generally increase as more and more electrons are removed from an atom. However, there can be irregularities due to factors such as electron-electron repulsion and electron shielding.
Out of carbon and fluorine and hydrogen and nitrogen and aluminum which element has the highest value for the first ionization energy?
Fluorine. Ionization energies are a periodic trend and they generally increase as you go up and to the right in the periodic table.See the chart in the Web Links to the left for a complete chart of the ionization energies of all the elements.
What has the highest ionization energies?
Helium.
Both Groups IA and IIA have what ionization?
They both have alkaline ionization energies.
Ionization energies of oxygen and xenon same or not?
No, but they are similar.
Do noble gases have high ionization energies?
Yes they do
Can member of different groups have the same ionization energies?
no
Do halogens have high or low ionization energies?
no it does not
How successive ionization energies help us distinguish between core electrons and valence electrons?
Successive ionization energies to provide evidence for arrangement of electrons into core and valence
What group on the periodic table has the highest ionization energies?
Halogens
Low ionization energies are most characteristic of atoms that are?
electronegativity
Which elements on periodic table have the highest ionization energies?
Helium (He) has the highest ionization energy.
What is group trend in the first ionization energies?
Ionization energies decrease moving down a group, because the shielding effect reduces the pull of the nucleus on valence electrons. Making them easier to remove.
