What elements have the same ionization energy?
None of them do exactly. The elements' ionization energies definitely trend in a couple of ways though. The ionization energy variations tend to decrease as atomic number goes up and tend to increase as you remove more electrons from the atom.
What is isoelectronic with xenon?
Krypton, radon, and xenon cation are all isoelectronic with xenon because they have the same number of electrons.
Why do non metals have higher ionization energies than metal?
Ionization energy is the energy needed to remove an electron. Elements other than transition metals gain or lose electrons from the s and p orbitals in order gain the more stable electron configuration of a Noble gas. Metals lose electrons to become isoelectronic (that is have the same electron configuration) to a noble gas (previous to them in the periodic table), while nonmetals tend to gain electrons in order to become isoelectronic to a Noble gas (next highest on the periodic table). Since ionization energy is the energy needed to REMOVE an electron, it is low for metals which form positive ions by losing electrons to become more stable, but very high for nonmetals that tend to gain, NOT LOSE, electrons. Most transition metals tend to lose electrons as well (other than Rhenium). Transition metals lose electrons from the d orbital, but still form positive ions, so their ionization energy is also usually lower than nonmetals.
What is the formula of the hydride formed by xenon?
Xenon has been formed into two hydrides: xenon dihydride (HXeH), and later xenon hydride-hydroxide (HXeOH). Around the same time xenon was formed into hydroxenoacetylene (HXeCCH).
Which group of elements has very high ionization energies and very low electron affinities?
Group 8 (noble gases) have the highest first ionization energy because they are already stable and don't want to lose any electrons. Ignoring the noble gases, however, group 7 halogens (F, Cl, Br, I, etc.) have the highest first ionization energy. That's because these elements have seven valence electrons, and they don't want to give up any electrons - they want another one!
Can member of different groups have the same ionization energies?
no
Would you expect metals or nonmetals in the same periods to have higher ionization energies?
Non-metals have higher ionization energies within the same period. This is because non-metals want to gain electrons to be able to be like the nearest noble gas.
What elements have the same ionization energy?
None of them do exactly. The elements' ionization energies definitely trend in a couple of ways though. The ionization energy variations tend to decrease as atomic number goes up and tend to increase as you remove more electrons from the atom.
The strontium ion is isoelectronic with xenon is true or false?
True. Both the strontium ion (Sr2+) and xenon (Xe) have the same number of electrons when considering the ionization states: 54 electrons. This means they are isoelectronic.
Is the ionization energy of alkali metals larger or smaller than the alkaline earth metals in the same period?
It is about first ionization energy. It is less than alkaline earth metals.
What is ratio of total kinetic energies of eight grams of both O2 and H2 at same temperature?
The ratio of the total kinetic energies of eight grams of both oxygen and hydrogen at the same temperature is 1:2 respectively.
Can ionization energies determine an element group?
Yes, ionization energies can be used to determine the group of an element on the periodic table. Elements in the same group have similar trends in ionization energy, with a general decrease moving down a group due to the increase in atomic size. This pattern allows us to predict an element's group based on its ionization energy values.
Which electrons in the first period have higher ionization energies?
The elements of the first period are hydrogen and helium. The trend for ionization energy is to increase left to right across the same period, so helium's ionization energy is higher. Which makes sense, because helium has a full 1s-level, meaning it doesn't need to react. Hydrogen, on the other hand, is very reactive, which is why we stick it in group 1.
Is the relationship between reactivity of metals and ionization energy a direct or inverse relationship?
The relationship between the reactivity of metals and ionization energy is generally an inverse relationship. As ionization energy decreases, it becomes easier for a metal to lose electrons and form positive ions, which increases its reactivity. Therefore, more reactive metals tend to have lower ionization energies. This trend is particularly evident when comparing metals within the same group of the periodic table.
What is isoelectronic with xenon?
Krypton, radon, and xenon cation are all isoelectronic with xenon because they have the same number of electrons.
Are HID and xenon the same?
No, they are not.
