Why do elements in the top right corner have high ionization energies?

∙ 10y ago
Ionization energy is the energy required to remove an electron from an atom. In the case of hydrogen, its one and only electron is very close to the nucleus, because it is in the first energy level (that electron's ground state.) So, the attraction between the nucleus (positive) and that electron (negative) is quite strong due to their closeness. As you move down group 1, the electrons get farther and farther away from the nucleus, and the attraction, predictably, decreases. This means lower ionization energy required the lower you go on the group.

∙ 10y agoThe elements in this part of the Periodic Table want to gain electrons to get to a noble gas configuration - not lose them. To lose electrons is very energetically unfavorable (high ionization energies).

∙ 10y agoThey have a full outer shell, the most stable way an atom can be. Ionization
energy refers to the energy required to remove an electron from that atom. It is very unfavourable to lose an electron when you have a balanced outer shell.

*Their atomic radius is small
*They have fewer electron shells to shield the protons from the electrons

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.
Elements that have the highest first ionization energy?
Helium (He) has the highest first ionization energy. Ionization energy increase as you go across the periodic table from left to right
What accounts for the general trend in the first ionuization energy of the elements within a period?
As you go from right to left in a period in the periodic table the ionization energy increases. While going from top to bottom in a group in the periodic table the ionization energy decreases .
What is the general trend of ionization energy as you go across the periodic table?
Across a period, first ionization energy increases. However, when going down a group, first ionization energy generally decreases. As you go down a group, atoms hove more total electrons so they don't really care that much about their outermost ones.
What trend is seen on the periodic table?
"Electronegativity"

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.
Elements that have the highest first ionization energy?
Helium (He) has the highest first ionization energy. Ionization energy increase as you go across the periodic table from left to right
What type of elements tend to have low ionization energies?
The elements in the lower right part of the Periodic Table. Cs, Fr, Ra, Ba etc.
Ionization energies tend to do what from left to right across a period?
increase from left to right across a period.
Which elements has the highest ionization energy?
Helium (He) has the highest ionization energy, then Neon (Ne) Ionization energy increases as you go across a period from left to right. Ionization energy decreases as you go down a group. Therefore, elements in the upper right of the periodic table have the highest ionization energy.
Which electrons in the first period have higher ionization energies?
In the first period, the ionization energy increases from left to right across the period. Therefore, the electrons on the right side of the first period (e.g., helium, neon) have higher ionization energies compared to the electrons on the left side (e.g., hydrogen, lithium).
Which atom or ion in each pair has the larger ionization energy Cl or P?
Chlorine, Cl. Elements with the most ionization energy are located at the top right corner of the periodic table. As you travel down a period the ionization energy increases, whereas travelling down a group the ionization energy decreases.
Elements belong in upper ionization energy?
All of the elements on the top half of the periodic table belong in upperionizationenergy because the trend is top to bottom. Top being lowest and getting bigger as it goes down.------------------------------------------------------* In a group: the ionization energy decrease from the lighter elements to heavier elements.* In a period: the ionization energy increase from the left elements to the elements of the right.* When the atomic radius decrease the ionization energy increase.
What element in period 3 has the highest second ionization energy?
Fluorine because it is the furthest right on the periodic table. Do no include noble gases in energies.
What is the differences between first and second ionization energy?
The first ionization energy is the energy that is required in order to remove the first electron from an atom in the GAS phase, the second ionization energy is the energy required to remove the second electron from an atom in the GAS phase. Ionization energy will generally increase for every electron that is removed and increases from left to right in the periodic table and moving up the periods.
What happens to the first ionization energy of the elements as a period is crossed?
Moving from left to right across a period, the first ionization energy increases because it becomes increasingly difficult to remove an electron.
What are the general properties of the elements in the group on the right side of the periodic table?
The elements present at right side groups of the periodic table are non-metals. They have high electron affinity and ionization energy.
