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.
What else can I help you with?
What elements have the largest first ionization energy?
Elements in the top right corner of the periodic table tend to have the largest first ionization energies. This includes elements such as helium, neon, and fluorine. They have a strong attraction for their valence electrons due to their small atomic size and high effective nuclear charge.
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?
Noble gases have the highest first ionization energies because they have a full valence shell, making it difficult to remove an electron. Within a period, ionization energy generally increases from left to right due to increasing nuclear charge.
What is the trend in period 2 ionization energy across the elements?
The trend in period 2 ionization energy across the elements increases from left to right.
What is the trend in ionization energy of period 3 elements on the periodic table?
The trend in ionization energy of period 3 elements on the periodic table generally increases from left to right.
Has largerst ionization energy in its period?
The element with the largest ionization energy in its period is typically found in the top right corner of the periodic table. This is because elements in this region have the highest effective nuclear charge, making it harder to remove an electron. In general, elements like helium, neon, and fluorine tend to have the highest ionization energies in their respective periods.

Does arsenic have the highest ionization energy?
No, arsenic does not have the highest ionization energy. Ionization energy generally increases as you move across a period in the periodic table from left to right. In the case of arsenic, it is found in the 3rd period, so elements to the right of it, such as bromine, have higher ionization energies.
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.
Elements that have the highest first ionization energy?
Noble gases have the highest first ionization energies because they have a full valence shell, making it difficult to remove an electron. Within a period, ionization energy generally increases from left to right due to increasing nuclear charge.
What would you predict about the ionization energies of these elements?
Ionization energy generally increases across a period from left to right due to increasing nuclear charge, which holds electrons more tightly. Conversely, ionization energy decreases down a group as additional electron shells are added, increasing the distance between the nucleus and the outermost electrons, making them easier to remove. Therefore, elements located further to the right in a period and higher up in a group tend to have higher ionization energies compared to those further left or lower down.
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?
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.
Atoms with large ionization energy values are what?
Atoms with large ionization energy values are typically nonmetals, particularly those found in the upper right corner of the periodic table, such as noble gases and halogens. These atoms hold their electrons tightly, making it difficult to remove an electron and requiring a significant amount of energy to do so. As a result, elements with high ionization energies tend to be less reactive and form fewer cations. Their strong attraction to their electrons contributes to their stability and unique chemical properties.
What is the trend in period 2 ionization energy across the elements?
The trend in period 2 ionization energy across the elements increases from left to right.
