In general, the larger the atom the lower the first ionization energy at the right hand side of the Periodic Table. Take Lithium and Francium as examples. With Francium, the outer electron is much further away from the attractive power of the nucleus and is shielded by all the other electrons. The attraction is lower and thus it is easier to remove the electron making the first ionization energy lower. Incidentally, it makes it more reactive.

Which atom has the smaller ionization energy B or N?
Boron has a larger ionization energy than nitrogen. Nitrogen has a smaller atomic size compared to boron, resulting in stronger nuclear attraction for its electrons, making it more difficult to remove an electron from a nitrogen atom than from a boron atom.
What is the relationship between elements and the periodic table and ionisation energy?
Ionisation energy is the energy required to remove an electron from an atom. Elements in the periodic table exhibit trends in ionisation energy based on their atomic structure. Generally, ionisation energy increases across a period and decreases down a group in the periodic table.
Does helium have the largest first ionization energy of all the elements?
No, helium does not have the largest first ionization energy of all the elements. Helium actually has the highest first ionization energy of any element, due to its small atomic size and stable electron configuration.
What noble gas has lowest ionization energy?
well... since theionization energy is bigger at the top right of the periodic table, then Helium(He) is the element which has the highest ionization energy. Whereas Francium(Fr) has the lowest ionization energy, because it's located at the most bottom left of the periodic table.
How does the size of the atom affect the energy needed to remove an electron?
The energy needed to remove an electron, known as ionization energy, decreases as the size of the atom increases. Larger atoms have electrons that are farther from the nucleus, reducing the attractive force holding electrons, making it easier to remove an electron.
Why is it easier to lose electrons from a cesium atom than from a lithium atom?
It is easier to lose electrons from a cesium atom than from a lithium atom because cesium has a larger atomic size and low effective nuclear charge, making it easier for outermost electrons to be removed. In contrast, lithium has a smaller atomic size and higher effective nuclear charge, resulting in stronger attraction to its electrons and making them harder to remove.
What is the lowest first ionization energy?
The lowest first ionization energy is found in francium, the element with the highest atomic number. Francium has the lowest ionization energy because the outermost electron is held the weakest due to the large atomic size and shielding effects.
Which atom has the smaller ionization energy B or N?
Boron has a larger ionization energy than nitrogen. Nitrogen has a smaller atomic size compared to boron, resulting in stronger nuclear attraction for its electrons, making it more difficult to remove an electron from a nitrogen atom than from a boron atom.
Is magnesium's ionization energy higher or lower than chlorine?
ionization energies of mg is less than chlorine because chlorine requires only one electron to complete its octet so it will not prefer to loose its electron morover its electronegativity is also higher and it is of smaller size than mg so electtron removal is difficult
Why does oxygen have a higher ionization energy than sulfur?
Oxygen has a higher ionization energy than sulfur due to its smaller atomic size and stronger nuclear charge. The electrons in the outer energy level are held more tightly in oxygen compared to sulfur, requiring more energy to remove an electron from an oxygen atom.
Why does bigger size atom have low ionization energy?
It is " bigger " because it has more electrons in orbit around it. So, to keep things simple and away from such concepts as shielding, we know that the farther electrons are from the nucleus the looser they are held and to ionize this element is easier, thus lower ionization energy needed.
Why does helium have a higher ionization than argon?
Helium has a higher ionization energy than argon because helium has a smaller atomic size and a full valence shell, making it more stable and requiring more energy to remove an electron. Argon, being a larger atom with more electron shielding, has a lower ionization energy as the electrons are further away from the nucleus and experience less attraction.
Does carbon or oxygen have a higher ionization energy?
Oxygen has a higher ionization energy than carbon. This is because oxygen has a greater nuclear charge and a smaller atomic size compared to carbon, making it more difficult to remove an electron from an oxygen atom due to stronger attraction between the electrons and the nucleus.
What has the largest ionization energy between oxygen carbon boron and nitrogen?
Nitrogen has the largest ionization energy among oxygen, carbon, boron, and nitrogen. This is because nitrogen has a smaller atomic size and higher effective nuclear charge compared to the other elements, making it harder to remove an electron from a nitrogen atom.
Which element P or Ca has the highest first ionization energy?
The element P (Phosphorus) has a higher first ionization energy than Ca (Calcium). This is because Phosphorus has a smaller atomic size and higher effective nuclear charge compared to Calcium, making it harder to remove an electron from a Phosphorus atom than a Calcium atom.
Which atom lithium or cesium needs more energy to become an ion?
Cesium needs more energy to become an ion than lithium because cesium has a higher ionization energy due to its larger atomic size and greater distance of valence electrons from the nucleus. This makes it more difficult to remove electrons from cesium compared to lithium.
In same group of elements ionization energy tends to decrease with increasing atomic number decreasing size of atom increasing forces of attraction or outer electrons being farther from the nucleus?
