What else can I help you with?
Does the first ionization energy increase or decrease when you go down a group?
it increases
What is the Trend in first ionization energy across a period?
As one proceeds down the group 7A elements, the first ionization energy decreases. this means that the outermost electron is more readily removed as we go down a group.
Describe the trends in first ionization energy within groups and across periods in the periodic table Provide examples?
Within a group, first ionization energy generally decreases as you move down the group due to increasing atomic size and shielding effects. Across a period, first ionization energy generally increases due to increasing nuclear charge and effective nuclear charge. For example, within Group 2 (alkaline earth metals), the first ionization energy decreases as you move down the group from Be to Ra. Across Period 3, the first ionization energy increases from Na to Cl.
How does the first ionization energy change going down and across the periodic table?
As you move down a group on the periodic table, the first ionization energy generally decreases due to the increasing atomic size and shielding effect of inner electrons. Across a period, the first ionization energy generally increases because the effective nuclear charge increases, making it harder to remove an electron.
Is it ionization energy is a periodic property?
Ionization energy generally increases across a period as a result of a higher nuclear charge, however there are some exceptions such as Boron which has a lower ionization energy than Beryllium (because it is in a P orbital), and Oxygen which has a lower ionization energy than nitrogen (Because ionization decreases the electron electron repulsion in its orbitals).
Does the first ionization energy increase or decrease when you go down a group?
it increases
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.
How does ionization energy of elements in the same period change?
Ionization energy increases as you go across a period, but as you go down a group it decreases.
What is the Trend in first ionization energy across a period?
As one proceeds down the group 7A elements, the first ionization energy decreases. this means that the outermost electron is more readily removed as we go down a group.
How do elements change going down the periodic table?
Down a group, the atomic number generally increases, size increases, ionization energy decreases, reactivity increases.

What is the periodic trend for ionization energy and electron affinity?
Ionization energy increases from left to right across a period, and decreases down a group.
In ionization energy how does the property varies within a group?
The ionization energy decrease moving down in a group.
What trend in ionization energy occurs going down on the periodic table and why?
when you go down a group you get more shells and in those shell are electrons the further away the electrons are from the protons and neutrons the less energy you need to pull of the electrons.
Why ionization energy decreases down the group and increases along a period?
Going down a group, the number of valence electrons remains the same, but these electrons get farther and farther away from the nucleus. Thus, they are not as tightly held and the ionization energy decreases. Moving from left to right along a period, the electrons are the same distance from the nucleus, but the number of protons are increasing in the nucleus, thus holding those electrons more tightly. Thus, the ionization energy increases.
