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.

∙ 12y agoas you proceed down a group, the outermost electrons in ions are higher in energy levels. therefore just as atomic radius increases as you move down a group, usually the ionic radius increases as well. these trends hold for both positive and negative ions.
Ionization energy increases as you move across a period and decreases as you move down a group.

∙ 13y agoThe trend in effective nuclear charge accounts for the increase in ionization energy across a period. The trend in principal quantum numbers accounts for the decrease in ionization energy down a group.

∙ 12y agoIonization energy increases from left to right across a period. This is because from left to right across a period, electrons are being added to the same energy level. The closer the valence shell gets to being filled, the harder it is to remove an electron. Ionization energy decreases from top to bottom down a group. This is because the outermost energy level being filled with electrons increases down a group. The higher the energy level, the farther away the valence shell is from the positively charged nucleus, so the valence electrons are not being held as tightly, and it becomes easier to remove an electron from the valence shell.

∙ 9y agoIonization energy increases as elements move to the right of the Periodic Table and up the periodic table. Na is weaker in energy level than Ne.

Does chlorine have a high electron affinity or a low ionization energy?
It has High electron affinity.
The energy released during the ionization of a non-metal is called the?
ionization energy
What information about an element is provided on the modern periodic table?
Atomic mass Atomic number Elemental symbol
What part of the atom is able to be lost or gained?
the energy is require to remove an electron from an atom (ionization energy) but when electron is absorbed in an atom energy is released (electron affinity) however 2nd electron affinity is endothermic ,energy is require.
Which has the larger sixth ionization energy Se or Br?
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, etc. Ionization energy generally increases for every electron that is removed, and increases from left to right in the periodic table or if moving up the periods. In this case, from the periodic table (or according to Mastering Chemistry) Bromine (Br) has a larger sixth ionization energy than Selenium (Se).
What periodic treds exist for ionization energy?
Ionization energy increases to the right and up on the periodic table. Ionization energy is the energy required to remove an electron. It can be conceptualized as the opposite of electron affinity, though this is not precisely true.
Does chlorine have a high electron affinity or a low ionization energy?
It has High electron affinity.
Are there any trends to the periodic table?
Atomic Radii,Ionic Radii, First Ionization Energy,Second and Higher Ionization Energies, Electron Affinity.
The energy released during the ionization of a non-metal is called the?
ionization energy
How do you create an electron affinity reactor?
To create an electron affinity reactor you will have to use the second ionization energy.
In the periodic table which one is the smallest?
radius: He ionic radius : Mn7+ electronegativity : Fr electron affinity : Fr ionization energy: H
What are three periodic trends you encounter in your life?
Seasons: The changing of seasons, like summer, fall, winter, and spring, is a recurring pattern we encounter each year. Lunar cycles: The phases of the moon, such as full moon and new moon, occur in a regular cycle. Paychecks: For many people, receiving a paycheck on a bi-weekly or monthly basis is a periodic trend that impacts their financial planning.
What do you call the energy involved when an atom loses an electron?
The amount of energy required to remove an electron form an at is the ionization energy.
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.
What happens as we move down columns on the periodic table?
As you move down a column (group) in the periodic table, the electronegativity decreases, the ionization energy decreases, the electron affinity decreases, and the atomic radius increases.
Does Sr have a high electron affinity or a low electron affinity?
Strontium, Sr, doesn't accept electrons, so it has low electron affinity. Sr will liberate electrons, so it has low ionization energy.
What information about an element is provided on the modern periodic table?
Atomic mass Atomic number Elemental symbol
