how are electron affinity and ionization energy related?
160086
Ionization energy is the energy required to remove an electron away from an atom, which can be written as IE. ... Electron affinity, on the other hand, is the energy released when an electron is added to the atom. On the periodic table, electron affinity usually decreases down a group, and increases across a period.

Ionization energy is the energy required to remove an electron from a neutral atom in its gaseous phase. Conceptually, ionization energy is the opposite of electronegativity. ... Generally, elements on the right side of the periodic table have a higher ionization energy because their valence shell is nearly filled.

Ionization Energy Trends Conceptually, ionization energy is the opposite of electronegativity. The lower this energy is, the more readily the atom becomes a cation. Therefore, the higher this energy is, the more unlikely it is the atom becomes a cation.

The (1st) ionization energy is the energy associated with the formation of 1 mole of negative ions from 1 mole (gaseous) atoms, and 1 mol of (gaseous) electrons. The ionization potential is this energy measured in electron volts.

Generally, the higher and atom's electron affinity the higher its electronegativity. All three have the same trend of increasing as you move up and to the right on the periodic table.

The energy amount needed to remove an electron from an atom. Ionization energy, IE. This energy is measure when an element is in its BLANK state. ... The more BLANK the electrons are from the nucleus the BLANK the electrons are attracted by the protons resulting in less amount of energy needed to remove the electron.

2nd Electron Affinity is always endothermic since an additional electron is added to a negative ion. Energy is absorbed to overcome inter-electronic repulsion between two negatively charged species.

And 2nd ionization energy is higher than 1st ionization energy, 3rd is higher than 2nd, and so forth. (I just wanted to clarify from an above answer: 2nd i.e. is not the energy it takes to remove 2 electrons together; it's the energy it takes to remove 1 electron from an atom that has already lost 1 electron before.)

When excitation occurs the orbital electron is promoted to a higher energy level within the atom, but when ionisation occurs the electron receives enough energy to completely leave the atom. (b) An atom can also become excited by the absorption of photons.

1 Answer. The first ionization energy is the energy it takes to remove an electron from a neutral atom. The second ionization energy is the energy it takes to remove an electron from a 1+ ion. ... The third ionization energy is the energy it takes to remove an electron from a 2+ ion.

Ionization enthalpy is the minimum amount of energy which is required to knock out the most loosely bound electron from an isolated gaseous atom so as to convert it into a gaseous cation. whereas ionization energy is the amount of energy required to remove the electron from ground state to the infinity.

Answer and Explanation: Ionization energy is endothermic because it requires an energy input to occur. Ionization is the process of removing negatively charged electrons from...

Ionization energy: the energy required to remove an electron from a neutral atom. ... Electronegativity: the ability of an atom in a molecule to draw bonding electrons to itself.

Electron binding energy, more commonly known as ionization energy, is a measure of the energy required to free an electron from its atomic orbital. ... The atomic binding energy of the atom is the energy required to disassemble an atom into free electrons and a nucleus.

Correct Answer: (3) Electronegativity and first ionization energy both increase. Reason: Electronegativity and ionization energy are dependent on effective nuclear charge and size of atom.

Ionization energy is the energy required to remove the most loosely held electron from a gaseous atom or ion.

Ionization energy is the energy required to remove an electron from the atom. (First ionization energy is the energy needed to remove the most loosely held electron from the atom). ... Electronegativity is the tendency of the atoms of an element to attract electrons when they are chemically combined with another element.
