There is an attraction of the nucleus for electrons. This attractive force must be overcome to remove an electron. The energy to overcome this attraction and remove an electron from the atom is 'ionization energy'.

What best defines the ionization energy of an element?
The amount of energy needed to remove the outermost electron.
What is einsteinium's ionization energy?
The ionization energy (first) of einsteinium is 619 kJ/mol.
Do the elements form anion have high or loe ionization energy?
low ionization energy
What is Argon Ionization Energy?
15.759
First ionisation energy equation?
The equation for first ionization energy is the equation for the energy required to remove an electron from one mole of gaseous atoms to produce a mole of gaseous ions. It is as follows: X(g) ---> X^+1(g) + e^-1.
What is the energy needed for ionization called?
ionization energy
What is parent ionization energy?
It is the energy that is needed for ionization to happen. The parent ion is the ion before ionization, after it is known as the daughter ion
What is the energy needed to remove electrons from an atom called?
ionization potential energy. but remember the atom must be neutral .
What is ionization energy and how does it relate to the periodic table?
The ionization energy is the energy needed to extract an electron from an atom.The value of the ionization energy increase from left to right in a period of the periodic table and decrease in a group from the above to down.
How is the ionization energy of an element defined?
Ionization energy is the energy needed to remove 1 mole of loosely bonded electrons from one mole of atoms or ions.
The amount of energy that is needed to remove the most loosley held electron is referred to as the what?
You are referring to the ionization enthalpy. The first ionization energy of sodium is the energy for the process Na(g) --> Na+(g) + e-(g).
Why is the ionistaion energy of magnesium higher than that of sodium?
because ionization energy increases from left to right on the periodic table. Ionization energy is the amount of energy needed to take an electron away from the atom, or the energy needed to ionize it. Since Sodium is more likely to give up an ion to complete the octet rule, it has a higher ionization energy.
What it ionization energy?
This is the energy needed to extract an electron from an atom in gaseous phase, to form a cation.
What best defines the ionization energy of an element?
The amount of energy needed to remove the outermost electron.
Which of these elements has the highest first ionization energy Si or C?
The ionization energy is the energy needed to extract an electron from an atom; first ionization energy, second, third etc. can be measured. Reactive chemical elements have lower ionization energy.The first ionization energy for silicon is 786,5 kJ/mol.The first ionization energy for carbon is 1 086,5 kJ/mol.
What is the energy needed to remove an electron from a negative ion to form a neutral atom or molecule?
Ionization energy
What is the energy needed for the process of removing electrons and forming charged atoms is called?
The ionization energy of an element.
