10 Questions
What is ionization energy?
The minimum energy needed to remove a valence electron
Why does ionization energy increase across a period?
As the number of electron shells increases
Which element would likely have the highest ionization energy?
Neon (Group 8a)
Why does ionization energy decrease going down a group?
Increase in the number of electron orbitals
Which element would have lower ionization energy, lithium or cesium?
Cesium
What is the definition of ionization energy?
The minimum amount of energy required to remove the outermost electron in the electron cloud of an atom.
Why are valence electrons more easily removed compared to inner electrons?
Valence electrons are more influenced by the atom's nucleus.
Which factor causes it to become increasingly difficult to remove electrons from an atom?
Decreasing positive charge on the nucleus.
How is ionization energy measured?
In kilojoules per mole.
Why does an ion with a higher positive charge have a tighter hold on its remaining electrons?
It gains more protons in its nucleus.
Learn about ionization energy, which is the minimum energy required to remove the outermost electron in an atom. Valence electrons, being the furthest from the nucleus, are the first to be stripped away.
