15 Questions
What is ionization energy?
The minimum energy required to remove the outermost electron in an atom
Why are valence electrons more easily removed compared to inner electrons?
They are furthest from the nucleus and are influenced the least by the positively charged nucleus
As more electrons are removed from an atom, what happens to the ionization energy?
It increases as the remaining electrons experience a stronger attraction to the nucleus
How is ionization energy measured?
Kilojoules per mole
What does the formula for ionization energy represent?
The energy required to remove an electron from an atom
As an ion becomes more positively charged, what happens to its hold on remaining electrons?
It becomes tighter
What happens to the ionization energy as electrons are continually removed from an ion?
It increases as the ion becomes more positively charged
What is ionization energy?
The minimum energy required to remove a valence electron from an atom
Why does ionization energy increase from left to right within a period on the periodic table?
More positively charged protons in the nucleus increase the influence on the negatively charged electrons
Why does ionization energy decrease moving down a group on the periodic table?
Increasing the number of electron orbitals weakens the positive force felt by the outermost electron from the nucleus
What is the trend of ionization energy when moving from the bottom left corner of the periodic table to the top right corner?
Increases
What is the relationship between the number of electron shells and ionization energy?
Ionization energy increases as the number of electron shells decreases
What is the main factor affecting ionization energy?
The number of electron orbits around the nuclei and the number of protons in the nuclei
What happens to ionization energy as the atomic radius increases?
Ionization energy decreases
Why does the nucleus of an atom with more protons require more energy to strip the outermost electrons?
The nucleus has a stronger positively charged force that pulls the electron shells in tighter around the nucleus
