The correlation between ionization energy of sodium atom and
Concept introduction:
Ionization energy:
In a gaseous state isolated neutral atom, the amount of energy required to eject an electron from outermost shell is known as ionization energy. Ionization energy increases from left to right across periods due to increase of effective nuclear charge. Ionization energy decreases down the group due to addition of electrons enters into new orbital which is far from nucleus.
Electron affinity:
In a gaseous state isolated neutral atom, energy released when an electron is introduced in outermost shell is known as electron affinity. Greater the negative value of electron affinity, the atom has more tendency to accept an electron.

- Rank the following ions in order of increasing first ionization energy: O2–, Mg2+, F–, Na+.arrow_forwardThe ionization energy of an alkali metal is reflected in its reaction with water, where a bigger explosion indicates an easier reaction. In general, if X is an alkali metal, the reaction with water is: X (s) + H2O (l) = XOH (aq) + H2 (g). How does the reaction relate to the ionization of X? Write the reaction for X in the boxes below. This reaction does not need to be balanced. Any other species and the state of the reactants and products can be ignored. Include the formal charge in the superscript box. If there is no formal charge, write "0".arrow_forwardWrite the electron-dot symbol for any element X in group 3A.arrow_forward
