Group vertical columns of the periodic table
Period horizontal rows of the periodic table
First Ionization Energy The energy required to remove one mole of electrons from a mole of atoms or ions in the gaseous phase
X(g) --> X+(g) + e- First Ionization Energy
Electron affinity is the energy released when 1 mol of electrons is attached to 1 mole of neutral atoms or molecules in the gas phase
X(g) + e- --> X-(g) Electron affinity
Electronegativity is a measure of the ability of an atom to attract bonded electron pairs to itself when in a covalent bond
Na(s) + H2O(l) → NaOH(aq) + H2(g)
2Na(s) + Cl2(g) → 2NaCl(s)
Na2O(s) + H2O(l) --> 2NaOH(aq)
MgO(s) + H2O(l) --> Mg(OH)2(aq)
P4O10(s) + 6H2O(l) --> 4H3PO4(aq)
SO2(g) + H2O(l) --> H2SO3(aq)
SO3(l) + H2O(l) --> H2SO4(aq)
