Question | Answer |
---|---|
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) |
