Loss of a valence electron from sodium gives it same electron configuration as _
Neon
Sodium before Na(g) 1s22s22p63s1
1s22s22p6 Na+
Species with same number of electrons are described as _
Isoelectronic
Older unit for joule is
Calorie
Energy released when _ captures an electron
Chlorine
Energy change for an exothermic process has a _ sigh
Negative
Na in NaCl experiences _
Ionization energy
Cl in NaCl experiences
Electron affinity
We can use IE of sodium and EA of Cl to calculate _
Energy change for reaction
When we add IE for Na and EA for Cl, conclusion is _
Endothermic
Energy liberated by adding electron to chlorine is insufficient to _
Override energy required to remove electron from sodium
However, lattice energy (electrostatic attraction) makes overall process of NaCl _
Exothermic
Forces between charged particles are called electrostatic or _
Coulombic
Ionic bonds very common in inorganic compounds but rare in _
Organic
Ionization energy of carbon is too large and _ too small for ionic bond
Electron affinity
