Molecular equation:
<span>Na2CO3 (aq) + CaCl2 (aq) → CaCO3 (s) + 2 NaCl (aq) </span>
<span>Ionic equation: </span>
<span>2 Na⁺ (aq) + CO3²⁻ (aq) + Ca²⁺ (aq) + 2 Cl⁻ (aq) → CaCO3 (s) + 2 Na⁺ (aq) + 2 Cl⁻ (aq) </span>
<span>Net ionic equation: </span>
<span>CO3²⁻ (aq) + Ca²⁺ (aq) → CaCO3 (s)</span>
Since neon has 8 valence electrons, a full octet makes neon stable. It is also a noble gas. Then, you do the configuration...
1s2 2s2 2p6
2s holds 2 valence electrons while 2p has 6 that equals a full octet.
