The following image shows NaCl in Lewis Dot Formation.
Na positive, no dots; Cl negative in brackets, 8 dots.
Describe Polar versus non-polar covalent bonds.
Unequally versus equally shared valence electrons due to each elements electronegativity.
Cl2 would be non-polar, while HCl would be polar.
Lithium and Oxygen form a compound. This is how many lithium and oxygen molecules would be required to result in a stable compound due to the octet rule.
What are two lithium and one oxygen, to form Li2O AKA Lithium Oxide.
Neon has a lower electron affinity than other elements for this reason.
What is it has a full outer shell of electrons? (Octet Rule)
The following is the only non-metal in the alkali metal group.
What is hydrogen?
Atomic radius increases when you move in this direction on the periodic table AND Electronegativity increases as you move in this direction on the periodic table.
What is down AND left to right
Francium has the greatest atomic radius (highest period and fewer protons than other period 7 elements) AND Flourine has the greatest electronegativity (best hugger)
