(a) Which is expected to have the shortest ionic bonds?
(b) Which is expected to have the highest lattice energy?
(c) Which is expected to have the lowest melting point?
ii.
Answer true or false.
(a) A covalent bond is formed between two atoms whose difference in electronegativity is less
than 1.9.
(b) If the difference in electronegativity between two atoms is zero (they have identical
electronegativities), then the two atoms will not form a covalent bond.
(c) A covalent bond formed by sharing two electrons is called a double bond.
(d) In the hydrogen molecule (H2), the shared pair of electrons completes the valence shell of
each hydrogen.
(e) In the molecule CH4, each hydrogen has an electron configuration like that of helium, and
carbon has an electron configuration like that of neon.
(f) In a polar covalent bond, the more electronegative atom has a partial negative charge (8-)
and the less electronegative atom has a partial positive charge (&+).
(g) These bonds are arranged in order of increasing polarity C-H
