Question

question 14
once we know the number of valence electrons, the atoms are arrange around a central atom - generally the least______ atom of the molecule.
massive
hyperpositive
electronegative
ionic

question 15
1 pts
each atom of a molecule is connected by at least one______ comprised of a pair of electrons.
ionic bond
coordinate ionic bond
hydrogen bond
covalent bond

Explanation:

For Question 14: In molecular - structure determination, atoms are arranged around the least electronegative central atom. Electronegativity determines an atom's ability to attract electrons. For Question 15: A covalent bond is formed when atoms share a pair of electrons. Ionic bonds involve electron transfer, coordinate - ionic bonds are a special type of bonding, and hydrogen bonds are intermolecular forces.

Answer:

Question 14: C. electronegative
Question 15: D. covalent bond
