Angela was instructed on a test to make an analogy, or comparison, for polymers. she writes four examples of how polymers are like pearl necklaces. she has many parts to this analogy that make sense, but one part of her analogy does not fit. which is the most likely error in her analogy? the pearls are like monomers. the thread that connects the pearls is like an ionic bond. the entire necklace is like a polymer, or macromolecule. stringing the beads onto the thread is like polymerization.

The thread that connects the pearls is like an ionic bond.

Explanation:

Polymers are macromolecules conformed by several monomers (precisely how several pearls connected together form one pearl necklace). These monomers are bonded together through a process known as polymerization (just like stringing the beads together in the necklace).

However, the bonds between the monomers are not ionic, they are covalent. Polymers are usually made from organic compounds, and as such they have C-C, C-H, C-N and C-O bonds, which are covalent.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
