1. choose the best answers.

chemical nomenclature is a(n)_____used to name compounds.
oxidation number
system
ratio

1. choose the best answer.

small ions likely form a_____.
double bond
strong bond
weak bond
single bond

Explanation:

Question 1

Chemical nomenclature is a set of rules (a system) for naming chemical compounds. Oxidation number is about electron transfer, and ratio is a proportion, neither fit for naming compounds. So "system" is correct.

Small ions have a high charge density, which leads to stronger electrostatic interactions when forming bonds, so they likely form a strong bond. Double/single bonds relate to bond type (not ion size), and weak bond is opposite to the effect of small ion's charge density.

Answer:

B. system
