Which of the following comes first in the name of an ionic compound? (1 point)
The number of ions present
The positively charged ion
the neutral ion
the negatively charged ion
The positively charged ion comes first in the name of an ionic compound.
In the name of an ionic compound, the positively charged ion comes first.
To determine which of the options comes first in the name of an ionic compound, you need to understand the basic naming rules for such compounds.
Ionic compounds consist of positively charged ions (known as cations) and negatively charged ions (known as anions). The name of an ionic compound is derived from the combination of the names of these ions. The general rule is that the name of the cation always comes first, followed by the name of the anion.
Considering the options provided:
1. The number of ions present: The number of ions present does not determine the order of naming in an ionic compound. It is irrelevant to the naming convention.
2. The positively charged ion: This is the correct answer. The name of the positively charged cation comes first, followed by the name of the negatively charged anion. For example, in the compound NaCl, "Na" represents the sodium cation, which is the positively charged ion.
3. The neutral ion: The term "neutral ion" is not a commonly used phrase in chemistry. Ions are either positively or negatively charged. Therefore, this option is not applicable.
4. The negatively charged ion: This option is incorrect. The name of the negatively charged anion comes after the name of the positively charged cation.
In summary, the positively charged ion comes first in the name of an ionic compound.
