3. ions
atoms are the fundamental building blocks of matter, and in their natural state, they are electrically neutral, having an equal number of protons (positively charged) and electrons (negatively charged). however, atoms can gain or lose electrons, leading to the formation of charged particles called ions. this process occurs to achieve a more stable full outer electron shell.

there are two main types of ions:
- cations: these are positively charged ions formed when an atom loses one or more electrons. cations are typically formed by metals.
- symbols and examples:
- sodium atom (na) loses one electron to become a sodium ion: $\text{na}^+$
- calcium atom (ca) loses two electrons to become a calcium ion: $\text{ca}^{2+}$
- aluminum atom (al) loses three electrons to become an aluminum ion: $\text{al}^{3+}$
- anions: these are negatively charged ions formed when an atom gains one or more electrons. anions are typically formed by non-metals.
- symbols and examples:
- chlorine atom (cl) gains one electron to become a chloride ion: $\text{cl}^-$
- oxygen atom (o) gains two electrons to become an oxide ion: $\text{o}^{2-}$
- nitrogen atom (n) gains three electrons to become a nitride ion: $\text{n}^{3-}$

ions are crucial in chemistry as they are essential components of solutions, contributing to conductivity and various chemical reactions.

naming ions
- for cations, the name of the atom remains the same, followed by the word ion. for example, a sodium atom (na) that loses an electron becomes a sodium ion.
- if a metal can form multiple ions with different charges, a roman numeral in parentheses is used to indicate the charge (e.g., iron(ii) ion for $\text{fe}^{2+}$).

Sugar syrup is made by dissolving sugar in water. Therefore, sugar is the solute and water is the solvent. ## Identify components of coffee Coffee is prepared by brewing coffee grounds in water. The soluble compounds extracted from the coffee beans act as the solute, while water acts as the solvent. ## Identify components of copper sulfate solution An aqueous copper sulfate solution is prepared by dissolving copper sulfate in water. Therefore, copper sulfate is the solute and water is the solvent. ## Question 2 2. Solution: sugar syrup * Solute: sugar * Solvent: water ## Question 3 3.
