Question

drag the oval over the words that complete the sentences below:

ions, which are charged particles, can be either positive or negative. positive ions, known as cations / anions have lost / gained electrons and are represented in this activity by pieces that have indents.

each indent represents a respective quantity of electrons. additionally, negative ions, known as cations / anions have lost / gained electrons and are represented by pieces that have points. the number of points represents a respective quantity of electrons.

Explanation:

🆕 New Concept Discovered: Ion Formation and Naming
Understanding how atoms gain or lose electrons to form charged ions.

Step 1: Identify positive ions

Positive ions are formed when a neutral atom loses negatively charged electrons, leaving it with a net positive charge.

• Name: Positive ions are called cations (a helpful way to remember this is that the "t" in cation looks like a plus sign \(+\)).
• Electron change: Because electrons have a negative charge, losing them makes the atom positive. Therefore, they have lost electrons.

Step 2: Identify negative ions

Negative ions are formed when a neutral atom gains negatively charged electrons, giving it a net negative charge.

• Name: Negative ions are called anions (a helpful way to remember this is a negative ion = anion).
• Electron change: Because electrons have a negative charge, adding them makes the atom negative. Therefore, they have gained electrons.
