Explanation:

Step1: Analyze first atom diagram

The nucleus shows 8 protons. Count electrons: inner shell=2, outer shell=8 → total 10 electrons.

Step2: Calculate net charge

Net charge = (number of protons) - (number of electrons) = $8 - 10 = -2$

Step3: Classify ion and write notation

Charge is negative, so it's an anion. The element with 8 protons is oxygen (O). Ion notation: $\text{O}^{2-}$

Step4: Analyze second atom diagram

Nucleus shows 3 protons. Count electrons: 2 electrons.

Step5: Calculate net charge

Net charge = $3 - 2 = +1$

Step6: Classify ion and write notation

Charge is positive, so it's a cation. The element with 3 protons is lithium (Li). Ion notation: $\text{Li}^{+}$

Step7: Correct earlier fill-in errors

• Atom losing electrons: positive (not negative)
• Atom gaining electrons: negative (not positive)
• Atom with 12 electrons, 10 protons: net charge = $10 - 12 = -2$, it's an anion; element is neon is wrong, element is sodium? No, protons=10 is neon? No, protons define element: 10 protons = neon, but net charge -2, so anion $\text{Ne}^{2-}$? Wait no, 10 protons is neon, yes. Charge is -2, so anion.

Answer:

Matching Section (corrected):

1. Electric charge → C. Property of matter responsible for electrical events; it has two forms, positive and negative.
2. Static electricity → E. A buildup of charge on an object.
3. Electrical force → B. The pushes and pulls that electric charges exert on each other.
4. Coulomb → A. A unit in measuring the amount of charge.
5. Electrically neutral → D. An object that has equal amounts of positive and negative charges.

Fill-in Blanks (corrected):

• An atom that loses electrons becomes positive
• An atom that gains electrons becomes negative

Atom with 12 electrons, 10 protons:

• Charge: $-2$ (negative)
• Element: Neon (Ne, since protons=10)
• Ion type: Anion

First Bohr Diagram (8 protons):

• Protons: 8
• Electrons: 10
• Net Charge: $-2$
• Neutral or Ion? Ion (Anion)
• Ion Notation: $\text{O}^{2-}$

Second Bohr Diagram (3 protons):

• Protons: 3
• Electrons: 2
• Net Charge: $+1$
• Neutral or Ion? Ion (Cation)
• Ion Notation: $\text{Li}^{+}$
