Question

Accepted Answer

### Question 1: Why do atoms form bonds?
# Brief Explanations:
Atoms form bonds to achieve a stable electron configuration, typically by filling their outer valence shell (octet rule for many). Option A is incorrect as becoming neutral isn't the main drive (atoms are neutral). Option C is wrong (they don't aim to be positive). Option D is incorrect (they don't aim to give many valence electrons, but to stabilize). So the correct reason is to fill the outer valence shell.
# Answer: B. To fill their outer valence shell

### Question 2: Which type of bond is formed from atoms sharing electrons between them?
# Brief Explanations:
Covalent bonds involve sharing electrons. Metallic bonds are electron sea, ionic is transfer, neutral isn't a bond type. So covalent is the answer.
# Answer: A. Covalent

### Question 3: Which type of bond is created from atoms transferring electrons between them?
# Brief Explanations:
Ionic bonds form when electrons are transferred (one atom gives, one takes). Covalent is sharing, metallic is electron sea, neutral isn't a bond. So ionic is correct.
# Answer: G. Ionic (assuming G is Ionic as per options)

### Question 4: Which of the following covalent bonds is the strongest?
# Brief Explanations:
Bond strength: triple > double > single. Triple bond between two nitrogens (N₂ has a triple bond) is stronger than single (H₂), double (O₂), or two single bonds (H₂S). So triple bond is strongest.
# Answer: C. Triple Bond between two Nitrogens

### Question 5: What is the charge of Sulfide ion?
# Brief Explanations:
Sulfide ion is S²⁻, so charge is -2. Option A is +1 (wrong), B +2 (wrong, it's negative), D -1 (wrong, sulfide is -2). So correct is -2.
# Answer: C. -2

### Question 6: How many bonds will neutral Oxygen make?
# Brief Explanations:
Oxygen has 6 valence electrons, needs 2 more. So it forms 2 bonds (to share 2 electrons or accept 2, but in covalent, it shares 2, forming 2 bonds). So 2 bonds.
# Answer: B. 2 bonds

### Question 7: What type of bond will form between Oxygen and Fluorine?
# Brief Explanations:
Oxygen and Fluorine are both nonmetals, so they form a covalent bond (sharing electrons). Metallic is for metals, ionic for metal-nonmetal, neutral isn't a bond. So covalent.
# Answer: A. Covalent

### Question 8: Which of the following atoms is most likely to form an ionic bond with Nitrogen?
# Brief Explanations:
Ionic bonds form between metal and nonmetal. Nitrogen is nonmetal. Carbon (nonmetal), Hydrogen (nonmetal), Fluorine (nonmetal), Sodium (metal). So Sodium (metal) will form ionic bond with Nitrogen (nonmetal).
# Answer: D. Sodium

### Question 9: Which atom does not follow the octet rule? (Assuming options include Hydrogen, etc.)
# Brief Explanations:
Hydrogen follows duet (2 electrons), but if options have Hydrogen, it might be the one (or others like B, Al). Assuming Hydrogen is an option (as it only needs 2), it doesn't follow octet (follows duet). So Hydrogen (if that's an option) is the answer.
# Answer: (Assuming the option with Hydrogen) Hydrogen (exact option depends on labels, but logic is H doesn't follow octet)

### Question 10: How many total electrons are shared in a double bond between two atoms?
# Brief Explanations:
A single bond shares 2 electrons, double bond shares 4 (2 pairs), triple 6. So double bond shares 4 electrons.
# Answer: D. 4
