Rationale: Matter is composed of atoms which combine to form
molecules and compounds.
Correct answer: B
2. Which subatomic particle carries a negative charge?
A. Proton
B. Neutron
C. Electron
D. Nucleus
Rationale: Electrons are negatively charged particles located
outside the nucleus.
Correct answer: C
,3. The atomic number represents the number of:
A. Neutrons
B. Protons
C. Electrons and neutrons
D. Mass units
Rationale: Atomic number equals the number of protons in the
nucleus.
Correct answer: B
4. A covalent bond is formed by:
A. Transfer of electrons
B. Sharing of electrons
C. Transfer of protons
D. Sharing of neutrons
Rationale: Covalent bonds involve shared electron pairs
between atoms.
Correct answer: B
