Which radioactive emission has the highest ionizing power?
A. Beta
B. Gamma
C. Alpha
D. X-rays
Answer: Option C
Solution (By JKSSB Mock Tests)
Alpha particles, being heavy and doubly charged, cause intense ionization over a short distance. They are least penetrating. Gamma has low ionization but high penetration.
Explanation:
Graham's law of effusion/diffusion applies to gases. It states that rate is inversely proportional to square root of molar mass. It is used to separate isotopes.
Explanation:
Saline water (containing NaCl) increases the electrical conductivity of the water, accelerating the electrochemical process of rusting. This is why ships and coastal structures rust faster. Dry air and vacuum have no moisture; pure water without dissolved oxygen slows rusting.
Explanation:
Metallic bonds are formed by the electrostatic attraction between positive metal ions and a 'sea' of delocalized valence electrons. These bonds are non-directional, which allows the metal ions to slide past one another without breaking the bond, explaining malleability and ductility. Therefore, statement C is incorrect.
