Answer:
No photoelectric effect is observed for Mercury.
Explanation:
From E= hf
h= Plank's constant
f= frequency of incident light
Threshold Frequency of mercury= 435×10^3/ 6.6×10^-34 × 6.02×10^23
f= 11×10^14 Hz
The highest frequency of visible light is 7.5×10^14. This is clearly less than the threshold frequency of mercury hence no electron is emitted from the mercury surface
Answer: 3p Orbitals
Explanation:
Electrons present in the 3p orbitals are farthest from the nucleus. Therefore, the electrons present in the 3p orbital will be shielded by the electrons present in the inner orbitals. Hence, 3p orbital in sulfur is most shielded from the nuclear charge".
Explanation:
Chemical properties are those properties that tells us about what a substance can do as regards to whether or not the substance reacts with other substances.
- Chemical properties are a function of the electrons contained in an atom and how they interact with other atoms.
- Examples of chemical properties are:
- Flammability
- Rusting of iron
- Precipitation
- Decomposition of water by an electric current
