Zirconium (Zr) is a d-block element, while Uranium, Plutonium, and Neptunium are f-block elements.

Carbon dioxide (CO2) is not a hydrogen compound as it does not contain hydrogen.

Sodium is an s-block element, while the others are p-block elements.

F-block elements are generally magnetic due to unpaired electrons, so 'Non-magnetic' is not a property.

Hydrogen is not highly soluble in water; it is actually sparingly soluble.

Ionic compounds do not conduct electricity in solid state; they conduct when molten or dissolved.

Zinc is not considered a transition metal because it does not have an incomplete d subshell in its elemental state.

Calcium is not an alkali metal; it is an alkaline earth metal.

Aluminum is not an s-block element; it is a p-block element.

Cesium (Cs) is the heaviest alkali metal.

Fluorine is the most electronegative element in the p-block.

Neodymium is used in making strong permanent magnets due to its magnetic properties.

CN- is a strong field ligand and causes a large splitting of d-orbitals, leading to low-spin complexes.

Fluorine has the highest electronegativity among all elements.

Boron is a metalloid among the p-block elements.

Phosphorus is essential for life, particularly in DNA and ATP.

Boron is an essential micronutrient for plant growth.

Tin (Sn) is known for forming a stable +4 oxidation state.

Aluminum commonly forms stable +3 oxidation state compounds.

Thallium is known for forming a stable +3 oxidation state.

Cerium (Ce) and Lanthanum (La) are both f-block elements.

Cerium (Ce) and Lanthanum (La) are both lanthanides, which are f-block elements.

Lead is a heavy metal that can be toxic to humans and the environment.

Volatile Organic Compounds (VOCs) are major contributors to smog formation, especially in urban areas.

Ozone at ground level is a major component of smog, formed by the reaction of sunlight with pollutants.

Nitrogen Dioxide is a major contributor to the formation of smog, particularly in urban areas.

Nitrogen Dioxide (NO2) is associated with respiratory problems and is a significant air pollutant.

Nitrogen dioxide is a key contributor to the formation of smog, especially in urban areas.

Sulfur oxides (SOx) and nitrogen oxides (NOx) are the main pollutants that contribute to the formation of acid rain.

Lithium has the highest melting point among the alkali metals due to its small size and strong metallic bonding.
