Li | Soft metal |
Code :
PQRS
Options:
Answer:
Solution:
He has the highest ionization energy. F has the highest electronegativity. Cl has the highest negative electron gain enthalpy. Li is a soft metal. All matches are correct as given.
Explanation:
1. Helium (He) is a noble gas with a very stable electron configuration, making it difficult to remove an electron, hence it has the highest ionization energy.
2. Fluorine (F) is the most electronegative element due to its small size and high nuclear charge, strongly attracting electrons in a bond.
3. Chlorine (Cl) has the highest negative electron gain enthalpy because its electron affinity is slightly higher than fluorine due to less electron-electron repulsion in its larger 3p subshell compared to fluorine's 2p subshell.
4. Lithium (Li) is an alkali metal, known for being soft and easily cut with a knife due to its metallic bonding and large atomic radius.
