\nThe correct option is C, 2 4 3 1.
\n<\/section>\n
\nLet’s match the elements with their uses:
\nA. Li (Lithium): Lithium is a highly reactive alkali metal widely used in batteries, particularly rechargeable lithium-ion batteries that power portable electronic devices, electric vehicles, etc. This matches characteristic 2. (A-2)
\nB. Na (Sodium): Sodium ions (Na+) are essential electrolytes in the body. They play a critical role in regulating blood pressure and the control of water balance in the blood and body tissues through osmosis. This matches characteristic 4. (B-4)
\nC. K (Potassium): Potassium ions (K+) are also essential electrolytes involved in various bodily functions, including the transmission of nerve impulses and muscle contractions (along with sodium ions). This matches characteristic 3. (C-3)
\nD. Cs (Cesium): Cesium is an alkali metal, and the isotope Cesium-133 is famously used in atomic clocks due to the highly stable frequency of radiation emitted during electron transitions in its atom, which defines the length of a second. This matches characteristic 1. (D-1)
\nThus, the correct matching is A-2, B-4, C-3, D-1, which corresponds to option C (2 4 3 1).
\n<\/section>\n
\nElements have a wide range of applications based on their unique chemical and physical properties. Lithium, sodium, and potassium are alkali metals known for their reactivity. Cesium is the heaviest stable alkali metal and is known for its very low ionization energy, making it useful in applications like atomic clocks and photocells.<\/p>\n","protected":false},"excerpt":{"rendered":"
