The peripheral nervous system (PNS) serves as the communication link between the central nervous system (CNS) and the rest of the body. Comprising sensory and motor neurons, the PNS conveys information bidirectionally. Sensory neurons transmit signals from sensory organs to the CNS, providing information about the external environment and the body’s internal state. Motor neurons carry commands from the CNS to muscles and glands, regulating voluntary and involuntary movements. Nerves, bundles of these neurons, act as communication pathways, ensuring the seamless flow of information. The PNS enables the CNS to monitor, interpret, and respond to stimuli from the body’s surroundings, facilitating coordinated physiological functions.
Acidified permanganate solution (MnO₄⁻/H⁺) is a potent oxidizing agent in various reactions. With oxalates, it undergoes a redox reaction, producing carbon dioxide and manganese(II) ions. In the presence of iron(II), it oxidizes to form iron(III) ions. Nitrites are oxidized to nitrogen oxides, and iRead more

In the presence of iron(II), it oxidizes to form iron(III) ions. Nitrites are oxidized to nitrogen oxides, and iodides are oxidized to iodine. These reactions showcase the versatility of permanganate in accepting electrons and undergoing reduction while oxidizing other substances. The vibrant color change from purple (permanganate) to colorless or brown indicates the reduction of manganese(VII) to manganese(II) ions during the redox transformations.
The f-block comprises the lanthanides and actinides, both series of inner transition metals. The lanthanides, also known as lanthanoids, include elements with atomic numbers 57 to 71, starting with lanthanum (La).

The f-block comprises the lanthanides and actinides, both series of inner transition metals. The lanthanides, also known as lanthanoids, include elements with atomic numbers 57 to 71, starting with lanthanum (La). In discussions of the lanthanoids, lanthanum is often treated separately due to its lack of f-electron involvement. Lanthanum is usually considered a part of the d-block and is not categorized with the other lanthanides in terms of f-orbital characteristics. This differentiation arises because lanthanum has a 5d¹ configuration instead of the characteristic f-orbital configuration seen in the rest of the lanthanides.
Lanthanoids, or lanthanides, differ from ordinary transition elements due to their electron configurations that involve filling 4f orbitals. Unlike ordinary transition metals, they exhibit similar chemical properties due to the shielding effect of the filled 4f orbitals, making small changes in sizeRead more
Lanthanoids, or lanthanides, differ from ordinary transition elements due to their electron configurations that involve filling 4f orbitals. Unlike ordinary transition metals, they exhibit similar chemical properties due to the shielding effect of the filled 4f orbitals, making small changes in size and nuclear charge more prominent in their chemistry. The lanthanoid contraction, caused by poor shielding of outer electrons, results in similar sizes for consecutive lanthanoids. This unique characteristic provides an excellent opportunity to study the effects of small changes in size and nuclear charge, allowing researchers to investigate the intricate relationships between electronic structure, reactivity, and physical properties in these elements.
