The chemistry of actinoids is more complicated as compared to . . . Thus, in the lanthanoids, only 4f electrons of Ce participate in chemical bonding, whereas in the lighter actinoids, up to americium, the 5f electrons also take part This makes the chemistry of actinoids more complicated than that of lanthanoids The reasons are as follows:
Give reason: Chemistry of actinoids is much more complicated than that . . . Hint: Actinoids or actinides are $15$ consecutive chemical elements in the periodic table from actinium to lawrencium As a group, they are significantly large because of their radioactivity Although several members of these groups are man-made elements like uranium, they occur naturally
Chemistry of actinoids is complicated as compared to lanthanoids. Give . . . Chemistry of actinoids is more complicated than lanthanoids because (i) actinoids show greater number of oxidation states due to the comparable energies of 5f, 6d and 7s orbitals (ii) The actinoids are radioactive and the study of their chemistry in the laboratory is difficult
Chemistry of actinoids is complicated as compared to . . . - SaralStudy (i) Actinoid are radioactive due to that, chemistry of actinoid is complicated (ii) 5-f orbital present in actinoids is more exposed to the outer environment while 4-f orbital present in lanthanoide are deeply buried
Chemistry of actinoids is complicated as compared to lanthanoids - Zigya Chemistry of actinoids is complicated as compared to lanthanoids Give two reasons Less tendency towards the complex formation A Strong tendency towards the complex formation All the actinides are radioactive 37 An element has atomic mass 93 g mol –1 and density 11 5 g cm –3 If the edge
Why is the chemistry of actinoids more complicated compared to . . . The chemistry of actinoids is more complex due to a wide range of oxidation states and the complications arising from their radioactivity The occurrence of various oxidation states and the challenges posed by radioactivity make the study of actinoids more intricate
Actinoid contraction is greater from element to element than lanthanoid . . . In actinoids, 5f orbitals are filled These 5f orbitals have a poorer shielding effect than 4f orbitals (in lanthanoids) Thus, the effective nuclear charge experienced by electrons in valence shells in case of actinoids is much more that that experienced by lanthanoids
Compare the chemistry of the actinoids with that of lanthanoids with . . . The chemistry of actinoids is more complicated as compared to lanthanoids Give a reason for the following: Actinoids show irregularities in their electronic configurations How would you account for the following: Actinoid contraction is greater than lanthanoid contraction Why do actinoids show a wide range of oxidation states?
Major Differences between Lanthanoids and Actinoids - Unacademy Even though lanthanoids are classified as rare-earth elements, their abundance in the crust is by no means uncommon, and chemistry based on their unique features is expected to proliferate soon Nuclear chemistry and nuclear energy are both closely related to actinoids
