Answer 1

hi buudy ,

1/ Superheavy elements are thoseelements with a large number of protons in their nucleus.Elements with more than 92 protons are unstable; they decay to lighter nuclei with a characteristic half-life.

2/ The f block elements, numbers 57 to 70 and 89 to 102, are calledthe inner transition elementsbecause of their placement in the periodic table due to their electron configurations. ... Thus, the electron configuration for Nd (Z=60) is [Xe] 6s2 4f4. The last electron goes into a 4f orbital which is inside the 6s orbital.

3/It takes very little energy to remove that outermost electron from an alkali metal. Thus, alkali metals easily lose their outermost electron to become a +1 ion. This happens so often that it is rare to find a sample of an alkali metalwith all of its electrons; mostalkali metals occur in their ionic +1 form

Answer 2

Heya.....✋

The elements with atomic numbers 104 to 118 have been discovered recently. These are radioactive, not very stable having high densities are called super heavy elements.

The differentiating electron in f-block elements enters(n-2) subshell which is an inner energy shell and therefore f-block elements are called inner transition elements.

Alkali metal have low ionisation enthalpies and thus, they have the tendency to lose electron easily and therefore, show metallic nature. Halogens possess high electron gain enthalpies and thus, they have the tendency to accept electron to achieve the inert gas configuration and therefore, show non-metallic nature.

hope it helps✅
