WebThe periodicity in properties of elements in any group is due to repetition in the same valence shell electronic configuration after a certain gap of atomic numbers such as 2, 8, 8, 18, 18, 32. The atomic number of Al is 13 and its electronic configuration is 2,8,3. So, the electronic configuration of Al 3+ is 2,8. WebThe electron configuration of an element can be written using the notation [noble gas] ns^2np^6, where the noble gas represents the electron configuration of the preceding noble gas element, and ns^2np^ represents the valence shell electrons. ... The perio dic table reflects trends in electron configuration and chemic al proper ties. Within a ...

WebFinal answer. Step 1/6. Here we have Given. Here we have to write the electronic configuration for the given atom and ions by using noble gas core abbreviations. For example :-. Fe = [Ar]4s (2)3d (6) Sn 2+ = [Kr]4d (10)5s (2) S 2- = [Ar] Here we have to write the electronic configuration for these atoms and ions. WebThus, the charge of a cation formed by the loss of all valence electrons is equal to the group number minus 10. For example, aluminum (in group 13) forms 3+ ions (Al 3+ ). As always, there are exceptions. Click here to learn more! Transition and inner transition metal elements behave differently than main group elements. WebAl 3+, it loses 3 electrons from its outermost energy shell. In this case, the 3 electrons will come from the third energy shell. To be precise these electrons will come from. one 3p … shreveport la weather january
