Why do you think orbital notation is rarely used for atoms with more than ten electrons?

2b2t

explanation:

2b2t

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)

c. orbital shape i hope this is correct

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
