Why do elements with similar properties appear at regular intervals in the periodic table?

Answer 1

Because the modern Periodic Table directly reflects electronic structure.....

The Periodic Table is therefore divided into Groups, or the vertical columns, whose members have roughly the same number of valence electrons and roughly similar chemistry. More of this will be covered in your text. And electronic structure directly influences the observed chemistry.

Because the number of valence electrons in an element determines its chemical behavior, similar elements appear at regular intervals in the periodic table; additionally, elements with similar valence electron configurations are grouped together in columns or groups.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
