Where would you find elements with similar properties located on the periodic table?

can predict the properties of new , because it organizes the elements according to their atomic numbers. Creating new elements is not a simple process. Scientists use a particle...

The $"Periodic Table"$ reflects electronic structure; i.e. specifically the number and symmetry of the . Given the same number of , elements of the same Group should exhibit similar chemistry,...

They are found in the second group of . Note that metallic periodic tend to decrease across a period and increase down a group.

Atoms from the same Group of have the same number and symmetry of , and this electronic similarity should give rise to similar chemistry. And indeed it does.......

The modern Periodic Table graphically describes the electronic structure of the . To a first approximation, elements that are members of the same Group have the same number of ,...

Well, it's Group 15. The mnemonic for this Group is, $"no passers by"$, i.e. $"nitrogen, phosphorus, arsenic, antimony, bismuth"$. Why do we use this mnemonic?

The Group number represents the number of . And thus the alkali metals have the ONE valence electron, and the alkaline earths have TWO . And typically, they lose...

And electronic structure directly influences the observed chemistry. And thus is divided into Groups, i.e. the vertical columns, whose members have more or less the same number of , and...

As we face , increases ACROSS the Period from LEFT to RIGHT, BUT DECREASES down a Group, a column of the the Periodic Table. So why? Well, we will first...

Just take a look! Oxygen, sulfur, the halogens ... these all frequently form negative ions when reacted with, say, a metal, to form a salt through . The rough explanation...
