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 , and thus display similar properties, and similar chemistry.

While there are of course significant differences, the chemistry of $Li$ is similar to that of the lower alkali metals, the chemistry of the alkaline earth metals forms a category, and across the Table to the non-metals. each Group represents a distinct valence , and a distinct chemistry.

Do elements have similar chemical and physical properties when they are located in the same group or period?

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,...

Are elements with similar chemical properties more likely to be found in the same period or in the same group?

The of a group have similar chemical properties but in a period they have different chemical properties. This is because the chemicals properties depend on no of . As in...

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

The periodic trend states that in the same group (column) in have similar properties.

Which group on the Periodic Table of the Elements contains elements that react with oxygen to form compounds with the general formula $X_2O$?

Including Hydrogen (though Hydrogen is sometimes not put obviously as part of group 1)

What is the similarity in chemical properties of the atoms of elements in a group of the periodic table is most closely related to?

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.......

Do elements in the same row across belong to the same period or group?

Periods run horizontally, left and right. Groups run vertically, up and down. Groups are also called families because the groups share some characteristics. As an example, all the of Group...

To which group in the periodic table does lithium belong? How many valence electrons does it have?

The groups of are organized in columns (from top to bottom) and some have specific names, while some are part of a larger grouping. For example, group one is the...

For the main group elements (excluding the transition elements), is it necessary memorize to memorize the type of ion each element makes or could you predict the Ion charge using a periodic table?

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...

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

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...

Does electronegativity increase or decrease when you go a period on the periodic table? Does it increase or decrease when you move down a group on the periodic table?

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...
