Moving from left to right across a period, up to but not including the noble gases (group 18), reactivity increases. Moving down a group, the reactivity of the elements decreases. Fluorine is the most reactive element.

What does anion do as you go across the periodic table?
An anion, simply carries across the atom numbers, in greater size. But that is only with the metals, with non-metals, the numbers are arranged by how less the number is. So the higher the atom number, the further across will the anion be on the Periodic table but with non-metals, the less the atom number the closer to the metal section will the anion be on the Periodic table.
What happens to the reactivity of left to right across the periodic table?
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
Where are the metals found on the periodic table?
in the middle or they are closer to the leftMetals are on the left side and are the majority of all elements.
What are the elements in the periodic table most classified as?
Elements of the periodic table
What on the periodic table metals are listed on the?
On the periodic table metals are listed on the left side.
What happens to the state of matters you go across the periodic table?
Across the period (left to right), the elements tend to change from solids (metals) to gases (non metals).

What happens to the reactivity of metals from left or right across the periodic table?
Reactivity decreases from left to right.Alkali metals on the left are most reactive.While noble gases on the right are least reactive.
What do you notice about the boiling points as you move from left to right across the periodic table?
The trend of boiling points across a period in the periodic table should decrease from metals to nonmetals. The trend becomes more complicated between metals, the boiling point of metals tends to increase across a period.

What happen if you move left to right a across a periodic table in metals?
Across a period the metallic character decreases
Where are transition metals located in the periodic table?
Transition metals are located in group 3-12 of the periodic table. The middle of the periodic table.
Are the majority of elements on the periodic table are metals?
The majority of elements in the Periodic Table are metals.
What on the periodic table metals are listed on the?
On the periodic table metals are listed on the left side.
Where are the 3 regions of the periodic table located?
The periodic table comprises of metals (on the left) ,non-metals(on the right ) and transition elements (between metals and non-metals) in the periodic table.
