it moves from left to right
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
Reactivity increases the farther down you go in the Periodic Table.
yes, it is a non metal and it is placed on the right side of the Periodic Table, reactivity increases from left to right on the periodic table. since selenium is in group 16 out of 18 groups, it is a very reactive element. hope this helps you!
The reactivity is increasing, from left to right - for example halogens.
Reactivity of non-metals increases as you move from left to right on the periodic table, or as group number increases. The most reactive non-metals are found in group 17.
Decrease reactivity
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
No it decreases.
The most reactive nonmetals are located in top most right section of the Periodic Table, excluding group 18 (has no reactivity).
No, right to left.
Reactivity increases the farther down you go in 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.
Maybe there is no pattern...no it fals
The metals on the left side of the periodic table are considered to be highly reactive to air while in room temperature. The ones on the right side are less reactive and are often used for construction.
The reactivity is increasing, from left to right - for example halogens.
Reactivity of non-metals increases as you move from left to right on the periodic table, or as group number increases. The most reactive non-metals are found in group 17.
