Decrease reactivity
No it decreases.
No, right to left.
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
If the question means REACTIVITY.. well..no, it decreases across and increses downwards..
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!
True. Generally, the reactivity of metal elements increases as you move from left to right across the periodic table. This is because as you move towards the right, the elements have fewer electrons in their outer shell, making them more likely to lose electrons and react with other elements.
Platinum, iridium, or osmium, all of which are very low in reactivity.
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
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.
For example metal or nonmetal character, radioactivty, atomic weight, reactivity.
On the right side.
False. The most chemically reactive metals are in the two leftmost columns.
