it moves from left to right
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
False. The most chemically reactive metals are in the two leftmost columns.
The reactivity is increasing, from left to right - for example halogens.
The family of elements to the far right of the periodic table is called the noble gases. The noble gases include helium, neon, argon, krypton, xenon, and radon. They are known for their low reactivity and stability due to their full outer electron shells.
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!
Decrease reactivity
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
No it decreases.
No, right to left.
False. The most chemically reactive metals are in the two leftmost columns.
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 of nonmetals generally decreases as you move from left to right across the periodic table. This is because nonmetals on the right side of the periodic table have a higher electronegativity, making them less likely to lose electrons and more likely to gain electrons.
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 reactivity is increasing, from left to right - for example halogens.
