Yes. This is due to the fact that their valence shells are adding electrons, coming closer to having an octet. The halogens in group 17/VIIA are the most reactive nonmetals because they have seven valence electrons and readily react in order gain the eighth valence electron, which gives them an octet like the nearest noble gas. It takes much less energy to gain one electron or share one electron, than it does to gain or share two or more electrons.
What else can I help you with?
What happens to the reactivity nonmetals as you move down a period?
The reactivity is increasing, from left to right - for example halogens.
Do the elements go from metals to nonmetals or nonmetals to metals?
Moving from left to right on the periodic table, the elements generall go from metal to nonmetals.
How are elements arroanged on the periodic table?
metals are on the left nonmetals are on the right and the metalloids are in the middle. Here is a saying to help you remember metals on the left, nonmetals on the right the metalloids keep them from getting in a fight
Where are the metals and nonmetals located on the peridoic table?
Metals are located on the left side of the periodic table, while nonmetals are located on the right side. There is a diagonal line dividing the metals and nonmetals, with metalloids lying along this line.
How do most periodic tables differentiate between metals and nonmetals?
Most periodic tables differentiate between metals and nonmetals by placing the metals on the left and in the middle of the table, and the nonmetals on the right. The dividing line between metals and nonmetals is often marked by a zigzag line that separates the two categories, with elements to the left being metals and elements to the right being nonmetals.
What happens to the reactivity nonmetals as you move down a period?
The reactivity is increasing, from left to right - for example halogens.
What happens to the reactivity of non metals if you move from left to righton the periodic table?
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.
Why metals become more reactive as you move from left to right across the periodic table?
They don't
Is unreactivity a property of metal?
No, because metals are on the left side of the Periodic Table. Therefore, they are reactive. Nonmetals, on the left side of the Periodic Table, are less reactive, because they have more valence electrons.
How does reactivity of elements change across the periodic table?
this is called periodicity, the chemical properties of elements as you go across a period. The reactivity would be very great at first, especially if you are only crossing main group elements, and then would become less reactive, then very reactive again, and then one group over they would be completely inert
Do the elements go from metals to nonmetals or nonmetals to metals?
Moving from left to right on the periodic table, the elements generall go from metal to nonmetals.

Metals are located on the left side of the periodic table, while nonmetals are located on the right side. There is a diagonal line dividing the metals and nonmetals, with metalloids lying along this line.
What happens to the reactivity of metals from left to right across the perriodic table?
Elements become less reactive as you move from left to right across the periodic table. This is due to how many valence electrons (outer-most electrons) the element has; the less valence electrons, the more reactive the element.
Where are metals and nonmetals are located on the periodic table?
Non-metals are located on the very right of the Periodic Table. Metals are on the left.
What happens to the reactivity of elements in groups as the atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
Name the two types of elements from left to right?
