they only need 1 more valence electron to reach 8 which is what all atoms want.

What is the rule for the activity trends of metals and nonmetals?
Metals: the farther to the left the more reactive they are. Group 1 metals, which include sodium and potassium, are so highly reactive that they do not exist in nature by themselves (only in compound form.) Non-metals: the farther to the right the more reactive they are *with the exception of group 18* which are the noble gases and do not react at all. The most reactive are group 17, which include fluorine and chlorine. These non-metals, like group 1, rarely exist by themselves because of their high reactivity.
What is the most reactive element in group 18?
The most active element in Group 17 of the periodic table turns out the be the most reactive element among all of the elements. It's fluorine (F), and we sometimes hear it called the "hungry wolf" of the periodic table because it is so reactive.A link is provided to the Wikipedia post of the periodic table. This table features hyperlinks as part of its makeup. Each chemical element's symbol is a link to the Wikipedia post on that element.
Why are group 7 elements very reactive?
Reactions in chemistry are all about the number of electrons in the outer shell of an atom. Generally the more space it has in this shell the more reactive it will be. Group 1 have only 1 electron in the outer shell, group 8 have 8 (8 is the maximum possible so these elements are not reactive).
Is the group halogens in a periodic table reactive?
Very much so. The only group that isn't reactive is the Noble gases, however even some noble gases will react under the right conditions.
Why is group 17 more reactive than group 16?
The elements of this group do not have a stable number of electrons. - - - - - Group 17, the halogens, are extremely reactive (the only non-reactive elements are in group 18, the noble gases, but group 17 elements are more reactive than other group elements) because of their high "effective nuclear charge." An atom wants to have eight electrons in its outer shell, whether it's because it naturally has that many like the group 18 elements do or because it bonded to other atoms and share electrons with them. The closer to eight an atom has on its own, the higher this charge is - which makes it more reactive. Group 17 atoms all have seven electrons in their outer shells, so they are on the hunt for anything they can possibly grab. For more entertainment, the fewer shells an atom has between its "helium layer" (that lil' shell right around the nucleus with two electrons in it) and the outer shell, the higher this effective nuclear charge is. Because fluorine only has two shells, its effective nuclear charge is as high as it can get...which is why fluorine will react with anything including glass.
Is Br reactive?
Oh yeah. So reactive, in fact, that bromine rarely exists by itself in nature; only locked up in a compound. Bromine is a halogen, group 17, and those are the most reactive of all the non-metals.
The Family of what is the most reactive group of metals in the periodic table?
The Alkali metals are the most reactive group of metals in the periodic table. Of these Francium is the most reactive metal of all.
Why is carbon less reactive than sodium?
Because carbon is in group 14 of the periodic table and sodium is in group 1 so that means that sodium is more reactive because its in group 1 which is more reactive than group 14.
Where are the most reactive nonmetals located?
The most reactive nonmetals are the Halogens. They are located in the second to last row on the periodic table from the right.
What is the most reactive group of elements in the periodic table?
Alkali Metals (group 1) because they only need to lose one electron in order to have a stable valence level of 8. As you go down the alkali metals group, the elements become more reactive. So Francium is the most reactive alkali metal. Also, Halogens, because they already have 7 electrons and only need to gain one in order to have a stable valence level of 8. As you go up the halogens group, the elements become more reactive. So Fluorine is the most reactive halogen. This is just a brief summary, if you want to know the reasons why this is I suggest you search about ionization energy, electron affinity, and electronegativity because these are all what make an element "reactive."

Where are the most reactive element found on the periodic table?
Group 1, or the alkali metals, left of the table and Group 17, the halogens, right of the table are the most reactive groups. Fr, or Francium (atomic number 87) is the most reactive metal- and fluorine the most reactive halogen. Francium and fluorine would react together explosively they are so reactive.
What is the most reactive group of elements?
It is in Group 17 that you will find the most reactive elements. These elements all lack only one electron from having that "magic" electron configuration of the inert gases. That makes these elements very "hungry" to get that "last electron" so their electron structures become more stable.
Is the boron group reactive?
I was checking this question out ... but it told me to answer it .. So heres my answer .. jahbfklsdbfuhklsd I DONT KNOW. Someone nerdy answer this crap.
What group of metals is so reactive that the metals are never found as?
The group you're thinking of is group 1, the alkali metals. They include sodium and potassium, and you're right, they are so reactive that they do not exist by themselves. They only exist in compounds with other elements.
