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.
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.
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 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.
Where are the most reactive nonmetals located?
The most reactive nonmetals are located in Group 17 (halogens) of the periodic table. These elements include fluorine, chlorine, bromine, iodine, and astatine. They are highly reactive due to their tendency to gain an electron to achieve a stable electronic configuration.
The Family of what is the most reactive group of metals in the periodic table?
The most reactive group of metals in the periodic table is Group 1, the alkali metals. These metals are highly reactive due to their low ionization energies, which means they readily lose their outermost electron to form positive ions. This reactivity increases as you move down the group due to the decreasing ionization energies.

What is the most reactive group of elements in the periodic table?
The alkali metals, group 1 elements, are the most reactive group of elements in the periodic table. They readily lose their outermost electron to achieve a stable electron configuration, resulting in highly reactive behavior.
Is the boron group reactive?
The boron group (Group 13) is moderately reactive compared to other groups. This reactivity increases as you move down the group, with boron being the least reactive and thallium being the most reactive. Boron has a strong affinity for oxygen, so it readily forms oxides when exposed to air.
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.
Which of the following groups in the periodic table contain elements so reactive that they are never found in the free state?
Group 1 (alkali metals) and Group 17 (halogens) in the periodic table contain elements that are highly reactive and are never found in their free state in nature. Alkali metals readily react with water or air, while halogens are highly reactive nonmetals that form compounds with other elements quickly.
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.
Which is more reactive barium magnesium or beryllium?
Barium is more reactive than magnesium, and beryllium is less reactive than both. Reactivity generally increases as you move down a group on the periodic table, so barium is more reactive than magnesium due to its position in the same group.
Why is most reactive nonmetal are found in group 17?
All metals react with other elements by losing their outermost electrons in their atoms forming 'positive ions'. So the ease with which they can lose these electrons gives us an indication of how reactive they are. Aluminium, as an example has three electrons in the outer orbits of each aluminum atom, and so three have to be lost for the aluminum to react. Calcium, a more reactive metal has only 2 electrons in the outermost orbits of its atoms, and so these are more easily lost, making calcium more reactive. However all group 1 elements (Lithium, Sodium, Potassium, Rubidium, Caesium, Francium) all have just one electron in the outermost orbits of their atoms, and so they are the most reactive of all metals as this one electron is very easily lost. More than this, the reactivity gets stronger as the atoms get larger (as you proceed down the group) because the outermost electron is further away from the nucleus and is therefore less strongly bound to the atom than the outermost electron in smaller atoms like lithium as the electron is closer to the nucleus and more tightly bonded to the rest of the atom. This means that Lithium is the least reactive of the Group 1 elements and Francium the most reactive. Francium is radioactive and does not exist in large quantities, so practically caesium is the most reactive. Lithium, when placed on the surface of some water fizzes vigorously. However, caesium, when placed in a glass trough of water explodes violently, with enough force to shatter the trough and possibly damage greatly the surrounding area too.
