Group one elements are generally more reactive than group two elements. This is because group one elements have one electron in their outermost shell, making them more willing to react and form compounds in order to achieve a stable electron configuration. Group two elements have two electrons in their outermost shell, which makes them less reactive than group one elements.
What else can I help you with?
How are group 1 elements different from the group 18 elements?
The difference between group 1 and group 2 metals is that group 1 metals have ONE valence electron and group 2 have TWO valence electrons. This makes a great difference in how they react chemically with other elements and compounds.
How does reactivity change from an element in group 1 to an element in the same period in group 2?
Reactivity decreases from group 1 to group 2 within the same period. Group 1 elements, like lithium and sodium, are highly reactive due to their single valence electron, which they readily lose to form positive ions. In contrast, group 2 elements, such as magnesium and calcium, have two valence electrons, making them less reactive since they require more energy to lose both electrons. Consequently, while both groups are reactive, group 1 elements are generally more reactive than their group 2 counterparts in the same period.
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.
Which element in 1a group is more reactivity?
Francium(Fr) is the most reactive element in Group 1A . The least reactive is Lithium(Li) The element become increasingly reactive 'down' Group 1A. NB You will NOT find francium in a school lab. for two reasons. 1. It explosive when in contact with water. 2. It is 'Radio-active' and radio-active matter has to be kept in special conditions.
Why are all of the elements in group 18 relativity unreaction whereas those in group 17 are very reactive?
Group 18 elements, known as noble gases, have full valence electron shells, which makes them stable and unreactive under normal conditions. In contrast, group 17 elements, or halogens, have seven valence electrons and seek to gain one more electron to achieve stability, making them highly reactive. This difference in electron configuration is the primary reason for the contrasting reactivity of these two groups.
Calcium or bromine which is more reactive?
I believe its Calcium, because it is in group 2, and Bromine is not in group one or two, making Calcium more reactive.
Are group 2 elements highly reactive?
Reactivity increases as you go down the group. Radiom is far more reactive than Beryllium.
How are group 1 elements different from the group 18 elements?
The difference between group 1 and group 2 metals is that group 1 metals have ONE valence electron and group 2 have TWO valence electrons. This makes a great difference in how they react chemically with other elements and compounds.
Which is more reactive group 1 or 2?
Group 1 elements, also known as alkali metals, are generally more reactive than group 2 elements, known as alkaline earth metals. This is because alkali metals have one electron in their outermost shell, making them more willing to lose that electron to achieve a stable electron configuration. Alkaline earth metals have two electrons in their outermost shell, requiring more energy to lose those electrons and become stable.
Is potassium more or less reactive than magnesium?
Very much so. Potassium is one of the most reactive metals on the periodic table, and Zinc is somewhere in the middle in terms of reactivity (not nearly as reactive as alkali metals, much more reactive than precious metals like silver, gold, etc.).
Is it true that transition metals are less reactive than the metals in group one and two of the periodic table?
True
Which two families in the periodic table have the most reactive metals?
The alkali metals (Group 1) and the alkaline earth metals (Group 2) are the two families in the periodic table with the most reactive metals. Alkali metals are more reactive than alkaline earth metals due to their lower ionization energy and higher reactivity with water and air.
Which is more reactive fluorine or barium and why?
Fluorine would be the more reactive element because it needs to gain one electron. While Barium needs to gain two electrons. Thus it is easier to gain one than to lose two.
What are two most reactive elements in the alkali group?
Francium and cesium
Most reactive group in periodic table?
The most reactive goup in the metals is the Alkali metals (Group I) The most reactive non-metal group is Group 17 or VIIA) the Halogens. It is difficult to say which of the two groups is more reactive. Chemists will say that Flourine is the most reactive element. Note that Group 18 is the least reactive, most stable.
Which are least reactive eiter ethers or esters?
Ethers are generally less reactive than esters. This is due to the lack of a reactive functional group in ethers, which mainly consist of an oxygen atom bonded to two alkyl or aryl groups. In contrast, esters contain a carbonyl group (C=O) that makes them more susceptible to nucleophilic attack and hydrolysis. Thus, esters are typically more reactive than ethers.
What is the similarities between alkali metals and alkaline earth metals?
AM are in group one and are very reactive, unstable, and has one electron in the outer shell, where as in AEM they are in group two and have 2 electrons in the outer shell.
