What is the correct order from most reactive to least in platinum copper and silver?
Yes. Platinum is one of the least reactive metals.
What elements are more reactive than lead?
In the group 2 elements, the reactivity of the metals increase as you move down the group. The order of reactivity in group 2 is barium, strontium, calcium, and magnesium.
What metal is more reactive than lead but less reactive than zinc?
In between these two, there are nickel, tin lead and hydrogen.They all are more reactive than copper but less reactive than iron.For your convenience, here is the reactive series of elements in order of decreasing reactivity:-Potassiumsodiumbariumcalciummagnesiumaluminiummanganesezincironnickeltinleadhydrogencoppermercurysilvergoldplatinum
What is the group order of alkali metals by reaction?
Francium is the most reactive chemical element; unfortunately is extremely rare and currently not available for chemical experiments. Also is very radioactive. Lithium, Sodium, Potassium, Rubidium, Caesium, Francium
Which is the second most reactive halogen?
Chlorine is the second lightest member of the halogen elements or group 17.
Place these elements in order from leat reactive yovmost reactive neckel xenon lithium how did you determine the order?
In order from least reactive to most, the order is xenon, nickel, then lithium. I determined this based in the theory that non-metals are less reactive.
Which of the two halogens shown is more reactive?
The most reactive halogen, and one of the most reactive of all the elements, is fluorine. Reactivity in the halogen family continues in order from most reactive to least reactive with chlorine, bromine, iodine, and astatine.
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."
What is the link between displacement reaction and the reactivity series?
the reactivity series lists elements in order from most reactive to least reactive. in a displacement reaction, a more reactive element will "displace" a less reactive element in a compound, the reactivity series can therefore be used to determine which displacement reactions are possible.
What is the correct order from most reactive to least in platinum copper and silver?
Yes. Platinum is one of the least reactive metals.
What elements are more reactive than lead?
In the group 2 elements, the reactivity of the metals increase as you move down the group. The order of reactivity in group 2 is barium, strontium, calcium, and magnesium.
Iodine is a highly reactive blank metal gas?
Iodine is not a metal, and not a gas. It is a representative element in Group 7A of the Periodic table of elements. This group is called the halogen group. Iodine is reactive because it wants to gain one more electron in order to fill its valence shell.As far as properties of elements go, "metal-like" properties of elements increase as you go down a group. Iodine is not a metal but is more metal-like than the halides above it in its group ( it is a liquid, they are a gas. Liquid is closer to metal than gas is.)
How many elements in group will have the order equal to the order of group?
Number of generators of that group
What 4 alkali metals are the most reactive?
Alkali metals have increasing reactivity going down the group. Francium may not be considered as it is not a stable atom: it is radioactive. The next four are Cesium, Rubidium, Potassium and Sodium in decreasing reactivity order.
What are the important features of mendeleev's periodic table?
The periodic table is arranged in the order of increasing atomic numbers of the elements. It starts from an alkali metal and end at an inert gas. The next element is again an alkali metal and is placed just below the previous alkali metal. Sodium (Na), Potassium (K), etc are examples of alkali metals and Helium (He), Krypton (Kr), etc are examples of inert gases. The horizontal lines of elements form a period and the vertical ones form a group. Elements falling under the same group show similar chemical properties. Group 1 elements are called Alkali metals they all have one electron in their outer shell, they are the most reactive elements with Lithium been the least and Francium been the most reactive element. The elements are arranged from top to bottom with lithium at the top and francium at the bottom.
What is the order of the cyclic group mean?
The order of a cyclic group is the number of distinct elements in the group. It is also the smallest power, k, such that xk = i for all elements x in the group (i is the identity).
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.
