- 826 Views. Alkali metals are so reactive because of their low ionisation energy.It is the energy required to detach the outermost electron from an atom.And in usual reactions a metal loses its electron to form compound.

Metals Alkali metals react violently with water, halogens, and acids. The reactions release surprising amounts of heat and light. Alkali metals react with oxygen to form oxides, which have a duller appearance and lower reactivity. The oxides are much less reactive than the pure metals.

Alkali metal The alkali metals are a group (column) in the periodic table consisting of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).n the modern IUPAC nomenclature, the alkali metals comprise the group 1 elements, excluding hydrogen (H), which is nominally a group 1 element but not normally considered to be an alkali metal as it rarely exhibits behaviour comparable to that of the alkali metals.

Alkali metals Photo by: concept w. The alkali metals are the elements that make up Group 1 of the periodic table: lithium, sodium, potassium, rubidium, cesium, and francium. These elements are all much too active to exist in nature in their native state.ecause the alkali metals all have one electron in the outer orbit of their atoms, they have similar chemical and physical properties.

What Is the Most Reactive Metal in the Periodic Table? A: The most reactive metal in the periodic table is francium. Francium belongs to the alkali metals, a group on the periodic table whose members are all highly reactive. These metals are highly reactive because they all have only one valence electron.

- Many elements are classified as metals. Recall that. metals can conduct heat and electricity. Most metals can. be stretched and shaped into flat sheets or pulled into. wires. Families of metals include the alkali metals, the. alkaline-earth metals, and the transition metals. THE ALKALI METALS. The elements in Group 1 form a family called the. alkali metals. Because their atoms have only one. valence electron, the alkali metals are very reactive. The. valence electron can be easily removed to form a cation. such as Na or K. Alkali metals also have similar. physical properties, such as melting point, boiling point, and density.

What's the difference between alkali metals and alkaline earth metals and transition metals? The alkaline earth metals are a group of chemical elements in the periodic table with very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure and readily lose their two outermost electrons to form cations with charge +2.he alkaline earth metals are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

- The alkali metals are found on the left edge of the periodic table. Because alkali metals are so reactive, they are rarely. found in nature as pure elements. Rather, they are found. combined with other elements as compounds. For exam-. ple, the alkali metal sodium is found in the salt sodium. chloride, NaCl.

Which of the following statements about alkali metals is true? Fraizie has it right. Alkali metals are all highly reactive (D is false) so they would not be found in their uncombined form (A is false) ans at least some of them are highly water soluble (C is false) so only B is left.Check out the Periodic Table-you will see the Alkali metals.est Answer: It is B! The group of elements called alkali metals are in the first column, or group, of the periodic table.

Alkali metal Hence, all the alkali metals are soft and have low densities, melting and boiling points, as well as heats of sublimation, vaporisation, and dissociation They all crystallize in the body-centered cubic crystal structure, and have distinctive flame colours because their outer s electron is very easily excited.

Group 1: Hydrogen and the Alkali Metals Alkali metals are the chemical elements found in Group 1 of the periodic table. The alkali metals include: lithium, sodium, potassium, rubidium, cesium, and francium. Although often listed in Group 1 … Alkali metals are the chemical elements found in Group 1 of the periodic table. The alkali metals include: lithium, sodium, potassium, rubidium, cesium, and francium. Although often listed in Group 1 due to its electronic configuration, hydrogen is not technically an alkali metal since it rarely exhibits similar behavior.

What are the most reactive elements on the periodic table? As you go down the alkali metals group, the elements become m … ore 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.

Alkali Metals and Halogens The common thing in both alkali metals and halogens is the chemistry of loosing and gaining the electrons. Since the alkali metals and halogens comes under 1st group and 17th group, they have one electron and seven electrons in the outermost shell.eactivity of Alkali Metals and Halogens In the outermost (s) shell of the alkali metals, they have 1 electron, by loosing that electron, the alkali metals get the stable electronic configuration.

metal Rare Earth Elements. The alkali metals, found in group 1 of the periodic table (formerly known as group IA), are very reactive metals that do not occur freely in nature. These metals have only one electron in their outer shell. Therefore, they are ready to lose that one electron in ionic bonding with other elements. As with all metals, the alkali metals are malleable, ductile, and are good conductors of heat and electricity. The alkali metals are softer than most other metals. Cesium and francium are the most reactive elements in this group.

- Some investigators might think that the most reactive metal is francium. This is not unreasonable, since the trend of increasing atomic radius and electron shielding of the nu … clear charge as the number of shells increases will decrease ionization energy on moving down Group 1. But caesium is more reactive. The metal francium, which is in Period 7 of Group 1, has such a large outer shell, that valence electrons move at relativistic speeds. The lower electron density of the outermost shell offsets much of the electron shielding by core electrons.

- 0. Metals like sodium, potassium and lithium are highly reactive and react with air at room temperature. So, in order to break their contact with air, they are stored in liquid hydrocarbons like kerosene oil, as kerosene is lighter than any of these metals.Hope this help!!ecause these are highly reactive metals and could catch fire by reacting with oxygen in the presence of air. ...........that 's why they are stored under oil to prevent their contact with oxygen.

Alkali Metals to the Left But wait. That element is NOT in the family. When we told you about families, we said that they were groups of elements that react in similar ways. Hydrogen is a very special element of the periodic table and doesn't belong to any family. While hydrogen sits in Group I, it is NOT an alkali metal. Now that we've covered that exception, the members of the family include: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs) and francium (Fr). As with all families, these elements share traits. They are very reactive.

Alkali metal The alkali metals, halogens and noble gases are three important groups in the periodic table. The alkali metals are soft, reactive metals. They react vigorously with water and become more reactive as you go down the group.The halogens are reactive non-metals.They become darker as you go down the group.he elements in group 1 are called the alkali metals. They belong to the left-hand column in the periodic table. They are very reactive and must be stored in oil to avoid contact with air or water.
