Why are they called the alkaline earth metals?

Alkaline earth metals get the name 'alkaline' because of the basic nature of the compounds they form when bonded with oxygen. Alkaline earth metals have relatively low ionization energies for their first two electrons; because of this, alkaline earth metals exist with a 2+ charge most of the time.
A.

Which element is a member of the alkaline earth metals?

The Alkaline Earth Metals are:
  • Beryllium.
  • Magnesium.
  • Calcium.
  • Strontium.
  • Barium.
  • Radium.
  • What are the uses of alkaline earth metals?

    Alkaline earth metals refer to a group of elements in the periodic table. They include beryllium, magnesium, calcium, strontium, barium, and radium. Main uses of these elements are given below. Beryllium: It is used in small amounts to make copper beryllium alloy that are very strong and hard.
  • What is the electron configuration of the alkaline earth metals?

    These elements have two valence electrons, both of which reside in the outermost s sublevel. The general electron configuration of all alkaline earth metals is ns2. The alkaline earth metals are still too reactive to exist in nature as free elements, but they are less reactive than the alkali metals.
  • How are alkali metals and alkaline earth metals different?

    Because group I A elements have valency 1, they can easily give up 1 electron to achieve stability and are thus highly reactive (more reactive than alkaline earth metals). They all react with water to form strongly alkaline hydroxides. Hence group I elements are called Alkali metals.
B.

Are the alkaline earth metals reactive?

They are beryllium, magnesium, calcium, strontium, barium, and radium. They are less reactive than alkali metals, but they form (except for beryllium) alkaline oxides and hydroxides. Alkaline earth metals all have two valence electrons, and they easily oxidize to the +2 state.
  • What do the alkaline earth metals react with?

    Magnesium (Mg) reacts with water vapor to form magnesium hydroxide and hydrogen gas. Beryllium (Be) is the only alkaline earth metal that does not react with water. This is due to its small size and high ionization energy in relation to the other elements in the group.
  • What are the common properties of alkaline earth metals?

    Some characteristics of alkaline earth metals are:
    • An oxidation number of +2 which makes them very reactive.
    • Not found freely in nature.
    • Present in the earth's crust but not in their basic form.
    • Distributed in rock structure.
    • Two electrons in their outer shell.
    • High boiling points.
    • High melting points.
    • Low density.
  • Are alkaline earth metals good conductors of electricity?

    The alkaline earth metals, like the alkali metals, are too reactive to be found in nature except as their compounds; the two valence electrons completing an s-subshell are readily lost, and ions with +2 charges are formed. Like most metals, they are good conductors of electricity .
C.

What are the properties of the alkaline earth metals?

Properties of Alkaline Earth Metals
  • shiny.
  • silvery-white.
  • somewhat reactive metals at standard temperature and pressure.
  • readily lose their two outermost electrons to form cations with a 2+ charge.
  • low densities.
  • low melting points.
  • low boiling points.
  • Are there any man made elements?

    Anything with an atomic number greater than 92 (Uranium), is called transuranic. These elements are manmade, but is there a difference in any way besides that? How are these elements created? However, it has been verified that some of these elements are produced and found in nature in very small amounts.

    • High boiling points.
    • High melting points.
    • Low density.
  • Are alkaline earth metals good conductors of heat and electricity?

    As with all metals, the alkali metals are malleable, ductile, and are good conductors of heat and electricity. The alkaline earth elements are metallic elements found in the second group of the periodic table. All alkaline earth elements have an oxidation number of +2, making them very reactive.
