What elements are in the alkaline earth metals family?

What elements are in the alkaline earth metals family?

Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

What group is the alkaline earth metals family?

Group 2
alkaline-earth metal, any of the six chemical elements that comprise Group 2 (IIa) of the periodic table. The elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

What are 5 characteristics of alkaline earth metals?

Summary of Common Alkaline Earth Properties

  • Two electrons in the outer shell and a full outer electron s shell.
  • Low electron affinities.
  • Low electronegativities.
  • Relatively low densities.
  • Relatively low melting points and boiling points, as far as metals are concerned.
  • Typically malleable and ductile.

Why are the elements of Group 2 called alkaline earth metals?

Solution : Group 2 elements except beryllium are known as alkaline earth metals. These are so called because their oxides and hydroxides are alkaline in nature and these metal oxides are found in Earth. s crust.

What are the characteristics of alkali metals?

The alkali metals have the high thermal and electrical conductivity, lustre, ductility, and malleability that are characteristic of metals. Each alkali metal atom has a single electron in its outermost shell. This valence electron is much more weakly bound than those in inner shells.

Which elements make up a family?

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties.

What are Element families?

Element families are elements that have the same number of valence electrons. Most element families are a single column of the periodic table, although the transition elements consist of several columns, plus the elements located below the main body of the table.

What are 3 similar properties of these elements alkali metals?

Alkali metals share many similar properties including:

  • They are shiny, soft, metals.
  • They are very reactive.
  • They all have one valence electron in the outermost shell which they seek to lose in order to have a full outer shell.
  • They are soft enough to be cut with a knife.

What are 5 Facts about alkali metals?

What are the similar properties of alkali metals?

  • They are shiny, soft, metals.
  • They are very reactive.
  • They all have one valence electron in the outermost shell which they seek to lose in order to have a full outer shell.
  • They are soft enough to be cut with a knife.
  • When exposed to air, they tarnish due to oxidation.

How many elements are in the alkaline earth metals family?

six chemical
The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
