They react with water like the alkaline metal but does not change or melt with fire.
The alkaline part of the name comes from the fact that these metal form alkaline solutions, when they react with water. The earth part was added to differentiate these from the group one metals. Alchemists called them earth metals because they though that their oxides were new elements.
In the middle age the oxides of these metals (metals which are not known in time) are called alkaline earths: alkalinebecause these oxides react with water forming an alkaline solution and earths because in the past non-metallic compounds were called earths.
What else can I help you with?
Which of these groups of metals is the most active alkaline earth alkali halogen coinage?
The alkali group of metals is the most active.
What kind of bond does a halogen and an alkaline earth metal make?
alkaline earth metal forms a +2 cation and halogen forms a -1 anion alkaline earth metal is a metal and halogens are non metals therefore the bond between them is ionic
Where are the alkali and alkaline earth metals located on the periodic table?
Alkali metals: Group 1 in the periodic table Alkaline earth metals: Group 2 Halogens: Group 17 Noble Gases: Group 18 You can easily find them if you look at a periodic table.
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
The alkaline earth metals are found in group?
The alkaline earth metals are in the group 2 of the periodic table of Mendeleev.
What are the 5 named groups from the periodic table?
The five named groups from the periodic table are the alkali metals, alkaline earth metals, halogens, noble gases, and transition metals. Each group has unique properties and characteristics based on their electron configurations.
What are all the elements in the groups often called?
in periodic table،there are many groups of elements. group 1 is called alkaly metals . Group 2 is called alkaline earth metal.
What are elements in group 1a to 8a called?
Sometimes these are called the "representative" elements.
What is the most reactive group of a metals and nonmetals?
Metals: alkaline metals Nonmetals: halogens
What are element groups 1 and 7 called?
Element group 1 is called the alkali metals, while element group 7 is called the halogens.
What characteristic does the alkali metals alkaline earth metals and the halogens have in common?
All alkali metals, alkaline earth metals, and halogens have a common valence electron configuration: alkali metals have 1 valence electron, alkaline earth metals have 2 valence electrons, and halogens have 7 valence electrons. This shared electron configuration influences their chemical properties, such as reactivity and bonding tendencies.
What are the elements in the tall columns of the periodic table called?
Representative elements
How are halogens represented in a chemical reaction?
halogens are represented the same way as alkaline metals, you can use subscripts
The vertical columns on the periodic table are called groups or what elsecan they be called?
Not all, but some Groups/Vertical columns have their own name. Group (I) ; Alkali Metals. Group(II) ; Alkaline Earth Metals. Group(VII) ; The Halogens Group (VIII) ; The Noble or Inert Gases.
What are the specific names of the groups of elements found in groups 127 and 8 respectively?
group 1 are the alkali metals group 2 are the alkaline earth metals group 7 are the halogens group 8 are the noble gases
How do you ust the periodic table to identify alkali metals alkaline earth metals transition metals halogens and noble gases?
You can identify alkali metals in Group 1, alkaline earth metals in Group 2, transition metals in Groups 3-12, halogens in Group 17, and noble gases in Group 18 on the periodic table. Each group has characteristic properties that define them, such as valence electrons and reactivity, which can help in their identification.
What are examples of families in the periodic table?
The alkali metals, the alkaline earth metals, the transition metals, metalloids, nonmetals, including the halogens and the Nobel gasses.A simplified list including general groups and families of elements.
