What is the first element in the alkaline earth metal group?
Beryllium
The name Beryllium comes from the Greek beryllos which is the name for the gemstone beryl. The element is a high-melting, silver-white metal which is the first member of the alkaline earth metals. It is not abundant in the environment and occurs mainly in the mineral beryl with aluminum and silicon.
What is the Group 1 element called?
the alkali metals
The Group 1 elements are called the alkali metals. They are placed in the vertical column on the left-hand side of the periodic table . All the Group 1 elements are very reactive .
Which member of the alkaline earth metals family has?
Who’s in the family? The members of the alkaline earth metals include: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). As with all families, these elements share traits. While not as reactive as the alkali metals, this family knows how to make bonds very easily.
Which of the following are alkaline earth metals?
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).
What element is a member of the alkaline earth metals used to make fireworks and medicines?
MAGNESIUM – I am a member of the alkaline earth metals used to make fireworks and medicines.
Why is alkaline earth metal used in fireworks?
A fuse ignites gunpowder, which explodes. Fireworks also contain small amounts of alkaline Earth metals, such as magnesium, calcium, barium, or strontium. These metals get really hot when the fireworks explode and glow in brilliant colors.
What group do alkaline earth metals belong to?
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).
Why are the group 1 metals called the alkali metals?
Why are they called the alkali metals? The alkali metals are so named because when they react with water they form alkalies. Alkalies are hydroxide compounds of these elements, such as sodium hydroxide and potassium hydroxide.
What are the Group 1 elements used for?
alkali metalAny of the soft, light, reactive metals of Group 1 of the periodic table; lithium, sodium, potassium, rubidium, cesium, and francium. lyeA strong caustic alkaline solution of potassium or sodium salts, obtained by leaching wood ashes. It is much used in making soap as well as in biodiesel.
Which member of the alkaline earth metals family has elements showing diagonal relation with Li?
List four properties to show the diagonal relationship between lithium and magnesium. The similarity between Li and Mg is because of their similar atomic radii (Li = 152 pm; Mg = 160 pm) and ionic radii. (Li+ = 76 pm, Mg2+ = 72 pm).
Which is an alkaline earth metal in Group 2?
Radium (atomic number 88) has similar properties to barium and is also in the Group 2 category. However, radium is a radioactive element and is generally under the category of radioisotopes in addition to being an alkaline earth metal, because it is not a stable element. The Group 2 elements tend to be less reactive than their Group 1 counterparts.
What are the alkaline elements on the periodic table?
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).
Which is more reactive beryllium or alkaline earth metals?
Many beryllium compounds are toxic, but these materials have been employed in metal alloys. The alkaline earth elements are in Group 2 of the periodic table. These elements each have two s electrons in their outer shell. The alkaline earth elements are less reactive than the alkali metals.
Is the element radium an alkaline earth metal?
However, radium is a radioactive element and is generally under the category of radioisotopes in addition to being an alkaline earth metal, because it is not a stable element. The Group 2 elements tend to be less reactive than their Group 1 counterparts.
