What element does the element calcium belong to?
Calcium belongs to the group 2 of the periodic table, the alkaline earth metals.
Which alkaline earth metal has the lowest atomic number?
Beryllium has the lowest atomic number among the alkaline earth metals.
Is alkali the only earth metal?
No, alkali metals are not the only earth metals. Earth metals include both alkali metals and alkaline earth metals. Alkaline earth metals are a group of elements in the periodic table that are chemically similar to, but less reactive than, alkali metals. Examples of alkaline earth metals include magnesium, calcium, and barium.
Which 2 groups of metals are the most reactive?
Alkali metals (Group 1) and alkaline earth metals (Group 2) are the most reactive groups of metals. They readily lose electrons to form ions and participate in chemical reactions with nonmetals to achieve a stable electron configuration.
How do you use combining ratios to distinguish the alkali metals from the alkaline earth metals?
Alkali metals have a +1 oxidation state and form compounds with a 1:1 ratio of metal to other element, while alkaline earth metals have a +2 oxidation state and form compounds with a 1:2 ratio. By analyzing the stoichiometry of compounds formed with these metals, you can distinguish between alkali metals and alkaline earth metals.
Which element is used in aerospace industries in alloys with other metals?
Titanium is commonly used in aerospace industries to manufacture alloys with other metals due to its strength, lightweight properties, and resistance to high temperatures.
Which family is the element Radium in?
Radium is in the alkaline earth metals.
What element has 2 valence electrons and is in period 3 and is a metal?
The element that has 2 valence electrons, is in period 3, and is a metal is magnesium (Mg). It is located in Group 2 of the periodic table, which is known as the alkaline earth metals. Magnesium is known for its lightweight properties and is commonly used in various applications, including aerospace and automotive industries.
Is Be a compound or an element?
Beryllium (Be) is an element. It is part of the alkaline earth metals.
What is the group of element that are less reactive?
alkaline earth metals
Which choice has the element groups in the correct order from left to right on the periodic table?
Alkali metals, alkaline earth metals, transition metals
What element family radium belong too?
alkaline earth metals
What element is the first member of the alkaline earth metal?
Alkaline earth metals are in the second group. Be is the first metal of them.
What element does the element calcium belong to?
Calcium belongs to the group 2 of the periodic table, the alkaline earth metals.
Which choice has the element groups in the order from left to right on the periodic table?
Alkali metals, alkaline earth metals, transition metals
Is the element Se an alkaline earth metal?
No. Selenium is a chalcogen. The alkaline earth metals are those in the same column as calcium.
What is the most reactive element family?
the alkaline metals they are on the far left side of the table
