potassium
The generic formula for an alkaline earth hydroxide is M(OH)2
No. The alkali and alkaline earth metals are very reactive.
MH2, M= alkaline earth metal.
It is not a alkaline metal.It is a alkaline earth metal.
No. Scandium is in column 3 of a periodic table, and the alkaline earth metals are in column 2.
This chemical element is calcium (Ca).
Barium
Barium (Ba) has 56 protons. Barium is an alkaline earth metal.
Barium
calciumThe element sulfur's atomic number is 16, so there are 16 protons in its nucleus. The element bromine's atomic number is 35, and there are 35 protons it its nucleus. This means the element will have an atomic number between 16 and 35. Since the question asked which Group 2 element fits in that window, we can go to the periodic table and look down the column of Group 2 elements and find that calcium is the element so described. It has the atomic number 20, and that means 20 protons in its nucleus.Remember that the Groups on the periodic table of elements are the vertical columns, and they range from Group 1 to Group 18. Group 2 elements are the so-called Alkaine Earth metals. A link is provided to the Wikipedia post on the periodic table. Bookmark this one, kids! Each element on the table is a hyperlink to the Wikipedia post on that element. Even the Group numbers are hyperlinks to the post on that Group! It just doesn't get any better that that.
This chemical element is calcium.
The family name is 2A or IIA.(Answer Improvement) 2A is really the same thing as group 2 above in the question. The family name for this group is "alkaline earth metals".
No, the chemical properties of calcium and bromine are not similar. The melting point for Calcium is 8390C, bromine's is -7.250C. Calcium's boiling point is 1484°C, bromine's is 58.750C. etc. Calcium is a silvery white, soft alkaline earth metal. Although none of the alkaline earths occur free in nature, calcium compounds are abundant. Bromine is a reddish-brown liquid, and it has a metallic luster in solid form.
the yellow elements in the periodic table of elements indicate that these things are made by humans
Calcium. Calcium-40 isotope has 20 protons, 20 electrons and 20 neutrons.
Group 2 elements in the periodic table are the alkaline earth metals.
