Ra * Atomic radius increases as you go down the Group. Notice that beryllium has a particularly small atom compared with the rest of the Group. * Are very chemically reactive (give up 2 electrons during reactions) and are never found free in nature (same as alkali metals) * These metals form many compounds. They have ions with a +2 charge. Their atoms are smaller than those of the alkali metals. * found in the Earth's crust * they are so reactive * though radium is not always considered an alkaline on earth due to its radioactivity * The alkaline earth metals are silvery colored, soft, low-density metals, though are a bit harder than the alkali metals * two valence electrons and tend to lose both to form ions with a two plus charge * Berylium is the least metallic element in the group and tends form covalent bonds in its compounds. * These metals are less active than the alkali metals, but are still fairly active * react readily with halogens to form ionic salts * can react slowly with water. Magnesium reacts only with steam and calcium with hot water * Beryllium is an exception: It does not react with water or steam, and its halides are covalent The alkaline earth metals are named after their oxides, the alkaline earths, whose old-fashioned names were beryllia, magnesia, lime, strontia and baryta. These were named alkaline earthsbecause of their intermediate nature between the alkalis (oxides of the alkali metals) and the rare earths (oxides of rare earth metals). The classification of some apparently inert substances as 'earths' is millennia old

Which can be found on a periodic table elements compounds or mixtures?
Elements are found on periodic table. Compounds are not present on periodic table. The table does not contains mixture.Elements can be found on a periodic table. Compounds can be made by bonding two or more elements. But they are not depicted on the periodic table.
Are group 12 on the periodic table lanthandies or actinides?
No. There are two rows at the bottom of the periodic table. the first row elements are called lanthanides and the second row elements are called actinides.
What are the only two elements on the periodic table that's a liquid?
The two elements in periodic table which are liquid are: 1 mercury 2 bromine
What is the number of valence electron for all the elements in periodic table group 2A 2?
Two valence electrons.
What is H2S on the periodic table?
You will not find H2S on the periodic table. The periodic table contains only elements, and H2S is a compound, made of two elements, hydrogen (H) and sulfur (S).
What group on the periodic table gains two electrons?
Group 16 elements.

No. There are two rows at the bottom of the periodic table. the first row elements are called lanthanides and the second row elements are called actinides.
What name is given to group two in the periodic table?
Group-2 elements are alkaline earth metals. They are basic in nature.
What are the only two elements on the periodic table that's a liquid?
The two elements in periodic table which are liquid are: 1 mercury 2 bromine
What row is ammonium on the periodic table?
The periodic table is only for elements while Ammonium is a compound radical or ion NH4+ it is combination of two elements nitrogen and hydrogen these two are in periodic table.
What group in the periodic table has two valence electrons in their atoms?
The alkaline earth group has two valence electrons.
Is group 2 on the periodic table all metals?
Yes, group two elements are all called alkaline earth metals.
What is in the main group of elements?
The main group of elements includes all the elements in columns 1, 2, and 13 through 18 of a wide form periodic table. All the other elements are "transition elements", and those in the two horizontal rows at the bottom of a wide form periodic table are also called "inner transition" elements.
What is the number of valence electron for all the elements in periodic table group 2A 2?
Two valence electrons.
Which colume of the periodic table is called the alkalis?
There are two columns (groups) on the Periodic Table that contain the word 'Alkali'. They are the first and second groups. The first group is the Alkali Metals. This group contains the elements Li, Na, K, Rb, Cs, Fr. The second group on the Periodic Table is the Alkaline Earth Metals. This group contains the elements Be, Mg, Ca, Sr, Ba, Ra.
What is H2S on the periodic table?
You will not find H2S on the periodic table. The periodic table contains only elements, and H2S is a compound, made of two elements, hydrogen (H) and sulfur (S).
