Alkaline Earths
The Alkaline Earth Metals are the second group of the periodic table of the elements. They are highly reactive and share many properties with each other. In this category, there are ANY questions that have to do with the alkaline earths, or their elements: Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.

What are the intermolecular forces in beryllium fluoride?
Disperson forces only because it is not a polar compound.
What is beryllium's electron affinity?
It is NOT negative (for the first IE). Because Be's configuration is 1s2 2s2, we observe that it has no vacant orbital to accommodate an electron, meaning that to insert an electron, it has to go into a new sub-orbital, the higher-energy 2p. Hence, you need energy to promote this electron to a 2p level to force Be to accept it.
Why do the alkaline earth metals react similarly?
All alkali earth metals have two valence electrons and they all form ions in +II oxidation state.
Is stomach ache medicine alkali?
Medicines given for gastritis are alkaline.They reduce acidity of stomach.
Answer:
The term "stomach ache" covers a wide range of potential medical problems which can cover over acidity, gas production cancer, polyps, alergies, poisons, mucous problems and other diseases.. Some can be treated with basic (alkaline solutions), some with acidic solutions, some with antibiotics, some by dilution and some by surgery. There is no way to determine the pH of all of these possible variations.
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.
Is washing up liquid a weak or strong alkali?
it is weak and strong because it neutralises acids. So its strong not weak but weak not strong.
What family contains beryllium uranium bromine argon?
Beryllium: alkaline earths family
Uranium: actinoids family
Bromine: halogens family
Argon: noble gas family
What are the side effects arsenic beryllium cadmium lead and zinc?
Go to the link and search MSDS for the wanted substance.

How did the alkaline earth metal get their name?
1. Their oxides are base (alkaline) forming with water.
2. The high amounts of the most common elements in this group, Mg and Ca, are found in rocky earth crust and sediments. (Eg. slack lime Ca(OH)2, carbonate rocks, magnesite).
Another explanation of 'earth' is this:
3. These oxides melt at such high temperature that they remain solids ("earths") in fires (Eg. burned lime CaO).
Added:
The alkaline earth metals are a series of elements comprising Group 2 (IUPAC style) (Group IIA) of the Periodic Table:
beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra).
Which alkaline earth metal is part of the reaction process of photosynthesis?
Magnesium is the alkaline earth metal that is part of the reaction process of photosynthesis.
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
What does beryllium and silicon make?
Lebeau reported in 1898 the preparation of a beryllium silicide but now this compound is very doubtful.
What are alkaline earth metals?
They are a series of elements, or metals, on the Periodic Table of Elements. The alkaline earth metals are: beryllium, magnesium, calcium, strontium, barium, and radium (i.e, the ones with two electrons in their outer shell and common oxidation state +2, right next to the alkali metals with common oxidation state +1). They're all silvery-colored and soft, and they combine with water to form alkaline hydroxides, but not as readily as the alkali metals do.
