Are Alkali metal hydroxides and alkaline earth metal hydroxides strong metals?
Alkali metals are metals in Group I (far left column) such as Lithium, Sodium, Potassium, etc. They have a valence of -1.Alkali Earth Metals are in Group II (second column from the left) such as Berylium, Magnesium, Calcium, etc. and have a valence of -2.One Hydroxide (OH-) ion will form an ionic bond with group 1 elements {Like NaOH }, and two Hydroxide ions will form an ionic bond with group 2 elements {like Ca(OH)2 }
What are some facts about alkaline earth metals?
Alkaline Earth Metal found in second group of periodic table. The components are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). Below some characteristics of Alkaline Earth metals, 1. These metals have an oxidation number of +2 that makes them very reactive. 2. These elements are not freely in nature. 3. These elements are found on earth crust but not in their basic form. 4. they have couple of electrons in their outer most shell. 5. They are distributed in rock structures. 6. They have a high boiling and melting point. 7. they have low density, electron affinity and electromagnetic. 8. they are silver in color. 9. ductile and malleable. 10. Easily reactive with halogens and water.
What consists of positivley charged metal ions embedded in a sea of valence electrons?
metallic bond
What characteristics are shared by all alkali metals and alkaline earth metals?
Well, isn't that just lovely? Alkali metals and alkaline earth metals are both very friendly groups on the periodic table. They love to make new friends by giving away their outer electrons, which makes them very reactive and eager to bond with other elements. So, you see, they share this wonderful quality of being very sociable and forming strong relationships with other elements.
How do you join metal using solder?
In order to bond a porous surface (wood) to a non-porous surface (metal) you will need an epoxy. Often an epoxy comes in 2 parts, the resin and the hardener, when mixed together they form the bond. Be careful though, once the bond is set you won't be able to get them apart.

Why is the alkali metal more reactive that an alkaline earth metal?
the alkali metals have one valence electron, or one electron available to bond with another particle. this lets them bond easily with, lets say, a halogen, which has one 'slot' for an electron. two atoms of an alkali metal would be able to bond with a chalcogen, and so on. it's really all in the number of electrons. the alkaline earth metals have two valence electrons, so they would bond less easily with other elements.
What bond will occur between metal and halogen?
A metallic-halogen bond will typically involve the transfer of electrons from the metal to the halogen, resulting in the formation of an ionic bond. The metal loses electron(s) to become a cation, while the halogen gains electron(s) to become an anion, leading to the attraction between the oppositely charged ions.
Is Kl a ionic covalent or both?
Kl (potassium iodide) is an ionic compound because it is composed of a metal (potassium) and a non-metal (iodine) that form an ionic bond due to the transfer of electrons from the metal to the non-metal.
What are the example of single bonds?
F-F Cl-Cl or any other halogen-halogen ;halogen- alkaline metal Na-Cl
An active metal and halogen react to form a?
A metal and halogen react to form an ionic bond in which the metal gives an eletron to the halogen Most basic example would be table salt NaCl NaOH + HCl = NaCl + H20
What kind of chemical bond is formed by transfer of electrons between alkali metal and halogen?
ionic bond
Why does the halogen group usually make ionic bonds?
easier to gain electron from alkali metal than sharing with non-metal for covalent bond
Which element can combine with two halogens in an ionic bond?
any alkaline earth metals
What is the name of the compound ionic bond of calcium and fluorine?
CaF2, Calcium Fluoride. It is useful in iron smelting
What is the ionic compound of beryllium and chlorine?
We know that the alkaline earth metal beryllium (Be) and the halogen chlorine (Cl) form the ionic compound beryllium chloride (BeCl2). The equation might look like this:Be + Cl2 => BeCl2
Does strontium chloride have a ionic or covalent bond?
It is ionic as are all strontium compounds.
What is one of the metals that can use the inner shell before using the outer shell to bond?
Copper is an example of a metal that can use its inner shell before outer shell electrons to bond. It has a configuration of 3d104s1, and the 4s electrons are used before the 3d electrons in bonding reactions.
