GCSE CHEMISTRY - What are the Alkaline Earth Metals

The alkaline earth metals are less reactive than the alkali metals. Calcium and magnesium are fourth and fifth in the reactivity series. 3. The alkaline earth metals have the common properties of metals, are silvery-grey in colour and good conductors of heat and electricity. 4. The alkaline earth metals are harder than the alkali metals and it

Beryllium, Calcium and Magnesium: Properties, Uses

Group 2 elements are referred to as “ alkaline earth ” metals (tan column below). The name “ alkaline ” comes from the fact that compounds of these elements form basic (pH greater than 7) or alkaline solutions when dissolved in water. If the Group 1 elements all have one electron in their outer orbital, we can predict that the Group 2 elements will have two electrons in that outer shell.

Characteristics of the Compounds of the Alkali Earth Metals

Their melting and boiling points are higher compared to the alkali metals. These metals are strongly electropositive in nature. Alkaline earth metals give different colour with the flame test such as calcium gives brick red colour, strontium gives crimson colour and barium gives apple green colour, all of which are different for different metals.

Information on Alkali Metals – Stanford Environmental

Information on Alkali Metals. Print. In their pure forms, the alkali metals (lithium, sodium, potassium, rubidium, and cesium) are soft, shiny metals with low melting points. Alkali metals react readily with air and moisture. Due to their reactivity, special precautions must be taken when using and storing these metals.

Oct 16, 2011· Alkali vs Alkaline Generally, alkali is used to indie bases. It is used as a noun and alkaline is used as an adjective. However, in this context, they are used to indie group 1 and group 2 metals in the periodic table. However, when they are used to indie elements, normally alkali metal …

The Alkaline Earth Metals (Group 2)

Four of the six group 2 elements—magnesium (Mg), calcium (Ca), strontium (Sr), and barium (Ba)—were first isolated in the early 19th century by Sir Humphry Davy, using a technique similar to the one he used to obtain the first alkali metals. In contrast to the alkali metals, however, compounds of the alkaline earth metals had been

Why doesn''t EDTA complex with alkali metal ions?

Alkali metals will tend to form ionic salts with EDTA. Personally, I agree with the other comments. EDTA does form complexes with alkali metals. I''d classify the disodium salt of EDTA as a complex. It has a metal and an organic ligand, and there''s no direct metal …

S Block Elements - Properties, Periodic Trends, Electronic

Alkali metals and its respective salts have the capability to impart colour to the oxidizing flame due to the heat generated from the flame which excites the valence electrons from one energy level to another energy level.
