In old nomenclature, oxides of elements were called "earths". The oxides of Group II form alkaline (basic pH) solutions in water; i.e. they are base anhydrides. Thus they were referred to as the alkaline earth metals.
what dose the weather mean & what is it about & where and why do we have weather
Aboriginal does not really mean anything. The Aborigines are a people indigenous to Australia, they inhabited the land far before the white settlers moved there and are now a protected culture.

The Earth is more dense than Mars Mars mean density 3.9335 g/cm³ Earth mean density 5.515 g/cm3
Plate tectonics, rotation, and gravitational pull of the Sun, shift the Earth slightly, so that the Earth bulges near the Equator.
You mean valence electron? 2 If your talking about Bohr Diagrams then it depends on the metal
Alkali metals are in the first column of the periodic table, but do not include Hydrogen. The alkali metal family is composed of Lithium, Sodium, Potassium, Rubidium, Cesium and Francium. An example of an alkali metal is Sodium (Na).
Assuming "very reactive" to mean spontaneous and energetic in reaction, lower Alkaline metals are among the most reactive.
Non-alkali refers to substances or solutions that do not contain alkali metals, such as sodium, potassium, or lithium. These substances are typically neutral or acidic in nature, as opposed to alkaline. Non-alkali substances may include non-metal elements, non-alkaline earth metals, or organic compounds.
It is about alkaline metals. You can cut them using a knife.
Meta aluminates are compounds formed by the reaction between aluminum oxide (alumina) and chemical compounds such as alkalis or alkaline earth metals. They are commonly used as catalysts, adsorbents, and materials in various industrial applications.
A strong base is a chemical compound that can accept protons (H+) readily in a chemical reaction. It typically has a high pH value and will readily neutralize an acid. Strong bases are usually hydroxides of alkali metals or alkaline earth metals.
Do you mean Alkali Earth metals? If so they are the second column to the left of the chart.http://www.elementsdatabase.com/Images/periodic_table1.gif
The alkalinization is the extra increase in alkaline soil that causes destruction of the earth or the excess salt on the ground that causes no growth of plants here even grass.
Do you mean Strontium - it is an alkaline earth metal, soft silver white or yellowish
it means life or like earth our life
What does it mean when a persons alkaline phos level is at 40.0?
