Most reactive alkaline earth metal?
Radium
What is an element with a single electron in its highest energy level is probably what type of metal?
An element with two electrons in its highest energy level is probably an alkaline earth metal. More specifically, it is likely magnesium or calcium, as these are the most common alkaline earth metals.
What element is the most alkaline?
Cesium is the most alkaline element on earth.
Which is most electronegative metal?
Gold, electronegativity: 2.4
What is the oxidation numbers of alkaline metals?
The question should be either 'alkali metals' or 'alkaline earth metals'. For alkali metals or group 1 elements, the oxidation number is +1 (note. hyddrogen can have +1 and -1). For alkaline earth metals, the oxidation number is +2 In addition all these elements will have an oxidation number of 0 in their elemental form
Which alkaline earth metal is the most likely to attract an electron pair?
The electronegativityÊ of alkaline earth metals decreases as you go down the group due to increase in atomic radius. The earth alkaline metals are beryllium, magnesium, strontium, barium and radium. Radium has the smallest electronegative.
Most reactive alkaline earth metal?
Radium
What is the alkali metal of calcium?
It is an Alkaline Earth Metal
Why is Potassium an Alkaline Earth Metal?
Potassium is not an alkaline earth metal, it is an alkali metal. The metals in the leftmost column of the periodic table. They are noted for their high reactivity and for the fact that most of their compounds are basic.
Is magnesium a non metal or metal?
metalIt is an alkaline earth metal and the eighth most abundant element in the earth's crust by mass
What is the most reactive alkaline earth metal?
Radium (Ra), atomic number 88, is the most reactive alkaline earth metal. It has the most energy levels of all the alkaline earth metals therefore it's electrons are more easily taken away.
Is sodium a halogen a noble gas a alkali metal or a alkaline earth metal element?
It is located, in the periodic table, with the metalloids. However, it is a transition metal.
Why Alkali metal and alkaline earth metal form cation?
alkaline earth metals and alkali metals have 2 and 1 electrons in their outer most shell and are not tightly bound to nucleus so they are ready to lose their outer most electrons to form mono and divalent cations.
What is the difference between alkaline metal and an earth alkaline metal?
They are both groups in the periodic table. Alkaline metals are group one. These are the least stable elements for e.g. Francium. Alkalie Earth Metals are group 2. The second most unstable elements. For e.g. Magnesium. Hope this helps!
Which member of alkaline earth metal is least reactive?
Look at any periodic table: Beryllium #4 Magnesium #12 Calcium #20 Strontium #38 Barium #56 Radium #88

What element is the most alkaline?
Cesium is the most alkaline element on earth.
