How many electrons do alkaline earth metals have?
Each has 2 valence electrons but the number of total electrons varies with each metal. Here they are for each metal. Beryllium: 4 Magnesium: 12 Calcium: 20 Strontium: 38 Barium: 56 Radium: 88.
What is the oxidation number in Alkaline Earth Metals?
The oxidation number of alkaline earth metals is typically +2. This is because they have two valence electrons, which they tend to lose to achieve a stable electron configuration.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
Do all alkaline metals have 2 electron shells?
No. All the alkaline earth metals have 2 valence electrons, meaning they have two electrons in the outermost shells. No two alkaline earth metals have the same number of electron shells. Beryllium is the only one with two shells.
What is the number of valence electrons for Alkali Earth Metals?
Alkali Earth metals have a single valence electron, and are found in the first group.
How many valence electrons are in aluminum?
Alkaline earth metals are group 2 elements and have 2 valence electrons.

+2
Which element has two valence electrons?
Zinc and Calcium
What is the number of valence electrons in strontium?
Strontium has 2 valence electrons because it is part of the Alkaline Earth Metals or Group 2 of the periodic table which all have 2 valence electrons
Do transition have higher melting point than alkaline and alkali metals?
Yes, transition metals generally have higher melting points compared to alkaline and alkali metals. This is because transition metals have a greater number of valence electrons and a stronger metallic bond, which requires more energy to break and transition from solid to liquid. In contrast, alkaline and alkali metals have fewer valence electrons and weaker metallic bonds, resulting in lower melting points.

How do you use the periodic table to recall the ionic charge of alkali metal an alkaline earth metal or aluminum?
The ionic charge depends on the number of valence electrons. Alkali metals, alkaline earth metals and aluminium have 1, 2 and 3 valence electrons respectively and will hence form ions with +1, +2 and +3 charges respectively.
