The alkaline metal with three rings would be magnesium(Mg). It has an atomic number of 12 and Atomic Mass if rounded is 24. Protons and eletrons are 12 (Electrons are always the same number as protons and the number of protons is the same as the atomic number)and Neutrons( found out by subtracting the atomic mass from the number of protons) is 12.
It would have 3 rings because there are 12 electrons. So, 2 electrons can be in the first orbit, 8 in the second, and 8 in the third. Basically you must fill up the first and second orbit and then in the third you have only 2.

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.
An alkaline earth hydroxide?
The generic formula for an alkaline earth hydroxide is M(OH)2
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
What is the general formula for alkaline earth metal hydride?
MH2, M= alkaline earth metal.
Alkali metal and alkaline earth metal have how many ionization energies?
Alkali metals (group 1 elements) have one valence electron. Hence have one ionization energy Alkaline earth metals (group 2 elements) have two valence electron. Hence have two ionization energy
What element has 2 valence electrons and 4 energy levels?
Well, honey, that element you're looking for is calcium. It's got 2 valence electrons and 4 energy levels, making it quite the popular choice for chemical bonding. So, there you have it, calcium is your guy in this electron game.
What alkali earth metal has electrons in exactly three energy levels?
Calcium is the alkaline earth metal that has electrons in exactly three energy levels. Its electron configuration is [Ar] 4s2, and it has two electrons in the 4s orbital and a total of three energy levels.
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.
How many valence electrons does alkaline earth metal have?
2
What elements has 2 main energy levels and seven valence electrons?
Alkaline earth elements have two valence electrons Those are the alkaline earth metals, technically referred to as Group 2. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). Radium has two valence electrons and is in Group 2, but is sometimes left off lists of the alkaline earth metals because it is radioactive. - Soccer_Fanatic18
Is the ionization energy of alkali metals larger or smaller than the alkaline earth metals in the same period?
It is about first ionization energy. It is less than alkaline earth metals.
Which element is an alkaline Earth metal with 2 electrons an the second level?
The element you are referring to is beryllium (Be). Beryllium is an alkaline Earth metal that has two electrons in the second energy level.
What is the name for metals with two electrons in the outer energy level?
They are called Alkaline Earth Metals
Why does alkaline earth metals have two outer electrons in its outer energy level?
Cause they W
What is the family name that calcium is in?
Group 2 (alkaline earth metals): lithium, sodium, potassium, caesium, rubidium, francium.
Alkaline-earth metal do not react with oxygen?
Alkaline-earth metals do react with oxygen, forming oxides. The reaction tends to be less vigorous compared to alkali metals, as alkaline-earth metals have a higher ionization energy. Examples of alkaline-earth metal oxides include magnesium oxide (MgO) and calcium oxide (CaO).
Which are products of the alkaline and earth alkaline metals combustion?
Alkaline metals and alkaline earth metals form their oxides when burnt. These oxides are base.
