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
What is the general formula for alkaline earth metal hydride?
MH2, M= alkaline earth metal.
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
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?
The element magnesium has four electron energy levels and two electrons in its outer energy level in the neutral atom. Use the link to Wikipedia for more details.
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.
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.
Elements in group 2 are called?
Group 2 elements in the periodic table are the alkaline earth metals.
What is group 2A elements known as?
Alkaline Earth Metals
What is the name for metals with two electrons in the outer energy level?

Is Strontium Sr Alkali Alkaline-earth or transition?
Sr is in group 2. It is an alkaline earth metal.
What is the family name that calcium is in?
Group 2 (alkaline earth metals): lithium, sodium, potassium, caesium, rubidium, francium.
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.
