Magnesium has the atomic number 12, barium has the atomic number 56.
The density of magnesium is 1,78 g/cm3, the density of barium is 3,51 g/cm3.
Mg does not react with cold water while Ca, Sr, and Ba react with cold water to form metal hydroxide and hydrogen gas.
Group 2 metals (Be, Mg, Ca, Sr, Ba, Rn) have two electrons in their valence shell.
Examples: Ca, Mg, Ba, Sr, Ra, etc.
Ne (Highest First Ionization Energy) C Be Mg Sr (Lowest First Ionization Energy)
Barium doesnot form compound with magnesium. Both are in the same group and are metals. The symbol for barium is Ba and that of magnesium is Mg.
ba ecnomices syllabus in MG ?
Mg (magnesium) has the lowest electronegativity among Ba, Ca, Mg, and Sr.
i am doing ba sociciology in mg .so i requested to know the dates of exams
Ba has a larger atomic radius than Mg because Ba has more energy levels and electrons than Mg, leading to increased electron-electron repulsion which pushes the outer electrons further apart. This results in a larger atomic radius for Ba compared to Mg.
1 mg is lighter.
Mg does not react with cold water while Ca, Sr, and Ba react with cold water to form metal hydroxide and hydrogen gas.
Be, Mg, Ca, Sr, Ba, and Ra all belong to the family Alkaline Earth Metals
Be, Mg, Ca, Sr, Ba, Ra
yes
Be, Mg, Ca, Sr, Ba, Ra
Be,Ca,Sr,Ba are in the same group as Mg. They all are metals
Assuming you have given a complete equation, no. It requires oxygen as a reactant and will always have CO2 and H2O as products. Plus, combustion reactions typically involve carbon based elements as reactants.
