Absolutely; barium is a highly reactive metal.
Yes, in the reaction between barium and oxygen to form an ionic compound, barium atoms will lose 2 electrons to form a Barium cation with a 2+ charge. Oxygen will gain those 2 electrons to form an oxide anion with a 2- charge.
If all the magnesium atoms are going to react, they will each need to combine with two oxygen atoms to form magnesium oxide. Therefore, for 100 magnesium atoms, you would need 200 oxygen atoms, which is equivalent to 100 oxygen molecules.
Two atoms of iron are needed to completely react with three molecules of oxygen to form two molecules of iron(III) oxide (Fe2O3). Each iron atom will lose three electrons to form Fe3+ ions, while each oxygen molecule will gain two electrons to form O2- ions.
'atoms' cannot 'react' to air pressure for air pressure is generated from atoms (oxygen, noble gasses, water).
No. A substance will not react with itself.
Oxygen is an element - the only thing that composes oxygen are oxygen atoms. Oxygen found naturally (molecular oxygen) is formed from two atoms of oxygen, O2.
Ionic bond occurs when calcium atoms react with oxygen atoms. Calcium donates two electrons to oxygen to form Ca2+ ions and O2- ions, resulting in an attraction between the oppositely charged ions.
Barium don't react with copper.
Water does not need to react with oxygen to make water!
If 8 atoms of iron react with 6 molecules of oxygen, they will form 4 units of iron oxide (Fe2O3) because each molecule of iron oxide contains 2 atoms of iron and 3 atoms of oxygen.
Barium is not considered flammable; however, when finely divided or in powder form, it can react with water or oxygen to produce flammable hydrogen gas. It is important to handle all forms of barium with caution to prevent any potential hazards.
