They are similar.
Calcium and barium have different reactivities. Barium is more reactive than calcium because it has a greater tendency to lose electrons and form positive ions in chemical reactions. Calcium is a moderately reactive metal that readily forms compounds with oxygen and water, but it is not as reactive as barium.
Calcium and barium have similar reactivities, because they are both alkaline earth metals. Quantitatively, barium is slightly more reactive than calcium because it has more electron shells between its valence electrons and its nucleus.
They have "ium" in their name.
Barium is the alkaline earth metal known for its use in flares and fireworks due to its vibrant green color when burned. Barium salts, like barium nitrate or barium chloride, are commonly used as colorants in pyrotechnics to produce different hues of light.
Fluorine is an element and barium is also an element. There is no fluorine in barium and not barium in fluorine.
Barium is smaller than caesium. Different elements have different atomic radii, with caesium having a larger atomic radius compared to barium.
Barium is a soft, silvery metal that is malleable. It can be easily shaped and molded into different forms without breaking.
These are all properties of minerals, and barium is an element which does not occur in a pure (native) form in the earth. Different minerals with barium as a constituent have various different properties.
Calcium (Ca) and Barium (Ba) are different elements. They are in the same group on the periodic table, Group 2 (Alkaline Earth Metals), so they share some physical and chemical properties due to similar electron configurations, but they have different atomic numbers and distinct characteristics.
Atoms in the same group as calcium in the periodic table, such as strontium and barium, have similar chemical properties due to having the same number of valence electrons. These elements exhibit comparable reactivity and bonding patterns to calcium.
The thermal conductivity of Barium is expressed by the formula :18.4 W·m−1·K−1, So, yes, the chemical element, Barium conducts heat. However, compounds of Barium may have different degrees of thermal conductivity.
Strontium shares more properties with barium, as they are both members of Group 2 (alkaline earth metals) in the periodic table. These elements have similar chemical properties due to their position in the same group. Yttrium, on the other hand, belongs to a different group (Group 3) and therefore has different properties compared to strontium.
