a compound a a number of small spherical shapes upon thin cylindrical shaped connectors. the spherical shapes, can only be two or more different colours, any less than that, and it would be an element.
When compounds are formed, they can look like a variety of things depending on their chemical composition. Some compounds may appear as solid crystals, while others may be liquids or gases. The physical appearance of a compound is determined by the arrangement of its atoms and the forces between them.
Compounds containing iron and copper do not typically resemble the pure elements in their metallic form. When combined in compounds, the properties and appearance of the elements change due to their chemical bonding with other elements.
Like dissolves like. Water is polar solvent and hence it dissolves ionic and polar compounds.
krypton will form compounds like KrF2. Xenon will form compounds like XeF4, XeF6 etc.
generally ionic compounds like those compounds which dissolves into ions in water like NaCl,NaOH etc.
gas exchange in the lungs is progressively impaired by the accumulation of phospholipids, compounds widely found in other living cells of the body.
Organic chemistry is sometimes called carbon compounds chemistry because all of the compounds you look at contain carbon.
Negative (such as -2 in compounds like O2 or Cl-) or positive (such as +3 in compounds like NCl3), depending on the element and the compounds involved.
In general, "Like dissolves like". So organic compounds will dissolve in organic solvents
compounds ae used in science , they are next to elemements and also they are te best thing ever because the thing is that if they was doinga experiement they would have to look at the diffrent compounds and the diffrent elements
Fluorine can form compounds with every element except Helium. Many compounds with the noble gases (such as neon fluoride) are pretty unstable and most are very reactive, but they can be formed.
Europium is a shiny, silvery metal that is relatively soft and easily oxidized in air. It is a lanthanide element that is typically found in compounds rather than in its pure form. Europium is used in the production of red phosphors for television and computer screens.
