Elements contain only one type of atom (atoms with the same number of protons). Compounds contain more than one element, and thus contain atoms with different numbers of protons. Compounds can be converted into elements, but elements are not reducible to anything simpler (besides subatomic particles).
No. Elements, compounds and mixtures are 3 different terms.
Salts are chemical compounds not elements.
Compounds are combinations of elements. They are different from molecules in the fact that Compounds cannot be a combination of the same element ( O2 ) instead compounds are combinations of different elements ( CO2 )
properties of compounds are different than elements
Compounds are composed of two or more different elements that are chemically bonded together. These elements combine in fixed ratios to form specific compounds with unique chemical and physical properties.
No. The chemical formulas for the two compounds would be different as the ratios were different. For example there are three different oxides of iron which obviously contain the same two elements but these are in different ratios:- FeO Fe3O4 Fe2O3
Because the proportions of the elements are different in the different compounds. They may contain the same elements, but the different proportions make them different compounds with different properties.
Chemical compounds
When two or more different elements unite chemically, they form a compound. Compounds have a fixed chemical composition and distinctive properties different from the elements that make them up.
Molecules aren't different because they are the smallest part of a compound. Compounds are made up of multiple kinds of elements. So molecules are the elements that make up of the compounds.
Atoms of different elements can " stick together " ( making compounds ) via elements sharing or trading arrangements called
Common compounds made up of two different elements include water (H2O), carbon dioxide (CO2), and salt (NaCl). Each of these compounds consists of atoms from two different elements chemically bonded together.
