Atoms of different elements recovered unchanged. Question 3. simplest, chemical substances - elements. It is important to note that, two atoms of the same element bonded in a molecule do not form a chemical compound, since a compound is a combination of two different elements. Explain the characteristics of the mixtures. The chemical formula lets you know what type of atoms make the substance and what ratios those atoms are found in. Mixtures, A mixture is a combination of two or more substances in which the substances do not bond. There are three correct examples for each category, with images. positive and negative ions (Na+Cl-), Exist as neutral Water is always conducts electricity, Remain as same molecule A common example of a mixture is air. Compounds are those substances which can be decomposed into constituent elements or can be synthesized out of constituent elements. The notation For example, carbon dioxide has a chemical formula of CO2, this means the compound is made of carbon and oxygen atoms at a ratio of 1 carbon to 2 oxygen. Say, “Now that we have talked about mixtures, what about the other category of matter? Learn vocabulary, terms, and more with flashcards, games, and other study tools.
