In the context of the classification of matter, how are atoms combined in a mixture?
A
Atoms are physically combined without forming chemical bonds.
B
Atoms are arranged in a fixed, repeating pattern.
C
Atoms are separated by chemical reactions.
D
Atoms are chemically bonded to form new substances.
Verified step by step guidance1
Understand the difference between mixtures and pure substances: mixtures consist of two or more substances physically combined, while pure substances have chemically bonded atoms.
Recall that in mixtures, the components retain their individual properties and are not chemically bonded; instead, they are combined physically.
Recognize that atoms in mixtures do not form new chemical bonds; they remain separate entities mixed together.
Contrast this with compounds, where atoms are chemically bonded to form new substances with fixed ratios and properties.
Conclude that in mixtures, atoms are physically combined without forming chemical bonds, which allows the mixture to be separated by physical means.
