which is a characteristic of atoms?\n○ they come in ten major types.\n○ they are the smallest units of matter.\n○ they can be found in nonliving things only.\n○ they cannot combine together.

Answer

Brief Explanations:

To determine the correct characteristic of atoms, we analyze each option:

  • "They come in ten major types": Incorrect, as there are over 100 known elements (types of atoms).
  • "They are the smallest units of matter": Correct, as atoms are the basic building blocks of matter that retain the properties of an element.
  • "They can be found in nonliving things only": Incorrect, as atoms are present in all matter, including living organisms.
  • "They cannot combine together": Incorrect, as atoms form molecules and compounds by combining through chemical bonds.

Answer:

B. They are the smallest units of matter.
