Question

Which of the following statements is most accurate regarding atoms?

A.Most atoms cannot combine with other atoms.
B. Chemical reactions divide atoms into smaller units.
C. Atoms of the same element may have different mass numbers.
D. Atoms only contain protons.

Answer 1

Atoms of the same element may have different mass numbers due to the presence of isotopes. isotopes with mass numbers 35 and 37. This means that even though they have the same number of protons and electrons, the isotopes have different numbers of neutrons. Therefore, option C is the most accurate statement regarding atoms.

Step-by-step explanation:

Atoms of the same element may have different mass numbers. For example, chlorine has two isotopes with mass numbers 35 and 37. This means that even though they have the same number of protons and electrons, the isotopes have different numbers of neutrons. Therefore, option C is the most accurate statement regarding atoms.
