Sample Response: I disagree with her because an atom has two main parts: the nucleus and the electron cloud. Atoms have three subatomic particles: protons, neutrons, and electrons. Which of these statements did you include in your answer? Check all that apply The two main parts of an atom are the nucleus and the electron cloud. The three subatomic particles of an atom are protons, neutrons, and electrons.

A and B

Explanation:

Both the given statements are true.

An atom has two main parts that include the nucleus and the electron cloud and an atom has three subatomic particles electron, proton and neutron.

The nucleus is consists of neutrons (neutral subatomic particles) and protons (positively charged) and the cloud of electrons consists of electrons which are negatively charged particles.

Hence, the correct answer is "A and B".

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
