Question

which of these statements correctly describe the atom? check all that apply.
all matter on earth is made up of atoms.
the subatomic particles of an element retain the properties of that element.
the neutron has no charge and identifies the element.
the electron is negatively charged and is located in a cloud surrounding the nucle
the proton is positively charged and is found in the nucleus.

Explanation:

• All matter (including that on Earth) is composed of atoms, so this statement is correct.
• Subatomic particles (protons, neutrons, electrons) do not have the properties of the element; only the entire atom does, so this statement is incorrect.
• Neutrons have no charge, but the number of protons (not neutrons) identifies an element, so this statement is incorrect.
• Electrons are negatively charged and occupy the electron cloud surrounding the atomic nucleus, so this statement is correct.
• Protons are positively charged and are located within the atomic nucleus, so this statement is correct.

Answer:

A. All matter on Earth is made up of atoms.
D. The electron is negatively charged and is located in a cloud surrounding the nucleus.
E. The proton is positively charged and is found in the nucleus.
