which statements describe elements? check all that apply. atoms of the same element can have different numbers of protons. atoms of the same element always have the same number of electrons. atoms of the same element can have different numbers of neutrons. atoms of the same element always have the same number of neutrons. atoms of the same element always have the same number of protons. atoms of the same element can be isotopes of that element.

Answer

Explanation:

Step1: Recall element - proton relationship

The atomic number, which is determined by the number of protons, defines an element. So atoms of the same element always have the same number of protons. The statement "Atoms of the same element always have the same number of protons." is correct.

Step2: Recall electron - element relationship

In a neutral atom, the number of electrons equals the number of protons. But atoms can form ions by gaining or losing electrons. So atoms of the same element do not always have the same number of electrons. The statement "Atoms of the same element always have the same number of electrons." is incorrect.

Step3: Recall neutron - element relationship

Atoms of the same element can have different numbers of neutrons. These are called isotopes. So the statements "Atoms of the same element can have different numbers of neutrons." and "Atoms of the same element can be isotopes of that element." are correct, and "Atoms of the same element always have the same number of neutrons." is incorrect.

Step4: Recall basic proton - element fact

Atoms of the same element cannot have different numbers of protons as the number of protons defines the element. So the statement "Atoms of the same element can have different numbers of protons." is incorrect.

Answer:

Atoms of the same element always have the same number of protons. Atoms of the same element can have different numbers of neutrons. Atoms of the same element can be isotopes of that element.
