Question

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.

Explanation:

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. In a neutral atom, the number of electrons equals the number of protons, but ions can change the electron - count. Isotopes are atoms of the same element with different numbers of neutrons.

Answer:

• 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 protons.
• Atoms of the same element can be isotopes of that element.
