Question

answer the questions below to fill out the chart in the image, keeping in mind that each question number has an associated place in the chart (which is shown)

Explanation:

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. In the case of the atoms in question 17, the two atoms have different mass numbers (which is the sum of protons and neutrons). Since they have the same atomic number (proton number, as indicated by the subscript in the \( _Z^A X \) notation, where \( Z \) is atomic number and \( A \) is mass number), they are the same element. But because their mass numbers (and thus neutron numbers, since \( \text{Number of neutrons}=A - Z \)) are different, they fit the definition of isotopes.

Answer:

Isotopes
