Answer

Explanation:

Step1: Recall element - defining property

The number of protons in an atom's nucleus defines the element.

Step2: Analyze proton numbers in table

Atom A has 6 protons, Atom B has 6 protons, Atom C has 7 protons, and Atom D has 7 protons.

Step3: Count distinct elements

Elements with 6 protons are one type, and elements with 7 protons are another type. So there are 2 distinct elements.

Answer:

2 (corresponding to the first option in the multiple - choice list)
