<p>Isotopes are atoms of the same element with different numbers of neutrons. They are calculated by subtracting the atomic number from the atomic mass number to determine the number of neutrons.</p> Signup and view all the answers

<p>Ions are formed when an atom gains or loses electrons, resulting in a net positive or negative charge. The number of protons and electrons in an ion determines its charge.</p> Signup and view all the answers

<p>Atomic masses are not whole numbers because they account for the presence of isotopes and their relative abundance in nature. The weighted average of the isotopic masses results in non-integer atomic masses.</p> Signup and view all the answers

<p>Atomic models such as Dalton's Billiard Ball Model, Thomson's Plum Pudding Model, and Rutherford's Nuclear Model differ in their depiction of the atom's structure and behavior. However, they all share the concept of an atomic nucleus containing protons and neutrons, with electrons orbiting around it.</p> Signup and view all the answers

<p>The atomic number represents the number of protons in an atom, which uniquely identifies the element. It is used to determine the identity of an element because each element has a distinct atomic number, defining its chemical properties and position in the periodic table.</p> Signup and view all the answers
