Concept explainers
Interpretation:
Why the atom is neutral as a whole has to be chosen from the given options.
Concept Introduction:
Atoms are made up of even smaller particles. These particles are very small and these are all the building blocks of atoms and they are known as subatomic particles. Protons, electrons, and neutrons are the subatomic particles that are found in atom. Electrons possess a negative electrical charge. Protons possess a positive electrical charge. Neutrons possess no charge and they are neutral.
If the mass is considered to one unit based on one electron, then the relative mass of a proton is equal to 1837 electrons and neutron is equal to 1839 electrons. Neutron is slightly higher in mass than that of a proton.

- Learning Goal: Atoms with the same number of protons but different numbers of neutrons are called isotopes. Some elements only have one naturally occurring isotope, while others such as carbon have two or more. In a naturally occurring sample, isotopes of each element are present in a certain percentage amount called the percent natural abundance. The mass number of an isotope is the sum of the number of protons and the number of neutrons for a particular isotope and is symbolized by A. A = number of protons + number of neutrons There are several different types of isotope notation. For example, a carbon isotope that has an atomic number of 6 and a mass number of 13 could be symbolized in any of the following ways: 13C, carbon-13, or C-13. b lock Part A Enter the appropriate symbol for an isotope of potassium-39 corresponding to the isotope notation X.
