The main difference between isotopes of the same element is the number of neutrons in the nucleus. Isotopes have the same number of protons and electrons but different numbers of neutrons, which affects their atomic mass.
Potassium's atomic number is 19, which means it has 19 protons. Since atoms are electrically neutral, it also has 19 electrons. To find the number of neutrons, subtract the atomic number from the atomic mass (39.10 for potassium), so in this case, there are 20 neutrons.
A carbon atom always contains six protons. In nature, carbon most commonly has six (12C, carbon-12), seven (13C, carbon-13) or eight (14C, carbon-14) neutrons. However, man-made isotopes of carbon contain as few as two neutrons (8C) or as many as sixteen (22C). Thirteen of the fifteen isotopes of Carbon (i.e. all except 12C and 13C) are radioactive. In addition to neutrons and protons, a carbon atom always has six electrons in orbits around the nucleus.
All sodium isotopes have 11 protons; they differ in their number of neutrons. Sodium-23 is the most common isotope, while sodium-22 and sodium-24 are less common and unstable.
The element with the largest amount of protons that is not man-made is uranium, with 92 protons. All naturally occurring elements with more protons than uranium are only found in laboratories as synthetic elements.
35Cl- has 17 protons, 18 neutrons, and 18 electrons. The negative charge indicates an extra electron compared to the number of protons.
16 protons, 16 electons, 20 neutons
Sulfur has 16 protons, 16 electrons, and typically 16 neutrons in its most common isotope, sulfur-32.
An element can be radioactive regardless of its number of protons. Radioactivity depends on the specific isotopes of an element, which can have different numbers of neutrons. Elements with unstable isotopes that undergo radioactive decay typically have too few or too many neutrons compared to the number of protons.

Barium has 81 neutrons :D
4 neutrons in 3Li7 isotope.
No, aluminum is not man-made. In fact, it is a natural and earth found metal. Aluminum is found in the earth's crust.
Oxygen has 8 protons.
