How many subatomic particles does lead has?

Lead has a total of 82 subatomic particles, which includes 82 protons and typically 126 neutrons in its most common isotope. Electrons can vary in number based on the charge of the ion.


What a ion?

An ION is an atom that has lost or gained electrons. Thereby becoming a charged species. Once an atom becomes a charged species it is NO longer an atom but an ION . e.g. Sodium atom, symbol ' Na '. has 11 protons, 12 neutrons, and 11 electrons. When it loses (ionises) an electron it becomes a sodium ion. So sodium now has 11 protons, 12 neutrons, and 10 electrons . 11 protons (11+) and 10 electrons (10-). Doing a little sum 11+ 10- = 1(+) Hence the charge on the sodium ion is'+1' . Symbolically, shown as ' Na^(+) ' . and is named a sodium CATION. Similarly Chlorine atom, symbol ' Cl '. has 17 protons, 18 neutrons, and 17 electrons. When it has electron affinity it gains an electron it becomes a chloride ion. So chlorine now has 17 protons, 18 neutrons, and 18 electrons . 17 protons (17+) and 18 electrons (18-). Doing a little sum 17+ 18- = 1(-) Hence the charge on the chloride ion is'-1' . Symbolically, shown as ' Cl^(-) ' . and is named a chloride ANION.


How many neutrons are found in argon?

There are 18, 20 or 22 neutrons.


What subatomic particles could be changed without changing which element the atom?

You are probably referring to neutrons which are often found within the nucleus of an atom in numbers different from the protons. An atom of the element carbon, for instance, normally consists of 12 protons, 12 electrons and 12 neutrons. However, an isotope of carbon known as C13 consists of 12 protons, 12 electrons and 13 neutrons.
