Argon is usually electrically neutral and has no charge. It is possible to ionize it, however (at very high temperatures or by means of a high voltage) at which point it would have a positive charge.
Chlorine atom has 17 electrons. It is readily accepting an electron from another atom to obtain its stable electron configuration (of argon). A chloride ion has 18 electrons.
Potassium is a metal element. There are 19 electrons in a single atom.
there are 12 nuetrons in an atom of magnesium
That depends on the isotope, as Argon has three different stable isotopes and many different radioactive isotopes.
It depends entirely on the identity of the atom. Each element has a unique number of protons. In fact, the number of protons in an atom is what tells you what element it is! For instance, hydrogen (H) has 1 proton, carbon (C) has 6 and copper (Cu) has 29.If you look at the periodic table, than you'll see that each element in the table has a number. That number is called the atomic number, and that number is exactly equal to the number of protons in that particular element's nucleus.See the Web Links to the left of this answer for a periodic table

Twelve. Each proton has one positive charge.
2
A helium atom has two positive charges, as it contains two protons in its nucleus. These protons contribute to the atomic number of helium, which is 2. Additionally, helium typically has two electrons, which balance the positive charges, making the atom electrically neutral.
Argon has 18 electrons.
It depends on the atomic weight and how many positive, negative, and neutral charges are in the atom. Marshmellows!
Something is neutral when there are just as many positive charges as negative charges. A normal atom has just as many positive protons in its nucleus as it has negative electrons orbiting around its nucleus.
There are 6 2p electrons in argon.
Same amount as the Proton count - 18
There are 18 in each atom.
There are 18 protons in an Aragon atom.
Boron typically has three positive charges (protons) in its nucleus, thus making it a positively charged ion.
