Explain how a chemical bond forms between potassium and chlorine?
Potassium and chlorine form an ionic bond where electrons are transferred from potassium to chlorine. Potassium, with one electron in its outer shell, donates this electron to chlorine, which has seven electrons in its outer shell. This transfer results in the formation of a potassium ion with a positive charge and a chlorine ion with a negative charge, which are then attracted to each other by electrostatic forces, forming an ionic bond.
Why does chlorine want to gain 1 electron?
Generally, atoms would want to fulfill the octet rule: 8 electrons in the valence shell. This gives the atom a noble gas configuration and is seen as stable. Since the Chlorine atom is in group 7 of the periodic table, it "prefers" to gain one electron instead of losing 7 to attain the stable octet configuration.
Sodium and chloride atoms combine readily because they both tend to lose electrons?
This seems more like a statement of fact than a question. In any case, the statement is half true. Chlorine tends to take electrons, while Sodium tends to lose them. The reason (which is what I suspect you want to find out) is that the electron configurations for Sodium and Chlorine atoms are very unstable. (Sodium Chloride is a compound while Sodium and Chlorine are the elements that make up the compound. When referring to them separately, please use the correct terminology.) Sodium has a lone valence electron, sitting all alone in the outermost orbital of the atom. Atoms will generally try to achieve a "perfect octet", in which the atom in question has 8 valence electrons. It is much easier to lose one electron than it is to try and gain seven more, so Sodium is very prone to losing it's only valence electron. Chlorine has the opposite situation. It has seven valence electrons, just one valence electron short of a perfect octet. Since it is easier to gain one electron than it is to lose seven, it will often react with elements that have just one spare valence electron, such as Sodium.
Why are sodium and chlorine a good match for making a molecule?
Because sodium has the configuration of [Ne]3s1 it will empty the 3s orbital and create an ion with a charge of Na1+. Chlorine will do the opposite. Its configuration is [Ne]3s2,2p5 it will gain a electron to fill its s and p orbital. Because sodium doesnt want its extra s electron and chlorine is looking to gain a p electron, when the two react the electron is transferred to the chlorine. Their electronegativity is so far apart the it forms a stable Sodium Chloride molecule.
How are the topics of ion formation and periodic trends related?
Periodic trends affect how certain elements on the periodic table react with each other. For example, Ionization energy tend : metals want to give off electrons , non metals want to gain electrons. This trend is essentially which elements are likely to react together and how they would react together, which is essentially ion formation (gain or loss of electrons through a reaction).
Why is chlorine reactive and argon is unreactive?
Because of the number of electrons in their valency shells. Chlorine has 7 and so tries to obtain another. Argon has the full complement of 8 and so does not want to gain or lose one.
Why do elements want to gain or lose electrons?
Elements want to gain or lose electrons in order to achieve a stable electron configuration, usually by attaining a full valence shell of electrons. This helps them achieve a more stable, lower energy state, similar to the configuration of noble gases.
What do you call an element that gives away or gains electrons?
These elements are called ions. Elements choose to lose or gain electrons because they want to achieve electronic stability. All metals lose electrons and all non-metals gain electrons to get the respective stable electronic structure they want. As for metalloids, some elements in there gain while some lose electrons. When elements lose or gain electrons, they will form a charge, since the number of protons and neutrons are not balanced now. All non-metals form negative charged ions while all metals form positive charged ions. Compounds are formed when a positively charged ion is attracted to an negatively charged ion by the electrostatic force of attraction. For example, sodium chloride is a compound of sodium ion and chlorine ion. The positively charged sodium ion is attracted to the negatively charged chloride ion to form the compount.

What group does not want to gain or lose electrons?
Noble gases do not want to gain or lose electrons because they already have a stable outer electron configuration. This is known as the octet rule, where they have a full outer shell of electrons. Consequently, noble gases are typically nonreactive and do not readily form chemical bonds.
What is an example of How ions form?
Ions are formed when elements either gain or lose their electrons. For example, Sodium (Na), since it has one electron in its outer shell (valence electron) it will be easier for the atom to lose its one valence electron and give it to an element that would want to gain that one electron, for example, Chlorine. This reaction of gaining or losing electrons would create an either negative ion (gained electrons) or a positive ion (lost electrons). For the example that I did, the element Sodium would lose its one electron in its outer shell making it Na +1 because it would have one more positive charge then it would negative charge.

Does argon want to gain or lose electrons?
Argon is a Noble Gas. Thus it does not lose or gain electrons.
Do atoms gain or lose electrons to achieve a stable electron configuration?
They can do either - and they will. This is the fundamental mechanism behind the science we know as chemistry. Or Yes, they do. Some want to borrow some and some want to loan some out. This is the fundamental mechanism behind the science we know as chemistry.
Which element tends to gain one electron?
Boron, Krypton,Neon, and Radon Krypton, Neon and Radon do not gain electrons. Because an atom wants to have eight electrons in their valence shell or their outermost shell, and Krypto, Neon and Radon are Noble Gases which already have eight in their valence shells, so they don't lose or gain electrons. And as for Boron it want's to gain 5 electrons because it only has three in its valence shell.
Do elements in group 2A gain or loose electrons when they become ions?
Lose 2Alkaline-earth metals have 2 outer shell electrons. All atoms "want" eight. They will achieve a full outer shell by losing or gaining the least number of electrons. Since group 2A elements have two valence electrons, they would either have to gain 6 electrons or lose 2. It is easier to lose 2.
What is neons elements number?
The oxidation number of Neon is 0. It does not want to gain or lose any electrons. It already has a full octet, therefore it remains at 0.
