Halide ions are stable because they have achieved a full outer electron shell through the gain of one electron, which gives them a complete octet configuration. This electron configuration is energetically favorable and leads to lower potential energy, making the ions less reactive. Additionally, the strong ionic bonds formed with cations further contribute to their stability in ionic compounds.
What else can I help you with?
What element has atoms that can form halide ions?
The element that can form halide ions is typically a halogen, such as chlorine, fluorine, bromine, or iodine. These elements have seven valence electrons and can gain one electron to achieve a stable electron configuration, resulting in the formation of negatively charged halide ions (e.g., Cl⁻, F⁻, Br⁻, I⁻). Halide ions are commonly encountered in various chemical compounds and reactions.
What are all the possible oxidation states for the halide ions?
-1 oxidation state
What charge do the halogens form?
When halogens form ions, they are called halide ions. These types of ions have a negative charge due to gaining electrons.
Is fluorite a halide?
Yes, fluorite is classified as a halide mineral. It is primarily composed of calcium fluoride (CaF2), where fluoride ions (F-) are the halide component. Fluorite is known for its colorful variety and is commonly found in a range of geological environments.
If your lab partner believes that all ions are stable how would you explain his belief is wrong?
Not all ions are stable. Ions can be stable or unstable depending on their electron configuration. Some ions are stable because they have a full outer electron shell, while others are not stable and may react to achieve a more stable electron configuration. It's important to understand the concept of stability in relation to electronic configuration when considering ions.

Halide ions are commonly encountered in various chemical compounds and reactions.
Why should you not expect the halides ions to dissolve in mineral oil?
halide ions strongly interact with the counter-ions. However, mineral oil is non-polar. To dissolve the halide ions (and the counter-ions) into mineral oil would drastically raise system energy. Thus it does not work. More simply, halide ions have a charge and won't easily dissolve in non-polar substances, since like-dissolves-like.
Why are ions not stable?
Ions are stable.
What does silver nitrate detect?
Silver nitrate can be used to detect the presence of halide ions (chloride, bromide, iodide) in a solution by forming insoluble silver halide precipitates, which have distinct colors (white for chloride, cream for bromide, and yellow for iodide). It is commonly used in qualitative analysis to identify halide ions and in medical procedures such as the Schirmer's test for the detection of tear production.
What are halogen ions called?
Ions of the halogen group are called halide ions; their compounds are called halides.
What are all the possible oxidation states for the halide ions?
-1 oxidation state
Why is silver nitrate added to halide salts?
Silver nitrate is added to halide salts to test for the presence of halide ions. When silver nitrate is added, a precipitation reaction occurs where silver halide compounds are formed. The color of the precipitate that forms can help identify the type of halide ion present in the salt.
Why silver nitrate is used in argentometric titration?
Silver nitrate is used in argentometric titrations because it forms insoluble silver chloride, silver bromide, or silver iodide precipitates with halide ions present in the solution. The endpoint of the titration is reached when all the halide ions have reacted with silver ions, forming a visible precipitate. This allows for precise determination of the halide ion concentration in the sample.
What is the word equation of photographic film?
The word equation for photographic film is: Silver halide crystals + light → Silver metal + halide ions.
True or False Elements of the halogen family lose one electron to become halide ions?
True. Elements of the halogen family readily lose one electron to attain a stable electron configuration and become halide ions with a negative charge. This makes them highly reactive and likely to form ionic bonds with other elements.
What charge do the halogens form?
When halogens form ions, they are called halide ions. These types of ions have a negative charge due to gaining electrons.
Why add dilute nitric acid with silver nitrate to test for halide ions?
The nitric acid reacts with other ions that might precipitate with silver nitrate. Doing this first gets these other unwanted precipitates out of the way. If you are testing with Fluoride as your halide remember that silver nitrate does not precipitate with Fluoride, so no precipitate does not mean that halide ions are not present.
