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.
Why are cuprous ions less stable than cupric ions?
Cuprous ions (Cu+) have a partially filled d orbital, making them prone to oxidation to Cu2+ in order to achieve a more stable d10 electron configuration. On the other hand, cupric ions (Cu2+) have a full d orbital, resulting in greater stability due to the filled electron subshell.
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.
Is the size of halide atom larger or halide ion?
The size of a halide ion is larger than that of the neutral halide atom. When a halide atom gains an electron to become an anion (e.g., Cl⁻ from Cl), the additional electron increases electron-electron repulsion in the outer shell, resulting in a larger atomic radius. Consequently, halide ions are typically larger than their corresponding neutral atoms.
What oxidation state does chlorine have?
Chlorine can have oxidation states of -1, +1, +3, +5, and +7 in various compounds. Its most common oxidation states are -1 and +1 in the form of chloride ions and hypochlorite ions.
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.
What is argon's oxidation states?
It is always found in the oxidation state of 0
What is the oxidation number of halide ions?
Fluorine: -1 Chlorine: -1, +1, +3, +5, +7 Bromine: -1, +1, +3, +5, +7 Iodine: -1, +1, +3, +5, +7 The normal oxidation state of halides is -1, but with, for example, chlorine other oxidation states exist. Hypochlorites (+1), Chlorites (+3), Chlorates (+5), Perchlorates (+7). The same is true for all halogens, with the exception of fluorine, that seems to like it's -1 status and won't form fluorates.

What is the oxidation state of copper in the compound CuCl2?
+2 oxidation state for the Copper. -1 for the Chloride
What are the rules for assigning oxidation state?
The sum of all oxidation states in a neutral molecule or compound is equal to zero. In ions, the sum of all oxidation states is equal to the ion's charge. For atoms in their elemental form, the oxidation state is zero. Specific rules apply to common elements and their typical oxidation states.
Which of these elements become cations with positive oxidation states Calcium Oxygen Fluorine Magnesium?
Calcium and Magnesium can become cations with positive oxidation states. Calcium commonly forms Ca2+ ions, while Magnesium typically forms Mg2+ ions. Oxygen and Fluorine are nonmetals and usually gain electrons to form anions with negative oxidation states.
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.
Which pair of substances might be involved in an oxidation-reduction reaction that would result in the formation of ions?
One possible pair of substances that could be involved in an oxidation-reduction reaction to form ions is magnesium and oxygen. In this reaction, magnesium would undergo oxidation to form Mg2+ ions, while oxygen would undergo reduction to form O2- ions.
What are halogen ions called?
Ions of the halogen group are called halide ions; their compounds are called halides.
Name of formula AuHSO3?
