The element group that is least likely to form ions is Group 2. This group contains the alkaline earth metals, which are not very reactive.
Oxygen is least likely to form an ion because it has a high electronegativity and tends to gain electrons rather than lose them, making it less likely to form a positive ion (cation).
every element
The element with a valence electron configuration of ns2 np4 is sulfur (S). Since it needs to gain 2 electrons to achieve a stable electron configuration, it is most likely to form an ion with a charge of -2.
Iodide is not a metal. It is the ion form of iodine, a non-metal element.
Fluoride ion (F-) is not an element, but an ion formed from the element fluorine (F). Fluorine is a chemical element on the periodic table, while fluoride ion is a negatively charged particle resulting from the gain of an electron by a fluorine atom.
Oxygen is least likely to form an ion because it has a high electronegativity and tends to gain electrons rather than lose them, making it less likely to form a positive ion (cation).
Helium is the least likely noble gas to form an ion due to its stable electronic configuration with a full valence shell of electrons.
Fluorine is the element with the highest electronegativity, making it more likely to form an ion.
Oxygen is the period 2 element most likely to form an ion with a charge of minus 2 because it readily gains two electrons to achieve a stable electronic configuration.
An element with a large negative electron affinity is more likely to form a negative ion because it strongly attracts electrons to achieve a stable electron configuration. This results in the formation of negatively charged ions.
which element can only formed one ion
In compounds, bromine is most likely to form the bromide ion, which has a charge of -1. This ion is commonly found in various ionic compounds and salts.
Chlorine is most likely to form the chloride ion, which has a charge of -1.
An element is most likely to form an ion when it has one or a few electrons in its outer shell, making it easier to gain or lose electrons to achieve a stable electron configuration. This is typically observed in elements at the far left or far right of the periodic table, such as alkali metals and halogens.
Oxygen is most likely to form the oxide ion (O2-) by gaining two electrons.
