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.

When an atom becomes on ion with a two-charge the atom?
The group 2 elements form ions with a 2+ charge. For example, Mg2+ and Ca2+. The group 16 elements form ions with a 2- charge. For example, O2- and S2-.
What type of ions will nonmetals form?
Metals form cations and non-metals form anions.
What is the name of the table used to predict which ions will form solid compound precipititates?
This is a solubilty chart; see an example at this link.
Do positive ions form faster than negative ions?
yes positive ions are faster then negative ions
What is uranium ions?
Uranium can form in solutions ions with valencies 3,4,5,6.
What element combined with chloride ion would form an ionic compound?
Chloride ions would form elements with ions of metallic elements. For example, with sodium ions, chloride ions form sodium chloride.
Can ionic compound exist in the form of ions?
In solutions, aqueous medium for an example, ionic compounds can exist as separate ions.
Metals usually form from what types of ions?
Metals usually form cations, or positively charged ions.
When an atom becomes on ion with a two-charge the atom?
The group 2 elements form ions with a 2+ charge. For example, Mg2+ and Ca2+. The group 16 elements form ions with a 2- charge. For example, O2- and S2-.
What kinds of ions do acids and bases form in water?
What kind of ions does a base release in a water solution?
What kind of ions do metals form and what kind of ions do nonmetals form?
Metals for positively charged ions and nonmetals form negatively charged ions.
What is a substance that does not form ions and does not enhance the conductivity of water when it dissolves?
For example compounds with covalent bonds.
What has positive ions and can form ionic compounds?
Metals form positive ions and form ionic compounds with negative ions.
What type of ions will nonmetals form?
Metals form cations and non-metals form anions.
What ions does an acid form?
H+ ions
Ionic bonds form between molecules that have what charge?
Opposite charge. Note that charged molecules are usually referred to as polyatomic ions. For example (NH4)2SO4 would be an example of two oppositely charged polyatomic ions.
What elements does not form monoatomic ions?
Noble gases doesn't form ions.
