Iodide ions have a -1 charge.
Example: The chemical formula of Copper (II) Iodide would be CuI2 because Copper (II) has a +2 charge and Iodide has a -1 charge.
Iodine will have a -1 charge when it forms an ion, because it must gain one electron to become isoelectronic with nearby xenon.

How are positive charged ions formed?
Positive charged ions are formed when an atom loses one or more electrons, leaving behind more protons than electrons. This imbalance in charge creates a net positive charge on the ion.
How do you find positive and negative charged ions?
Positive ions are formed when an atom loses electrons, resulting in a net positive charge. Negative ions are formed when an atom gains electrons, resulting in a net negative charge. In chemical reactions, ions can be identified based on their charge and presence of a positive or negative sign.
What is the charge on ions formed from atoms of Na?
because Na has one electron in its outer shell, the charge of the ion is Na+
What is formed when a single atom of Krypton?
When a single atom of Krypton gains or loses electrons, it becomes an ion. These ions can have a positive charge if it loses electrons or a negative charge if it gains electrons.
When is An ion is formed when an atom?
An ions is formed when an atom gains or loses electrons.
When are ions formed?
Ions are formed when an atom gains or loses electrons. When an atom loses electrons the Ion that is formed has a positive charge.
What will the charge be on an ion formed from iodine?
An ion formed from iodine typically has a charge of -1, as iodine typically gains one electron to achieve a more stable electron configuration.
One calcium atom for every two iodine atoms?
The compound you are describing is calcium iodide (CaI2), which consists of one calcium atom and two iodine atoms. Calcium ions have a +2 charge, while iodine ions have a -1 charge, leading to the 1:2 ratio in the compound.
What is the formula for the ionic compounds K and I?
The ion for Potassium has a charge of 1+.The ion for Iodine has a charge of 1-.This means that in order to make the overall charge of a unit of a compound of Potassium and Iodine, there must be one atom of Potassium and one atom of Iodine.Therefore, when K+ and I- are bonded, they make the ionic compound of KI.
When electrons are lost from an atom what type of ions are formed?
When electrons are lost from an atom, positively charged ions are formed. These ions are called cations.
What is the charge of the ion formed when a potassium atom loses one electron?
K+ ions
What is the charge of ions formed from the atom of sodium?
Ions formed from sodium atoms have a charge of +1. Sodium easily loses one electron to achieve a stable electron configuration, resulting in a sodium ion with a +1 charge.
How are positive charged ions formed?
Positive charged ions are formed when an atom loses one or more electrons, leaving behind more protons than electrons. This imbalance in charge creates a net positive charge on the ion.
How do you find positive and negative charged ions?
Positive ions are formed when an atom loses electrons, resulting in a net positive charge. Negative ions are formed when an atom gains electrons, resulting in a net negative charge. In chemical reactions, ions can be identified based on their charge and presence of a positive or negative sign.
Electrostatic Charge of iodide?
Iodide ions have a negative charge of -1 due to the gain of an extra electron by an iodine atom. This charge results from the imbalance of protons (positive charge) and electrons (negative charge) in the ion.
What is the definition of cations anions monatomic ions and polyatomic ions?
Cations are positively charged ions formed by losing electrons. Anions are negatively charged ions formed by gaining electrons. Monatomic ions consist of a single atom with a positive or negative charge. Polyatomic ions are ions made up of two or more atoms covalently bonded together, carrying a net charge.
What type of ions positive or negavie are formed by losing electrons?
Positively charged ions are formed by losing electrons. In a neutral atom, the number of protons and electrons are equal. If an atom loses an electron, it then contains one more proton than electrons. Since protons have a positive charge, the atom becomes an ion with a 1+ charge.
