Why magnesium ion has a charge of 2+?
Explanation: Magnesium is under group 2 that also has a valence electron of 2. To achieve stability and to follow the octet rule, these 2 electrons in the outer shell will be removed making this atom into an ion with a 2+ charge.
Why is the charge on an Aluminium ion 3+?
The charge of an aluminum ion is typically 3+. This is because the element’s atomic number is 13, reflecting the fact that it has 13 electrons and 13 protons. The valence shell of aluminum has three electrons, and per the octet rule, these three electrons are lost resulting in just 10 electrons and 13 protons.
What charge does aluminum have when it becomes an ion?
+3

Does a cation have a negative charge?
A cation is a positively charged ion with fewer electrons than protons while an anion is negatively charged with more electrons than protons, because of their opposite electric charges; cations and anions attract each other and readily form ionic compounds.
What is oxide’s charge?
Oxide trapped charges are holes or electrons that are trapped from ionizing radiation. These can also be removed using low temperature annealing. Mobile oxide charges are contaminants from Na+, Li+, or K+ ions that can occur during the fabrication process.
Which ion has a charge of 3+?
phosphate
Which polyatomic ion has a charge of 2+?
The carbonate ion consists of one carbon atom and three oxygen atoms, and carries an overall charge of 2−. The formula of the carbonate ion is CO2−3. The atoms of a polyatomic ion are tightly bonded together, and so the entire ion behaves as a single unit.
