Oxygen ion has a charge -2
The given electron configuration corresponds to the ion with a charge of -2, which is the oxide ion (O^2-). This ion is formed by the element oxygen when it gains two electrons to achieve a stable electronic configuration.
The O-N-O bond angles are greater in the nitrate ion (NO3-) compared to the nitrite ion (NO2-).
O2 2-O^2-The conjugate base for HS04 is SO42.
an anion is simply an atom of an element which has 1 or more excess electrons in addition to its own electrons.this is the reason an anion has negative charge equals to the number of excess electrons it has.
Yes, Na2Cr2O7 is an ionic compound containing the polyatomic ion dichromate (Cr2O7)^(2-). Sodium (Na) is a monovalent cation, and dichromate is a polyatomic anion formed by chromium (Cr) and oxygen (O) atoms.
because is always going to be a -
You think probable to a chlorine oxide or to a ion containing O and Cl.

Oxygen, O. Oxygen is in Group 6. It has six electrons in its outer shell. It gains two electrons from one or two other atoms in reactions, forming an oxide ion, O 2-
the symbol for Oxygen is O, the Oxygen ion is 2-. therefore the symbol for the oxygen ion is O2-
Not O3, which is ozone. But O-2 is the most common ion of oxygen.
(H9O4)+ is a complex ion formed from the cation hydronium (H3O)+ and three water molecules.
O2 2-O^2-The conjugate base for HS04 is SO42.
S(2-) : sulfide ion Al(3+) : aluminum ion
H30 typically refers to the hydronium ion (H₃O⁺), which is formed when a water molecule (H₂O) accepts a proton (H⁺). This ion plays a crucial role in acid-base chemistry, as it represents the presence of acidity in a solution. In aqueous solutions, the concentration of H₃O⁺ ions is used to determine the pH of the solution.
