Oxygen is a 'divalent' atom. To understand why Oxygen is divalent, we need to know how electrons 'stack-up' in an atom.
Oxygen has eight electrons to stack up. This means that it can have two in its first shell, and six in the next. It has two spaces in it's second shell.
Another rule for atoms is that they 'like' to have full shells.
This means that the Oxygen atom finds it easy to pick up two extra electrons. This means it has a tendency to grab two electrons and carry them around, making it 'divalent'.
Other atoms that can behave divalently are Sulphur and Selenium (Group 8 atoms, in the same family as Oxygen) and metals like Magnesium and Calcium, that like to lose two electrons and so have a positive charge, the mirror image of Oxygens's divalency.
What else can I help you with?
Is copper monovalent or divalent?
copper can form monovalent as well as divalent salts
An atom that has lost two electrons is called?
This atom become a cation with the electrical charge +2.
What does tri mean in sulfur trioxide?
"Tri" means Three, oxide means the divalent anion from Oxygen
Would chlorine and iron form a divalent bond?
No, chlorine and iron would not form a divalent bond. Chlorine typically forms a single covalent bond with other elements, and iron can form both divalent and trivalent bonds with other elements, depending on the specific compound involved.
What is the overall charge of Beryllium atom?
The overall charge of a beryllium atom is neutral, meaning it has the same number of protons (+) in the nucleus as it does electrons (-) surrounding the nucleus. Beryllium has 4 protons and typically 4 electrons, resulting in a neutral charge.
What is an alkylidene?
An alkylidene is any of a class of divalent functional groups derived from an alkane by removal of two hydrogen atoms from the same carbon atom.
Is copper monovalent or divalent?
copper can form monovalent as well as divalent salts

What are the example of divalent anion?
Sulfide Dicarbonate

What does tri mean in sulfur trioxide?
"Tri" means Three, oxide means the divalent anion from Oxygen
Is calcium monovalent?
NO, Calcium is divalent. It is having 2 valence electrons
Would chlorine and iron form a divalent bond?
No, chlorine and iron would not form a divalent bond. Chlorine typically forms a single covalent bond with other elements, and iron can form both divalent and trivalent bonds with other elements, depending on the specific compound involved.
What supscripts would be used if an alkaline earth metal and a non metal from group 6a formed an ionic compound?
Usually no subscript would be used, because an alkaline earth metal usually forms a divalent cation and a nonmetal from Group VI(A) forms a divalent anion. As a consequence, the formula unit for such a compound would normally contain only one atom of each type, so that no subscript would be needed.
