Oxygen has the valence 2-.
Na- sodium O- oxygen Na2O- Sodium oxide
Sodium oxide is a compound, two sodium atoms for each oxygen atom, or Na2O (if I could do the subscript).
Antimony sulfide; sodium oxide; carbonic acid.
The common name for Na2O is sodium oxide. It is an inorganic compound formed when sodium reacts with oxygen, and it is primarily used in the production of glass and ceramics. Sodium oxide is a white, solid compound that can react with water to form sodium hydroxide.
The charge of Li₂X depends on the identity of the element X. Lithium (Li) has a +1 charge, so in the compound Li₂X, two lithium ions contribute a total charge of +2. To balance this, the element X must have a charge of -2. Therefore, if X is an anion with a -2 charge, such as oxide (O²⁻) or sulfide (S²⁻), then the overall charge of the compound Li₂X is neutral.
The formula for sodium oxide is Na2O. This is because sodium has a +1 charge and oxide has a -2 charge, so you need two sodium atoms to balance out the charge of one oxide ion.
N2O is a neutral molecule, nitrous oxide, it is isoelectronic with CO2. (There is an N2O- anion produced as an unstable intermediate in radiolysis experiments which dissociates to form O- radical anion and nitrogen.
Sodium Oxide is a compound.
It is Sodium Oxide
Na2O is an ionic compound. It consists of sodium ions (Na+) and oxide ions (O2-) that are held together by ionic bonds, which involve the transfer of electrons from the sodium to the oxygen to achieve a stable octet configuration.
Calcium oxide is an ionically bonded compound that contains equal numbers of calcium cations with a charge of +2 and oxide anions with a charge of -2.
Manganese(III) oxide is considered an ionic compound. In this compound, manganese exists as a cation with a +3 charge, while oxygen is an anion with a -2 charge. The electrostatic attraction between the cation and anion results in the formation of an ionic bond.
This compound is sodium hydroxide - NaOH.
The anion in an ionic compound always ends in "-ide" when naming ionic bonds. For example, chloride (Cl-) in sodium chloride (NaCl) or oxide (O2-) in magnesium oxide (MgO).
The charge of sodium oxide is +2. Sodium (Na) has a +1 charge and oxygen (O) has a -2 charge, so in sodium oxide (Na2O) two sodium atoms will combine with one oxygen atom resulting in a +2 charge for the compound.
The formula for the compound between sodium and oxygen is Na2O. This compound is known as sodium oxide and is formed when sodium reacts with oxygen.
If it is a monatomic ion, the ending of its name is changed to -ide. For example, the anion formed by an oxygen atom is called oxide, and the anion formed by the chlorine atom is called chloride.
