What does sodium plus oxygen make?
Sodium is a very reactive metal, it tends to react with oxygen to form sodium oxide but this is an unstable compound and soon reacts with hydrogen to form sodium hydroxide. Sodium is the metal reacts vigorously with oxygen and water. 4 Na + O2 → 2 Na2O.
What does the structure of NaCl look like?
NaCl has a cubic unit cell. It is best thought of as a face-centered cubic array of anions with an interpenetrating fcc cation lattice (or vice-versa). The cell looks the same whether you start with anions or cations on the corners. Each ion is 6-coordinate and has a local octahedral geometry.
How is NaCl formed explain with diagram?
Sodium chloride is a compound formed from the ionic bonding of sodium and chloride. Sodium chloride is formed when sodium atoms interact with chlorine atoms. Sodium will donate an electron (which is a negatively-charged particle) to chlorine. This makes sodium slightly positive and chlorine slightly negative.
What is the formula for a compound made from Na+ and O2 −?
In NaCl, sodium (Na) is +1 and the chloride is 1. In MgO the magnesium is +2 and the oxygen (O) is 2 and so again the charges cancel each other out….Formulas of Ionic Compounds.

How many valence electrons does NaCl have?
The Lewis Structure for the Salt NaCl, shows two ions which have their (Now) outer shells of electrons filled with a complete octet. In the case of the sodium cation, the filled shell is the outermost of the ‘core’ electron shells. In the Chloride ion, the outer shell of valence electrons is complete with 8 electrons.
How NaCl lattice is formed?
The structure of NaCl is formed by repeating the face centered cubic unit cell. It has 1:1 stoichiometry ratio of Na:Cl with a molar mass of 58.4 g/mol. Compounds with the sodium chloride structure include alikali halides and metal oxides and transition-metal compounds.
What type of bond is NaCl?
Ionic bonds
Ionic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl.
How is sodium chloride different from oxygen?
If you like, you can say that sodium chloride is an ionic compound. Oxygen in the atmosphere is a molecule because it contains molecular bonds. It is not a compound because it is made from atoms of only one element – oxygen.
What type of bond is Na and O?
So, Is Na2O ionic or covalent? Na2O is an ionic compound. It consists of 2Na+ and O2- ions which are held together by ionic bonding. The bond formed between the metal, sodium (Na), and nonmetal, oxygen (O) is ionic, due to the large gap of electronegativity difference that exists between them.
What does the formula Na2O mean?
sodium oxide
In sodium oxide, there are two sodium atoms for every oxygen atom, so its formula is shown as Na 2O.
How many Lewis dots does sodium have?
one dot
Sodium has an electron configuration of 2-8-1, therefore it has one valence electron, and needs one dot.
How many valence electrons does oxygen have?
six valence electrons
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.
How many electrons does oxygen have?
2, 6Oxygen / Electrons per shell
What is molecular structure of NaCl?
NaClSodium chloride / Formula
The structure of NaCl is formed by repeating the face centered cubic unit cell. It has 1:1 stoichiometry ratio of Na:Cl with a molar mass of 58.4 g/mol. Compounds with the sodium chloride structure include alikali halides and metal oxides and transition-metal compounds.
Is O2 a covalent or ionic bond?
So, Is O2 ionic or covalent? O2 is a covalent molecule because each oxygen atom needs two valence electrons to complete its octet. To meet this need, each oxygen atom shares two of its electrons with the other oxygen forming a strong oxygen-oxygen double shared covalent bond.
Is NaCl covalent or ionic?
Ionic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons.
Why is sodium chloride considered a compound but oxygen gas is not?
Why is sodium chloride (NaCl) considered a compound, but oxygen gas is not? A compound is formed when two or more different kinds of atoms chemically bonded together (NaCl); oxygen gas is 2 oxygen atoms bonded together.
