The metallic ion in this case is Na+, or sodium.
If there is a metal ion in a chemical formula, it will be the one written at the beginning.
Na2S
Marble is mainly composed of CaCO3 (calcium carbonate, limestone) in which calcium is the metallic ion.
Number of valence electrons-The greater the number of freely mobile valence electrons, the higher the charge of positive metal ion, the stronger the metallic bond. Size of metal atom or ion-The smaller the size of the metal ion, the closer the nuclei of metal cations are to the delocalized mobile electrons, the stronger the forces of attraction between the electrons and nuclei, the stronger the metallic bonds.
Sodium sulfide
It will dissolve.
Sodium and sulfur make sodium sulfide together. 2Na+ (2 cations) and S2- (anion) make Na2S (compound)
This ion is sodium, Na+.
it is a negative ion because silver doesnt attracts positive ions which makes it more metallic it is a negative ion because silver doesnt attracts positive ions which makes it more metallic
Pb2+
Na2S
No, Sulfur Trixoxide SO3 is a molecule. There is a polyatomic ion called the Sulphite ion which has the formula SO32-.
No. Na2S is highly basic.
The name for the compound with the formula Na2S is sodium sulfide.
Cu^2+
Na2S is basic.
Sodium sulfide is Na2S. Two ions can be separated: Na+ and S=. The negative ion S= is the anion.
Ammonia dissolves in water to form ammonium hydoxide, not a meetallic ion in sight!
