When two different elements combined chemically, a compound is formed. When two different elements are combined physically, a mixture is formed. In the case of barium and sodium, a mixture is formed because they are both metals and they do not combine chemically with each other.
If you mix up the chemical symbols, it will be BANANA, but a banana is a fruit, not a chemical symbol of a compound.
The actual answer is "a mixture of Barium and Sodium". That's all.
Sodium fluoride.
Sodium chloride is an ionically bonded compound formed by the reaction of sodium and chlorine atoms. In the compound, each sodium atom that reacted becomes a positively charged sodium cation and each chlorine atoms that reacted becomes a negatively charged chloride anion.
The chemical formula of barium nitrate is Ba(NO3)2; barium nitrate has six oxygen atoms in the molecule.
Two
Bases combines easily with hydrogen atoms
BaS2 Barium sulfide.
Metals do not form molecules with other metals, they only form alloys. If there was a also a non-metal in this mixture, possibly a nitrate radical, then we would have the makings of an ionic compound. But with just barium and sodium we have an alloy. It is also very difficult to make such an alloy because barium is so much denser than sodium. You could do it more easily in a weightless environment.
Sodium fluoride.
Sodium chloride has two atoms in the formula unit (NaCl): sodium and chlorine.
It has 26 atoms . because Barium has 6 atoms and phosphorus has 4 and oxygen has 16 all in all it has 26 atoms.
Barium hydroxide - Ba(OH)2: 5 atoms.
Barium sulfide (BaS) has two atoms.
Table salt is formed when sodium atoms and chlorine atoms react to form ions.Sodium atoms have 11 electrons and chlorine atoms have 17. In order to have a stable octet ( a full outer shell), the Sodium atom must lose one electron and the Chlorine atom must gain 1.If the sodium atom gives one electron to chlorine, they will both be stable.This is how table salt is formed.
Ba3(PO4)2 Three atoms of barium. Two atoms of phosphorous. Eight atoms of oxygen.
Fluorine is an element and barium is also an element. There is no fluorine in barium and not barium in fluorine.
Sodium chloride is an ionically bonded compound formed by the reaction of sodium and chlorine atoms. In the compound, each sodium atom that reacted becomes a positively charged sodium cation and each chlorine atoms that reacted becomes a negatively charged chloride anion.
The compound sodium bromide is formed by the formation of ionic bonds between sodium and bromide ions.
