What is the molecules formula of salt?
The molecular formula of salt is :NaCl (Sodium Chloride)
Which has the largest atomic radius Br or Na?
Na has a larger atomic radius than Br. This is because Na is a metal and atoms in metals have larger atomic radii compared to nonmetals like Br, which has a smaller atomic radius due to its higher effective nuclear charge.
Which elements have compounds of the general formula XY?
Alkali metals (like Na and K) and halogens (like Cl and Br) have the general ionic formula format XY (X+ and Y- in solution)
What the symbols and number mean in the chemical formula of an ionic compound?
Symbols are the chemical symbols of elements.Number are the number of a specific atom in the molecule or formula unit. For example: Na2SO4- Na, S, O are the chemical symbols of sodium, sulfur and oxygen- 2 is the number of sodium atoms in the formula unit; 4 is the number of oxygen atoms in the formula unit
Why is na2so4 not a molecular formula?
Na2SO4 is not a molecular formula because it represents an ionic compound, sodium sulfate. In ionic compounds, the elements are held together by ionic bonds rather than sharing electrons in covalent bonds like in molecular compounds. The formula Na2SO4 indicates that there are two sodium ions (Na+) for every sulfate ion (SO4^2-).
What is the name for the molecular compound Na Br?
Sodium Bromide
What is the molecular formula for sodium hydroxide?
For sodium oxide, the empirical formula is the same as the formula unit, Na2O. (If any formula unit or molecular formula contains an atomic symbol with no following subscript, the empirical and actual formulas will be the same.)
What is the formula unit of sodium?
The formula unit of sodium is Na, which represents one atom of sodium.
What is the chemical formula and name of the ionic compound that can be formed from Na and Br?
The ionic compound formed from sodium (Na) and bromine (Br) is sodium bromide, with the chemical formula NaBr.
What is the molecular formula of sodium?
It is just written as Na
What is the formula of anion in the ionic compound sodium bromide?
The formula of the anion in sodium bromide is Br^-. Sodium bromide is composed of the sodium cation (Na^+) and the bromide anion (Br^-), which combine in a 1:1 ratio to form the compound NaBr.
What is the concept of the ratio of elements in a compound such as table salt?
The formula unit of sodium chloride is NaCl; the atomic ratio Na/Cl is 1.Note that the expression molecular formula for NaCl is not correct.
What is the Oxidation number of Na Br?
+1 for Na -1 for Br
Molecular formula for sodium?
Sodium is a chemical element not a molecule; the symbol is Na.
What elements are not in the same physical states Na Hg Br Na and Hg Hg and Br?
Na is solid. Hg, Br are liquids at room temp.
What is the formula mass for NaCl?
The molecular mass is the sum of the atomic weights of the contained elements in the formula unit. 22,98976928 (atomic weight of Na) + 35,45 (conventional atomic weight of chlorine) = 58,43976928
Formula for sodium bromide?
NaBr When combining a metal with a nonmetal, Name the metal (Sodium), then the stem of the nonmetal + ide (Brom + ide). It is NaBr because Na has an oxidation state of +1 and Br has an oxidation state of also +1 therefore you only need one of each to balance themNaBr
