What is the ratio of nitrogen atoms N to oxygen atoms O in a compound with the formula N2O5 is the same as the compound NO2?
These ratios are not identical. In N2O5 the ratio is 2/5. In NO2 the ratio is 1/2.
What is the difference between nitrogen oxide and nitrogen dioxide?
No. Nitrogen dioxide is a compound of nitrogen an oxygen, meaning that the two elements are chemical bonded together to form a different chemical with its own unique set of properties. In a mixture the nitrogen and oxygen would not be bonded to each other and would retain their individual properties.
Why only lithium form nitrides?
Lithium is the only alkali metal (group 1) to form a nitride when burnt in air. (This is however common with the alkaline earth metals (group2), e.g. Mg3N2 . Note that sodium nitride is known. the 3 :1 ratio of elements in the group 1 nitrides leads to a high coordination number for the nitride ion in a lattice. Lithium has the smallest ionic radius of all of the group 1 metals. The structure of Li3N is unusual - each nitrogen is surrounded by eight lithium atoms, 6 in the same plane. The determination as to why one rection goes and an other doesn't is complex and requires an understanding of the thermodynamics, the so-called Born-Haber cycle. In VERY simple terms it is probably the stability of this odd structure that makes this compound stable whereas Na3N, K3N etc (where Na, K etc are bigger than Li) are not. Sodium nitride, Na3N is a strange solid- a semiconductor with ionic character- and has a different structure from Li3N with 6 coordinate nitrogen.
Is sodium fluoride an element compound or mixture?
Sodium Fluoride is an Ionic Compound. It's Fluorine and Sodium with the formula NaF.
Is the ratio nitrogen to oxygen changed by altitude?
No, the ratio of nitrogen to oxygen is not changed by altitude.
Is N2 ionic compound?
No, it is a molecular compound. If it was ionic, the ratio of the subscripts-"2" for Nitrogen and "4" for Oxygen; (2:4)- would have to be reduced to the lowest whole number ratio, which is 1:2. Also, both Nitrogen and Oxygen are nonmetals. All ionic compounds have metals in them, so it definitely not a ionic compound.
What determines the ratio of ions in an ionic compound?

Does the chemical formula of an ionic compound show the atoms in a molecule?
No. The chemical formula of an ionic compound is a formula unit and represents the lowest whole number ratio of ions in the compound. Ionic compounds are not made of molecules.
What is the lowest whole number ratio of ions in an ionic compound called?

It is a formula unit.
When nitrogen and hydrogen combine what will be the ratio of hydrogen atoms to nitrogen atoms in a molecule resulting compound?
There will be three hydrogen atoms per nitrogen atom, forming the compound ammonia with formula NH3.
Is the ionic compound between barium and oxygen present in one-to-one ratio?
Yes.
