How many total electrons are transferred?

li oxidation number is 0, nitrogen is 0, in the compound li is +1 and n is -6. lithium lost 1 electron and nitrogen gained 6 electrons. how is my answer wrong?

6 li(s) + n2(g) → 2 li3n(s)?

For each unit of the reaction (i.e. for every two formula units of Li₃N produced,) six electrons will be transferred.

Explanation:

Lithium is a (new IUPAC) group 1 metal. In most compounds, it loses one atom to acquire an oxidation state of +1.

Nitrogen is a group 15 nonmetal. The oxidation state of N varies greatly from compounds to compounds. Let the oxidation state of N in the compound Li₃N be .

Sum of the oxidation states on atoms in one unit of Li₃N:

.

The oxidation state of all atoms in a neutral compound shall add up to 0. In other words,

.

Solve for :

.

In other words, the oxidation state of N in the compound Li₃N is -3.

The oxidation state of both Li and N were initially 0.

Note that each unit of nitrogen gas, N₂, contains two N atoms. Overall, the six Li atoms transferred electrons to the two N atoms.

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
