Why do some atoms form positive ions and others form negative ions?

Chemistry
1 answer:
Gemiola [76]4 years ago

Atoms for negative or positive ions depending on whether they lose or gain electrons to achieve the stable octet.  If an atom loses electrons then it would have a positive charge (cation) and if the atom gains electrons then it would become negatively charged (anion).

What is the lowest unoccupied molecular orbital in F2?
Juliette [100K]

Answer:

σ*2pₓ, also called 3\sigma_{u}\text{*}

Explanation:

I have drawn the MO diagram for fluorine below.

Each F atom contributes seven valence electrons, so we fill the MOs of fluorine with 14 electrons.

We have filled the \pi \text{*2p}_{y} and \pi \text{*2p}_{z} MOs.

They are the highest occupied molecular orbitals (HOMOs).

The next unfilled level (the LUMO) is the σ*2pₓ orbital. If you use the symmetry notation, it is called the 3\sigma_{u}\text{*} orbital.

This is the orbital that fluorine uses when it acts as an electron acceptor.

How many moles are in 454 grams of dinitrogen trioxide (N2O3) ?
balu736 [363]

Answer:

5.97 mol

Explanation:

To find the number of moles when given the mass of a substance, we divide the mass of the sample by its molar mass.

so, we get,

nN203 = 454 g / 76.01 g /mol

= 5.97 mol
