Answer:

Noble gases have a stable outer shell

Answer:

Because noble gases have a full octet, their ionization energies are actually quite high. Electron affinity is the amount of energy released when an electron is added to a neutral atom. Because noble gases have stable electron configurations, they have very low electron affinities.

Use IUPAC rules to name this compound. A) nitrogen iodide B) nitrogen triiodide C) mononitrogen iodide D) mononitrogen triiodide

Mariulka [41]

Answer:

Name of the compound is Nitrogen triiodide.

Explanation:

According to the IUPAC rules, to naming of the compound the following formula can be applied.

Prefix + Name of first element + Base name element of second element + Suffix.

The given compound - $NI_{3}$

Name of first element- Nitrogen

Base name element of second element - Iodine

Suffix = 3 = tri

Here, iodine is in ionic form therefore, it becomes iodide. and then suffix will be added in front of the halogen.

Therefore, name of the compound will be Nitrogen triiodide..

The first four electrons shells fill out in what electron configuration?

Sidana [21]

Explanation:

2, 8, 8, 2 is the electron arrangement of Calcium.

The way that the "orbitals", the shells, fill up is given as

$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{6} 4s^{2} 3d^{10}$ . . . etc etc.

It is more stable for the fourth shell to start filling up with an electron pair, and then subsequent electrons filling up the third shell again.

So while potassium 19, is 2,8,8,1

And calcium 20, is 2,8,8,2

Scandium 21 will fill up as, 2,8,9,2

This will continue until we reach Zinc 30, which will fill up as 2,8,18,2. The third shell is now "full", and the fourth shell will now being to fill up.

The fourth orbital starts getting filled up again, Gallium 31, is 2,8,18,3

The larger the energy difference between reactants and products (ΔE), the slower the rate of reaction. true or false

Nikitich [7]

Answer: true

Explanation:

In chemical reactions, an energy barrier exists between reactants and products. The magnitude of this energy barrier determines the rate of reaction. A lesser energy barrier implies that reactants are converted to products faster since the energy required is not too much. On the other hand, a large energy difference between reactants and products will lead to a slow reaction with very poor yield of products if any.
