Hello there.

How many is an octet of electron

Referring to the octet rule, atoms attempt to get a noble gas electron configuration, which is eight<span> valence electrons. Sodium has one valence electron, so giving it up would result in the same electron configuration as neon. Chlorine has seven valence electrons, so if it takes one it will have </span>eight<span> (an octet).</span>

Coal like graphite is composed of carbon. Unlike graphite, coal is formed by decayed, once living matter. Is it a mineral?
Simora [160]
Coal is not a mineral. It's not a mineral because minerals are inorganic. Coal is organic because it comes from decayed living matter.

Each energy sublevel contains __________ number of electrons. For example, sublevel D can hold up to _______ electrons. A. the s
Annette [7]

Answer:

Each energy sublevel contains a different number of electrons. For example, sublevel D can contain up to 10 electrons

Explanation:

The atoms are surrounded by propellers that within each propeller there is a certain number of electrons, these electrons jump from orbit to orbit according to the amount of energy they have. The four levels that make up the electronic cloud that surrounds an atom are: s p d f.

When these electrons change orbit or level they release energy in the form of light, which is known as a photon.

A compound is 44.7% P and the rest O. Determine its emperical formula.
svet-max [94.6K]

Answer:  

P₅O₁₂

<em>Explanation:  </em>

Assume that you have 100 g of the compound.  

Then you have 44.7 g P and 55.3 g O.  

1. Calculate the <em>moles</em> of each atom  

Moles of P  = 44.7 × 1/30.97 = 1.443 mol Al  

Moles of O = 55.3 × 1/16.00 = 3.456 mol O  

2. Calculate the <em>molar ratios</em>.  

P: 1.443/1.443 =   1  

O: 3.456/1.443 = 2.395

3. Multiply by a number to make the ratio close to an integer

P:  5 × 1         =  5

O: 5 × 2.395 = 11.97

3. Determine the <em>empirical formula </em>

Round off all numbers to the closest integer.  

P:   5

O: 12

The empirical formula is <em>P₅O₁₂</em>.
