Answer:

See explanation

Explanation:

The valence electrons are electrons found on the valence (outermost) shell of an atom.

When an atoms form compounds, there is an exchange of valence electrons between the atoms of one element and the atoms of another element.

Let us consider a typical example, sodium has one valence electron and chlorine has seven valence electrons. This means that chlorine needs one electron to complete its octet while sodium needs to release one electron in order to attain the octet structure.

So, sodium gives out its one electron and becomes a stable sodium ion and chlorine accepts that electron and becomes a stable chloride ion. This is how the compound sodium chloride is formed.

pshichka [43]

Answer:

About 19.64 pounds of carbon dioxide are produced from burning a gallon of gasoline. On the other hand, 22.38 pounds of carbon dioxide are produced from burning a gallon of diesel. So, different fossil fuels will give different amounts of carbon dioxide to be released.

Identify the element whose highest energy electron would have the following four quantum numbers?
ad-work [718]

C. 6, 1, 0, -1/2

Explanation:

The four quantum numbers are:

  • Principal quantum number (n): this represents the energy level in which an orbital is located.
  • Azimuthal quantum number gives the shape of the orbitals in subshells accommodating the electrons.
  • Magnetic quantum number gives the number of spatial orientations or degeneracy of the orbitals in the subshells.
  • Spin quantum number describes the spinning of an electron in either clockwise or anticlockwise directions.

To know the electron with the highest energy, we use the principal quantum number values.

n values takes whole numbers i.e n = 1,2,3,4,5,6,7.............

The higher the value, the higher the energy level.

From the given quantum numbers, C has the highest energy levels.
