The total percentage of sales of the Model A is 47.37%.

Based on the fact that the selling price of model B is 60% more than the selling price of model A, the calculation below helps show how many percent of the total sales the model A represents.

<h3>Calculations and Parameters</h3>

Given:

Model A: 9,000

Model B: 10,000

Thus, the Total sales = model A + model B

= 9 + 10

= 19

Therefore, the total percentage of sales of the Model A = 9/19 × 100

= 0.473684210526315 × 100

= 47.367%

considering periodic trends, valence electrons in which of the following atoms experience the greatest effective nuclear charge

Anni [7]

The <em>effective nuclear charge</em> is the difference between the atomic number an element and the shielding constant. Hence, the atom which experiences the greatest nuclear charge is Sulphur, S.

<u>Calculating the greatest effective nuclear charge</u>, :

$Z_{eff} = Z - S$

Z = Atomic number ; S = shielding constant

<u>For Magnesium, Mg</u>:

Z = 12

S = 10

$Z_{eff} = 12 - 10 = 2$

<u>For Aluminium, Al</u>:

Z = 13

S = 10

$Z_{eff} = 12 - 10 = 3$

For Sulphur, , S:

Z = 16

S = 10

$Z_{eff} = 16 - 10 = 6$

Therefore, the atom whuch experience the greatest $Z_{eff}$ is Sulphur.
