Based on Table S, the atom of element that has the strongest attraction for electrons in a chemical bond from the options is Chlorine.
<h3>What is Electronegativity?</h3>
Electronegativity can be regarded as the tendency that is been associated to an atom for attraction of electrons to itself.
However, Fluorine is considered as the most electronegative element but based on Table S, Chlorine has the strongest attraction for electrons in a chemical bond .
THESE ARE THE OPTIONS
1 aluminum
2 chlorine
3 magnesium
4 sulfur

Answer:
0.2776
Explanation:
Mean = 15000, SD = 1500
We need to find Cumulative probability: P(X > 15884)
First we need to convert it into normal distribution.
From the attached file, we can see the shaded area we are looking for.
For conversion as follow;
Next to find Z = = 0.59
now we have converted to normal distribution and found the value of Z, we need to find the probability P(X > 15884).
P(X > 15884) = P(Z > 0.59).
From the normal distribution table at Z= 0.59, and greater than 0.59, Probability = 0.2776.
Answer:
-12
Explanation:
We are given information to solve for 2 variables x and y. To solve this I substituted 3x for y in the equation 5x - 4y = 21
So substituting gets us 5x - 4(3x) = 21
and we can solve the equation for x
5x - 12x = 21
-7x = 21
x = -3
Now that we have found x, we can find y simply by putting it in the equation y = 3x
y = 3(-3) = -9
Once we have both variables, we can find the answer to x + y
-3 + -9 = -3 - 9 = -12
So the answer to the question
x + y = -12
