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 = Atomic number ; S = shielding constant
<u>For Magnesium, Mg</u>:
Z = 12
S = 10
<u>For Aluminium, Al</u>:
Z = 13
S = 10
For Sulphur, , S:
Z = 16
S = 10
Therefore, the atom whuch experience the greatest
is Sulphur.

Answer:
because we are smart and use the internete
Explanation:
The length of x to the nearest tenth is; D: 38.6 m
<h3>Trigonometric ratios</h3>
The image of the triangle is missing and so i have attached it.
From the image attached, we can find the value of x by using trigonometry ratio.
We see that;
Thus;
10/x = cos 75
10/x = 0.2588
x = 10/0.2588
x = 38.64 m
Approximating to the nearest tenth gives;
x = 38.6 m

Answer:
(15/17 = sin ∠ JLK)
(first option listed)
Explanation:
the "sin ∠ JLK" is what we can simply think of as the inside measurement of angle/corner L. (L is the letter in the middle of ∠ JLK , and if you imagine drawing a line from J to L to K, you would see that the only angle you formed both sides of is corner L)
so, we are looking for the sin of L.
(SOH CAH TOA)
we know that
sin = opposite / hypotenuse
However, we do not have the opposite value of this triangle <em>yet. </em>
-----
we can solve the length of the opposite side with the Pythagorean theorem:
a² + b² = c²
8² + b² = 17²
64 + b² = 289
- 64 - 64
b² = 225
√b² = √225
b = 15
----
so, to solve for sin L,
(sin = opposite / hypotenuse)
we should divide the opposite (15) over the hypotenuse (17)
so, 15 / 17 = sin L
(15/17 = sin ∠ JLK)
