Answer:

Answer: (b) F

Explanation:

Sodium has 1, magnesium has 2 and Aluminium has 3 electrons in its outermost shell whereas Fluorine has 7 electrons in its outermost shell hence Fluorine does not lose electrons easily.

The electronic configuration of fluorine is 2,7.

Fluorine is the ninth element with a total of 9 electrons.

The first two electrons will go in the 1s orbital.

The next 2 electrons for F go in the 2s orbital.

The remaining five electrons will go in the 2p orbital. Therefore the F electron configuration will be 1s22s22p5.

How many moles of aluminum are equivalent to 4.816 x 1024 atoms?
CaHeK987 [17]

Answer:

<h2>8 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{4.816 \times  {10}^{24} }{6.02 \times  {10}^{23} }  = 8 \\

We have the final answer as

<h3>8 moles</h3>

Hope this helps you

Suppose you have designed a new thermometer called the x thermometer. On the x scale the boiling point of water is 129 ?x and th
djyliett [7]

(x1,y1) (x2,y2)  

(32,15) (212,135)  

y = mx + b  

m=(y2-y1)/(x2-x1)  

m=.66667  

y = .66667*(x) + b  

Plug in #s to test for b value  

15 = .66667*(32) + b  

b = -6.334  

y = mx + b  

y = .6667*(x) + (-6.334)  

F = .6667*(F) + (-6.334)  

F = (.6667*(F) = -6.334  

(F - .6667F) = -6.334  

F(1 - .6667) = -6.334  

F = -19  

ThermX = F @ -19 degrees
