Because they are not on the periodic tsble they are on the back and they goes together
Answer:
Fluorine
General Formulas and Concepts:
<u>Chemistry</u>
- Reading a Periodic Table
- Periodic Trends
- Electronegativity - the tendency for an element to attract an electron to itself
- Z-effective and Coulomb's Law, Forces of Attraction
Explanation:
The Periodic Trend for Electronegativity is up and to the right of the Periodic Table.
Fluorine is Element 9 and has 9 protons. Radium is Element 88 and has 88 protons. Therefore, Radium has a bigger Zeff than Flourine.
However, since Radium is in Period 7 while Fluorine is in Period 2, Radium has more core e⁻ than Fluorine does. This will create a much larger shielding effect, causing Radium's outermost e⁻ to have less FOA between them. Fluorine, since it has less core e⁻, the FOA between the nucleus and outershell e⁻ will be much stronger.
Therefore, Fluorine would attract an electron more than Radium, thus bringing us to the conclusion that Fluorine has a higher electronegativity.
I'm guessing water vapour. i can't think of any other gas limited to only hydrogen and oxygen
hope it helps :)
Answer:
<h2>10 m/s</h2>
Explanation:
Her average speed can be found by using the formula

d is the distance
t is the time taken
From the question we have

We have the final answer as
<h3>10 m/s</h3>

Answer:
The solubility product of zinc sulfide is
.
Explanation:
Solubility of the zinc sulfide = 

S S
The expression of solubility product is given by :
![K_{sp}=[Zn^{2+}]\times [S^{2-}]](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BZn%5E%7B2%2B%7D%5D%5Ctimes%20%5BS%5E%7B2-%7D%5D)


The solubility product of zinc sulfide is
