Answer:
Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group.
Explanation:
Hope it is helpful....
Keep in mind that atomic number is the number of protons in the atom of the element. Therefore, in the case where there are 78 protons, we can conclude that the atomic number of this element is ALSO 78.
Let me know if you need anything else.

Answer:
[H⁺] = 1.30X10⁻⁴ M
Explanation:
the problem will be solved by using Nernst's equation, which is :
In the given equation
n = 2
Q = ![=\frac{[Zn^{+2}][p_{H2}]}{[H^{+}]^{2}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5BZn%5E%7B%2B2%7D%5D%5Bp_%7BH2%7D%5D%7D%7B%5BH%5E%7B%2B%7D%5D%5E%7B2%7D%7D)
Putting values
![0.53= 0.76 - \frac{0.0592}{n}log(\frac{1X1}{[H^{+}]^{2}})](https://tex.z-dn.net/?f=0.53%3D%200.76%20-%20%5Cfrac%7B0.0592%7D%7Bn%7Dlog%28%5Cfrac%7B1X1%7D%7B%5BH%5E%7B%2B%7D%5D%5E%7B2%7D%7D%29)
on calculating
[H⁺] = 1.30X10⁻⁴ M
