Elements with high atomic numbers tend to have _____. more electrons than protons more electrons than neutrons more neutrons tha
2 answers:
Answer:
More neutrons than protons.
Explanation:
Hello,
In this case, it is necessary to know that in an atom, the number of protons are equal to the number of electrons based on the classic atomic theory. On the other hand, protons are equal to the atom's atomic number and neutrons are computed as the difference between the atom's atomic mass and the atom's atomic number, for instance, for ruthenium:
In such a way, an atom tends to have more neutrons than protons but the difference is even greater for elements with high atomic numbers.
Best regards.

The question is incomplete, here is the complete question:
Calculate the pH at of a 0.10 M solution of anilinium chloride . Note that aniline
is a weak base with a
of 4.87. Round your answer to 1 decimal place.
<u>Answer:</u> The pH of the solution is 5.1
<u>Explanation:</u>
Anilinium chloride is the salt formed by the combination of a weak base (aniline) and a strong acid (HCl).
To calculate the pH of the solution, we use the equation:
where,
= negative logarithm of weak base which is aniline = 4.87
C = concentration of the salt = 0.10 M
Putting values in above equation, we get:
Hence, the pH of the solution is 5.1
