Answer Both Be and Be 2 + have 4 protons. Both of these two have 5 neutrons. Be is neutral but Be + 2 has 2 units positive charge. Neutral Be will not be attracted towards any electrode unlike Be 2 + which will be attracted towards the negative electrode in the electrolysis process. Explanation Be is neutral as the number of electrons (4) is equal to the number of protons (4). Thus, Be will not be attracted towards any electrode unlike Be 2 + . There are two electrons less as compared to number of protons in Be 2 + . So it is not neutral and it move towards negative electrode in the electrolysis process.

Expert Solution & Answer

Answer to Problem 5E

Both Be and Be² + have 4 protons. Both of these two have 5 neutrons.

Be is neutral but Be + 2 has 2 units positive charge.

Neutral Be will not be attracted towards any electrode unlike Be² + which will be attracted towards the negative electrode in the electrolysis process.

Explanation of Solution

Be is neutral as the number of electrons (4) is equal to the number of protons (4).

Thus, Be will not be attracted towards any electrode unlike Be² + .

There are two electrons less as compared to number of protons in Be^{2 +}. So it is not neutral and it move towards negative electrode in the electrolysis process.
