Question

Народ, как определить кол-во электронов на последнем уровне у амфотеров ? к примеру у Mo, Rh, Sn

Answer 1

Посмотреть по табличке менделеева, число электронов на последнем внешнем уровне равно последнему номеру группы.

То есть у Mo 8 электроном на d подуровне, так он в 8 группе (подуровни тоже можно найти в табличке)

у Rh 9

У Sn 4

Answer 2

Ответ: В таблицах описано что и как делать.

Determining the Number of Electrons on the Outermost Shell of Amphoteric Elements

To determine the number of electrons on the outermost shell of amphoteric elements like Mo (Molybdenum), Rh (Rhodium), and Sn (Tin), we need to refer to their electron configurations. The electron configuration provides information about the distribution of electrons in an atom's energy levels or shells.

Unfortunately, the search results provided do not contain specific information about the electron configurations of these elements. However, I can provide you with the general electron configurations for these elements, which can help you determine the number of electrons on their outermost shell.

1. Molybdenum (Mo): - The electron configuration of Molybdenum is [Kr] 5s^2 4d^5. - From this configuration, we can determine that Molybdenum has 7 electrons on its outermost shell.

2. Rhodium (Rh): - The electron configuration of Rhodium is [Kr] 5s^2 4d^8. - From this configuration, we can determine that Rhodium has 8 electrons on its outermost shell.

3. Tin (Sn): - The electron configuration of Tin is [Kr] 5s^2 4d^10 5p^2. - From this configuration, we can determine that Tin has 4 electrons on its outermost shell.

Please note that these electron configurations are based on the periodic table and may vary slightly depending on the specific source or context. It's always a good idea to verify the electron configurations using reliable sources or references.

I hope this helps! Let me know if you have any further questions.
