Question

Два элемента находятся по соседству в одной группе периодической системы, количества протонов которых соответственно равны 8 и 16. определите элементы и предскажите сходства и различия данных элементов на основе строения их атомов элементы: сходства: различия:​

Answer 1

Ответ:

кислород и сера

Сходство: на внешнем энергетическом уровне 6 электронов у каждого, низшая степень окисления равна -2. Различия: у кислорода - 2 энергетических уровня, у атома серы - три

Объяснение:

Answer 2

Elements and their Similarities and Differences based on Atomic Structure

The two elements that are located next to each other in the periodic table and have respective proton counts of 8 and 16 are oxygen (O) and sulfur (S).

Similarities: - Both oxygen and sulfur belong to Group 16 (also known as Group VIA) of the periodic table, which is commonly referred to as the chalcogens. - They are both nonmetals and are found in the p-block of the periodic table. - Oxygen and sulfur have similar electron configurations. Oxygen has 8 electrons, arranged as 1s² 2s² 2p⁴, while sulfur has 16 electrons, arranged as 1s² 2s² 2p⁶ 3s² 3p⁴. - Both elements can form compounds with other elements, and they are both essential for various biological processes.

Differences: - The atomic number of oxygen is 8, meaning it has 8 protons in its nucleus, while sulfur has an atomic number of 16, indicating it has 16 protons. - Oxygen has 8 neutrons in its nucleus, while sulfur has 16 neutrons. - Oxygen has 8 electrons in its valence shell, while sulfur has 6 electrons in its valence shell. - Oxygen is a gas at room temperature, while sulfur is a solid. - Oxygen is more electronegative than sulfur, meaning it has a greater tendency to attract electrons towards itself in a chemical bond.

These are some of the similarities and differences between oxygen and sulfur based on the structure of their atoms.
