Answer 1

Так як саме така електронна формула то це або S, або O. O не підходить, отже S

Answer 2

Determining the Element Based on the Electron Configuration and Mass Fraction in its Highest Oxide

To determine the element based on the given electron configuration and mass fraction in its highest oxide, we can follow these steps:

1. Identify the Element's Electron Configuration: The electron configuration provided is ns² np⁴.

2. Determine the Element's Group: The electron configuration ns² np⁴ corresponds to the group 16 (also known as group VIA) elements on the periodic table.

3. Identify the Element: Based on the electron configuration ns² np⁴ and the fact that the mass fraction of the element in its highest oxide is 40%, we can determine that the element is sulfur (S).

- The electron configuration of sulfur is 1s² 2s² 2p⁶ 3s² 3p⁴ . - Sulfur's highest oxide is sulfur dioxide (SO₂), and its mass fraction in SO₂ is approximately 40% .

Therefore, based on the given information, the element with the electron configuration ns² np⁴ and a mass fraction of 40% in its highest oxide is sulfur (S).
