Question

Кол-в о електронів на зовні шньому ене ргет. Рівні в атомі втричі більша, ніж в атому Магні ю . Я елек трони в атомі елем ента розміщені на трьох енерге тичних рівнях. Яка формула вищого оксиду цього елемента ? Допоможіть ! Завтра буде опит !! Даю 100 балів та подяку якщо ще напишите формулу леткої сполуки з Гідрогеном цього елемента та обчислите суму індексів

Answer 1

Ответ:

Объяснение:

Магній знаходиться в ІІІ періоді другій А- групі хімічних елементів ПСХЕ, тому на зовнішньому рівні у атома Магнія 2 електрона. Атом хімічного елемента, на зовнішньому рівні якого 2*3 = 6 електронів - це Сульфур, розподіл електронів такий: 2 - 8 - 6. Формула вищого оксиду SO₃; формула леткої сполуки H₂S, сума індексів дорівнює трьом.

Answer 2

Number of Electrons in the Outer Energy Level of an Atom

The number of electrons in the outer energy level of an atom is determined by its position in the periodic table. The outermost energy level is also known as the valence shell, and the electrons in this shell are called valence electrons. Valence electrons are responsible for the chemical behavior of an atom.

To determine the number of electrons in the outer energy level of an atom, you can refer to the periodic table. The periodic table is organized in rows called periods and columns called groups. The period number indicates the energy level of the outermost electrons, while the group number indicates the number of valence electrons.

For example, if we consider the element Magnesium (Mg), it is located in period 3 and group 2 of the periodic table. This means that Magnesium has 3 energy levels, and its outermost energy level contains 2 valence electrons.

Now, let's move on to the element mentioned in the question.

Formula of the Higher Oxide of the Element

To determine the formula of the higher oxide of the element, we need to know the specific element mentioned in the question. Unfortunately, the question does not provide the name or symbol of the element. Therefore, it is not possible to provide the exact formula of the higher oxide without this information.

If you can provide the name or symbol of the element, I would be happy to assist you further in determining the formula of its higher oxide.

Formula of the Volatile Compound with Hydrogen

Similarly, without knowing the specific element mentioned in the question, it is not possible to provide the formula of the volatile compound with hydrogen.

If you can provide the name or symbol of the element, I can help you determine the formula of the volatile compound with hydrogen.

Sum of the Indices

The question also mentions calculating the sum of the indices. However, since the specific element is not provided, it is not possible to calculate the sum of the indices without knowing the formula of the compound.

If you can provide the name or symbol of the element and the formula of the compound, I can assist you in calculating the sum of the indices.

Please provide more information so that I can help you further.
