Question

Сколько элементов третьего периода образуют оксиды, взаимодействие которых с водой даёт кислоту?

Answer 1

Очевидно, что не 10.
Элементы третьего периода - Na, Mg, Al, Si, P, S, Cl, Ar.
Из них 3 (P, S, Cl) дают оксиды, которые при взаимодействии с водой дают кислоты.

Answer 2

Number of Elements in the Third Period Forming Oxides Reacting with Water to Produce an Acid

The third period of the periodic table consists of elements from sodium (Na) to argon (Ar). The elements in this period form oxides that can react with water to produce acids. Let's find out how many elements in the third period form such oxides.

The elements in the third period of the periodic table are: 1. Sodium (Na) 2. Magnesium (Mg) 3. Aluminum (Al) 4. Silicon (Si) 5. Phosphorus (P) 6. Sulfur (S) 7. Chlorine (Cl) 8. Argon (Ar)

The number of elements in the third period that form oxides reacting with water to produce an acid is 3.

Verification of the Claim

The claim that the number of elements in the third period forming oxides reacting with water to produce an acid is 3 is supported by the information from the search result snippet.

This information aligns with the properties of the elements in the third period of the periodic table, where sodium (Na), magnesium (Mg), and aluminum (Al) are known to form oxides that react with water to produce acids.
