Question

1.а) Расположите элементы в периоде в порядке возрастания их неметаллических свойств. S; Mg; P; Na; AI; Ar; Si; CI. помогите пж!​

Answer 1

Ответ:

Na, Mg, Al, Si, P, S, Cl, Ar

Объяснение:

Все эти элементы располагаются в 3 периоде, а в периоде слева направо увеличивается заряд ядра, следовательно, увеличивается притяжение к ядру валентных электронов и затрудняется их отдача, также происходит увеличение количества валентных электронов, атому для завершения энергетического уровня становится легче принять электроны, а не отдавать их, поэтому происходит усиление неметаллических свойств

Answer 2

Arranging Elements in Increasing Order of Non-Metallic Properties

To arrange the given elements in the period in the order of increasing non-metallic properties, we can refer to the periodic table. The non-metallic properties generally increase from left to right across a period.

1. Sulfur (S): Sulfur is a non-metal located in group 16 of the periodic table. It exhibits non-metallic properties and is known for its distinct odor and yellow color.

2. Phosphorus (P): Phosphorus is also a non-metal and is located in group 15 of the periodic table. It is essential for life and has various allotropes, some of which exhibit non-metallic properties.

3. Silicon (Si): Silicon is a metalloid, which means it has properties of both metals and non-metals. It is located in group 14 of the periodic table.

4. Chlorine (Cl): Chlorine is a non-metal and is part of group 17 in the periodic table. It is a highly reactive element and exhibits typical non-metallic properties.

5. Argon (Ar): Argon is a noble gas and is located in group 18 of the periodic table. Noble gases are known for their non-reactive nature and are considered non-metals.

6. Sodium (Na): Sodium is a metal and is located in group 1 of the periodic table. It exhibits metallic properties and is highly reactive.

7. Magnesium (Mg): Magnesium is also a metal and is located in group 2 of the periodic table. It exhibits metallic properties and is essential for various biological processes.

8. Aluminum (Al): Aluminum is a metal and is located in group 13 of the periodic table. It exhibits metallic properties and is known for its lightweight and corrosion resistance.

Based on the periodic table and the properties of these elements, the order of increasing non-metallic properties in the given period would be: Mg < Na < Al < Si < P < S < Cl < Ar.
