Question

Сравнить строение и свойства атомов натрия, хлора, аргона.Помогите, пожалуйста!

Answer 1

Натрий- щелочной металл, в последней оболочке 1 электрон, очень активный металлхлор - неметалл, галоген, в оболочке  7 электронов, активный неметалл, хорошо реагирует со многими веществами, молекула состоит из двух атомоваргон-инертный газ, в оболочке 8 электронов, плохо рекгирует с веществами

Answer 2

Comparing the Structure and Properties of Sodium, Chlorine, and Argon

Atomic Structure: - Sodium (Na) has an atomic number of 11 and an electron configuration of 1s2 2s2 2p6 3s1. - Chlorine (Cl) has an atomic number of 17 and an electron configuration of 1s2 2s2 2p6 3s2 3p5. - Argon (Ar) has an atomic number of 18 and an electron configuration of 1s2 2s2 2p6 3s2 3p6.

Physical Properties: - Sodium: - Sodium is a soft, silvery-white, highly reactive metal. - It has a melting point of 97.79°C and a boiling point of 882.9°C.

- Chlorine: - Chlorine is a greenish-yellow gas at room temperature and pressure. - It has a melting point of -101.5°C and a boiling point of -34.04°C.

- Argon: - Argon is a colorless, odorless, and non-reactive gas. - It has a melting point of -189.3°C and a boiling point of -185.9°C.

Chemical Properties: - Sodium: - Sodium readily forms a +1 cation by losing its single valence electron. - It reacts vigorously with water to produce sodium hydroxide and hydrogen gas.

- Chlorine: - Chlorine is a highly reactive nonmetal and readily forms a -1 anion by gaining an electron. - It is used in the production of a wide range of chemical products, including plastics, solvents, and pesticides.

- Argon: - Argon is a noble gas and is chemically inert, meaning it does not readily form compounds with other elements. - It is used in various applications such as welding, lighting, and in the production of semiconductor materials.

Conclusion: In summary, sodium is a reactive metal, chlorine is a highly reactive nonmetal, and argon is an inert noble gas. Their atomic structures and properties differ significantly, reflecting their positions in the periodic table and their respective chemical behaviors.
