What are the physical and chemical properties of sodium chloride?
Sodium chloride, a white crystalline solid, contains a density of 2.165 g/mL, the melting point of 801 °C, and the boiling point is about 1,413 °C. It is also available as aqueous solutions with different concentrations, which are known as saline solutions.
What controls the chemical and physical properties of elements?
Atomic number An element and its place within the periodic table are derived from this concept. When an atom is generally electrically neutral, the atomic number will equal the number of electrons in the atom, which can be found around the core. These electrons mainly determine the chemical behaviour of an atom.
What elements does sodium react with?
Sodium metal reacts vigorously with all the halogens to form sodium halides. So, it reacts with fluorine, F2, chlorine, Cl2, bromine, I2, and iodine, I2, to form respectively sodium(I) bromide, NaF, sodium(I) chloride, NaCl, sodium(I) bromide, NaBr, and sodium(I) iodide, NaI.
What are 2 chemical properties of sodium?
It’s a soft metal, reactive and with a low melting point, with a relative density of 0,97 at 20ºC (68ºF). From the commercial point of view, sodium is the most important of all the alkaline metals. Sodium reacts quickly with water, and also with snow and ice, to produce sodium hydroxide and hydrogen.
Is sodium a good conductor of electricity?
Pure sodium (Na) is a good conductor of electricity because the 3s and 3p atomic bands overlap to form partially filled conduction bands.

Which of the following is a physical property of sodium chloride?
Physical properties: Sodium chloride is a white crystalline solid with a density of 2.16 g/mL, and a melting point of 801 °C. It is also available as aqueous solutions of different concentrations, called saline solutions. Chemical properties: Sodium chloride is readily soluble in water and other polar solvents.
What is the chemical property of an element?
A chemical property is a characteristic of a substance that may be observed when it participates in a chemical reaction. Examples of chemical properties include flammability, toxicity, chemical stability, and heat of combustion.
What controls the physical properties of elements?
The biggest contributor to determining physical properties is the number of electrons and the number of empty quantum states (“slots,” because I forget the actual word) in the outer electron shell.
