Is sodium a gas or solid?
Sodium in its pure form is a solid.
When was sodium found?
1807
Sodium/Discovered
Davy discovered sodium in 1807 by isolating it from sodium hydroxide through electrolysis, and in 1811 he gave chlorine its name after unambiguously recognizing it as a pure element — although discovered in 1774 by the Swedish chemist Carl Wilhelm Scheele, chlorine was at the time considered to be a mixture with oxygen …
Why is sodium not found uncombined?
Chemical Properties: Sodium is a very reactive element and is never found in the uncombined state in nature. Sodium has one electron in its outer energy level that is the source of its chemical reactivity. Sodium metal reacts spontaneously with water to give sodium hydroxide and hydrogen gas.

What state of matter is sodium chloride?
solid
NaCl is a solid at room temperature, with a very high melting point (801 °C), similar to the melting points of silver (961.78 °C) and gold (1064.18 °C), although much lower than the decomposition temperature of diamond (3550 °C).
Is sodium a solid element?
Sodium is a chemical element with symbol Na and atomic number 11. Classified as an alkali metal, Sodium is a solid at room temperature.
Where is sodium most commonly found?

Where is sodium found in the body?
Most of the sodium in the body (about 85%) is found in blood and lymph fluid. Sodium levels in the body are partly controlled by a hormone called aldosterone, which is made by the adrenal glands. Aldosterone levels tell the kidneys when to hold sodium in the body instead of passing it in the urine.
Where is sodium discovered?
Sodium was discovered in 1807 by the English chemist Humphry Davy from electrolysis of caustic soda (NaOH). Although sodium is the sixth most abundant element on earth and comprises about 2.6% of the earth’s crust, it is a very reactive element and is never found free in nature.
Why is sodium not found in nature?
Because sodium is extremely reactive, it never occurs in the free state in Earth’s crust.
What are the elements of sodium?

Where is sodium chloride found?
seawater
Sodium chloride (NaCl), commonly known as salt, is one of the most abundant minerals on Earth and an essential nutrient for many animals and plants. It is naturally found in seawater and in underground rock formations.
What are 5 facts about sodium?
Fun Sodium Facts Sodium is a soft, malleable and shiny solid at room temperature. Sodium is less dense than water. Sodium is soft enough to cut with a butter knife at room temperature. Sodium metal reacts with water to produce hydrogen gas. Sodium burns with a bright yellow light. Sodium is the sixth most abundant elements on Earth.
What is sodium’s state of matter at room temperature?
Sodium has a body-centered cubic (bcc) structure. It has a hardness of 0.5 mohs. At room temperature, sodium is found in the form of a solid metallic substance which is very soft to touch. Due to its softness, you can easily cut it with the help of a table knife.
What is the chemical state of sodium?
Chemically, sodium is represented by the symbol Na. Atomic number of sodium is 11 and its atomic mass is 22.98. As the atomic number of sodium suggests, it has only one electron in its outermost orbit or its valency is +1.
What state of matter would sodium hydroxide be?
Sodium hydroxide (NaOH) is a corrosive white crystalline solid that readily absorbs moisture until it dissolves. Commonly called caustic soda, or lye, sodium hydroxide is the most widely used industrial alkali. It is highly corrosive to animal and vegetable tissue.
