Is lithium physical or chemical?
Lithium (from Greek: λίθος, romanized: lithos, lit. ‘stone’) is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid element.
What is the 3 in lithium?
Lithium is an alkali metal with the atomic number = 3 and an atomic mass of 6.941 g/mol. This means that lithium has 3 protons, 3 electrons and 4 neutrons (6.941 – 3 = ~4). Being an alkali metal, lithium is a soft, flammable, and highly reactive metal that tends to form hydroxides.
What are lithium physical properties?
Lithium has a melting point of 180.54 C, a boiling point of 1342 C, a specific gravity of 0.534 (20 C), and a valence of 1. It is the lightest of the metals, with a density approximately half that of water. Under ordinary conditions, lithium is the least dense of the solid elements.
What are 5 chemical properties?
A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.
What element has properties like lithium?
Lithium comes in Group 1 of Modern periodic table. Other elements of the same group are Sodium(Na), Potassium(K), Rubidium(Rb), Cesium(Cs) and Francium(Fr). These are called alkali metals. Lithium and Magnesium shows similar chemical properties because of Diagonal relationship.
What physical property of lithium is seen when it reacts with water?
floats
When lithium is added to water, lithium floats. It fizzes steadily and becomes smaller, until it eventually disappears.
What is the texture of lithium?
Lithium is a body-centered-cubic (bcc) metal, and thus its sheet texture is very similar to other bcc metals (40).
What are the physical properties of beryllium?
Physical properties
Beryllium is a steel gray and hard metal that is brittle at room temperature and has a close-packed hexagonal crystal structure. It has exceptional stiffness (Young’s modulus 287 GPa) and a melting point of 1287 °C.
Is lithium a malleable?
In the form of a simple element, lithium, is a malleable, soft, light metal of a silvery color.

Why is lithium atomic number 3?
Lithium is the element that is atomic number 3 on the periodic table. These means each atom contains 3 protons. Lithium is a soft, silvery, light alkali metal denoted with the symbol Li.
What are lithium uses?
Lithium is used to treat and prevent episodes of mania (frenzied, abnormally excited mood) in people with bipolar disorder (manic-depressive disorder; a disease that causes episodes of depression, episodes of mania, and other abnormal moods).
Is lithium a mineral?
Lithium was first discovered in the mineral petalite. Lepidolite and spodumene are other common minerals which contain lithium. Commercial quantities of these three minerals are in a special igneous rock deposit that geologists call pegmatite.
What are Silicons properties?
In this chapter, properties of silicon are explained in detail. Silicon is an abundant element found in the Earth’s crust in various compounds.

Is boiling point a physical property?
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
What is the odor of lithium?
Lithium is a soft, silver to grayish-white (or yellow if exposed to air), odorless metal, crystalline mass or powder.
What are 3 physical properties?
Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.
What are chemical and physical properties?
The general properties of matter such as color, density, hardness, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties.
