What are the properties of each element?

Chemical properties

• Atomic number. The atomic number indicates the number of protons within the core of an atom.
• Atomic mass. The name indicates the mass of an atom, expressed in atomic mass units (amu).
• Electronegativity according to Pauling.
• Density.
• Melting point.
• Boiling point.
• Vanderwaals radius.
• Ionic radius.

What is the atomic no of zinc?

30
Zinc/Atomic number

What makes each element unique?

Each element has its own unique properties. Each contains a different number of protons and neutrons, giving it its own atomic number and mass number. The atomic number of an element is equal to the number of protons that element contains.

What are carbons properties?

The physical and chemical properties of carbon depend on the crystalline structure of the element. Its density fluctuates from 2.25 g/cm³ (1.30 ounces/in³) for graphite and 3.51 g/cm³ (2.03 ounces/in³) for diamond. The melting point of graphite is 3500ºC (6332ºF) and the extrapolated boiling point is 4830ºC (8726ºF).

What are the chemical properties of francium element?

What is Francium – Chemical Properties of Francium – Symbol Fr Element Francium Atomic Number 87 Symbol Fr Element Category Alkali Metal Phase at STP Solid

What is the half life of francium metal?

Francium is highly radioactive. Francium is a heavy, unstable, radioactive metal with a maximum half-life of only 22 minutes. It has a low melting point (27 °C, 81 °F) and, if enough of it could be accumulated, it would be liquid in a warm room. Francium is the second rarest element in the Earth’s crust, next to astatine.

How big is the atomic radius of francium?

The atomic radius of Francium atom is 260pm (covalent radius). It must be noted, atoms lack a well-defined outer boundary. The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus.

How did francium get its name on the periodic table?

Radioactive alkali metal with short lived nuclides. Note: this data represents naturally occuring levels of elements in the typical human, it DOES NOT represent recommended daily allowances. Named after France. Formed by decay of actinium. Chemical properties similar to cesium. Decays to radium or astatine.
