Also used in alloys such as brass, bronze, nickel.

Want to learn more details and data about Zinc (Zn)? Check my Elements Comprehensive List. Standard atomic weight: 65. Zinc Atomic Radius 1.53 State at 20 C Solid Uses Used to coat other metal (galvanizing) to protect them from rusting. Also in solder, cosmetics and pigments.įound in the minerals zinc blende (sphalerite) (ZnS), calamine, franklinite, smithsonite (ZnCO3), willemite, and zincite (ZnO). Based on this information, which of the following diagrams best represents an alloy. Zinc Boiling Point: 907.0C 1664.6F 1180.15 K Critical Temp: C F K Atomic Radius: 1.53 ( Angstrom 10-10 m) Covalent Radius: 1.25. Option d: For ions of same element, the size should decrease with increase in the positive charge. Copper atoms and zinc atoms have the same atomic radius, 135 picometers. Atomic Spectrum of Zinc Zinc Chemical Properties: Zinc Ionization Energies and electron affinity The electron affinity of Zinc is 0 kJ/mol. Atomic Number: 30: Atomic Radius: 139 pm (Van der Waals) Atomic Symbol: Zn: Melting Point: 419.5 ☌: Atomic Weight: 65. Also used in alloys such as brass, bronze, nickel. The atomic size increases from top to bottom in a group. Zinc atomic radius is 142 pm, while it's covalent radius is 131 pm.

Used to coat other metal (galvanizing) to protect them from rusting. This definition has been changed (see Krypton ). In the case of Zinc the covalent radius is 1.25 Å. You see, there is a lot of info about Zinc (beyond an atom's radius) that is actually interesting. In 1927 the International Conference on Weights and Measures redefined the meter in terms of the wavelength of the red cadmium spectral line (i.e. Ok but what is the covalent radius of an atom of Zn? Molecules and atoms have a certain 'size or radius', even Zinc.
