WebA horizontal row in the periodic table. The atomic number of each element increases by one, reading from left to right. Block Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). Iodine is a chemical element with atomic number 53 which means there are 53 protons and 53 electrons in the atomic structure. The chemical symbol for Iodine is I. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. The nucleus is composed of protons … Meer weergeven Iodine is a chemical element with atomic number 53 which means there are 53 protons and 53 electrons in the atomic structure.

Web31 jan. 2024 · Nonmetals can be gases (such as chlorine), liquids (such as bromine), or solids (such as iodine) at room temperature and pressure. Most solid nonmetals are brittle, so they break into small pieces when hit with a hammer or pulled into a wire. As expected, semimetals exhibit properties intermediate between metals and nonmetals. Example 2.6. 1 WebThe halogens are the elements that form group 17 of the periodic table. They are reactive nonmetals and include fluorine, chlorine, bromine, and iodine. Halogens are highly reactive non-metals. These elements greatly … WebIodine is a non-metallic, solid element on the periodic table that belongs to the halogen family. This element makes a bold statement with its dark, shiny, gray-blue-black color. It i the heaviest of the stable halogens, and is very volatile, easily forming a purple vapor that can be easily seen. dan pena snowflake test results
