Study about Elements and Compounds | Halogens characteristics,reactivity series of halogens. Just because of this difference the inner core, there are changes in both physical and chemical properties of the elements. Four major factors affect reactivity of metals: nuclear charge, atomic radius Group 1 metals are very reactive metals. The noble gases (historically also the inert gases; sometimes referred to as aerogens[1]) make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. The halogens are a series of non-metal elements from group 17 of the periodic table (formerly VII). Sections below cover the trends in atomic radius, electronegativity, electron Get your answers by asking now. Transition Metals The lanthanides (rare earth) and actinides are also transition metals. The real problem was the lanthanoids. These are all transition metals and chromium, molybdenum and tungsten are refractory metals. Its members are chromium (Cr), molybdenum (Mo), tungsten (W), and seaborgium (Sg). The six naturally occurring noble gases are helium (He), neon … This page discusses the trends in the atomic and physical properties of the Group 7 elements (the halogens): fluorine, chlorine, bromine and iodine. They all show the same chemical properties. These trends can be predicted merely by examing the periodic table and can be explained and understood by analyzing the electron configurations of the elements. The periodic table arranges the elements by periodic properties, which are recurring trends in physical and chemical characteristics.
