How Did Rolling Ray End Up In A Wheelchair, LOGIN TO VIEW ANSWER. Compare elements on more than 90 properties. Prism Career Institute Transcripts, Rubidium (Rb) is more reactive than strontium (Sr) because strontium atoms must lose more electrons. It is a soft, silvery-white metallic element of the alkali metals group (Group 1). The primary difference between metals is the ease with which they undergo chemical reactions. ... for groups 6A and 7A in the periodic table. Explain. Francium should be the most reactive but it's physically impossible to use since it would vaporise itself with its own radioactivity. Cushion Army. This element is _____. Which element is more reactive than rubidium (Rb)? Cesium is considered the most active metal. Rubidium was discovered (1861) spectroscopically by German scientists Robert Bunsen and Gustav Kirchhoff and named Caesium has physical and chemical properties similar to those of rubidium … The alkali metals form a homogeneous group of extremely reactive elements which illustrate well the similarities and trends to be expected from the periodic classification, as discussed in Chapter 2.Their physical and chemical properties are readily interpreted in terms of their simple electronic configuration, ns 1, and for this reason they have … An element's reactivity is based on how many electron shells it has. Cesium is used in atomic clocks, drilling and in creating optical glass among other highly specialized applications. Examples are Magnesium, Beryllium, Radium, Barium, Calcium, and Strontium. Rubidium's main application is in the glass manufacturing. Elemental rubidium is highly reactive, with properties similar to those of other alkali metals, including rapid oxidationin air. Rubidium is a very soft, ductile, silvery-white metal. So the K is more reactive than calcium and less than rubidium. So, cash Thomas, more habitual. It follows that elements below potassium in the table should be more reactive than potassium is. Okay, because a literal positivity increases down the group and cash. Why are these elements in the same column in the periodic table? Shooter Jennings Dad, Rubidium can be liquid at ambient temperature, but only on a hot day given that its melting point is about 40°C. appeared first on nursingcoursework.org.
