A heavy element with a single valence electron, it has the highest equivalent weight of any element. The elements in group 1 are called the alkali metals. Like all alkali metals, lithium is highly reactive and flammable, and is stored in mineral oil.
Explain your answer.
... 1 Physical. This is because francium is below caesium in the
Physical and chemical properties Until very recently, there was not enough francium to permit a study of its properties. Uses of Francium: None; Additional Notes: Francium is never encountered normally, however, handling it would be very dangerous as it is a powerful source of alpha radiation. Many metals are transition metals.Our team of exam survivors will get you started and keep you going.is a vertical column on the far left of the,Group 1 is on the left-hand side of the periodic table,The alkali metals share similar physical and chemical.. EnvironmentalChemistry.com. Francium Menu.
Use this information to describe how melting point changes in group 1.Going down group 1, the melting point decreases.Use the information in the table to predict the melting point of francium, Fr. It exists only in short-lived radioactive forms. Under standard conditions, it is the lightest metal and the lightest solid element. Francium (Fr), heaviest chemical element of Group 1 (Ia) in the periodic table, the alkali metal group. Its melting point is 28.5°C (83.3°F). Explain your answer.The melting point of francium will be around 27°C. This WebElements periodic table page contains physical properties for the element francium 1 Melting Point. Physical properties Cesium is a silvery-white, shiny metal that is very soft and ductile. Ductile means capable of being drawn into thin wires. periodic table, so it should have a lower melting point, and the difference in melting point decreases going down from one element to the next.Predicting chemical reactions - OCR Gateway,Predicting and identifying reactions and products,Home Economics: Food and Nutrition (CCEA).Read about our approach to external linking. Common chemical compounds are also provided for many elements. Francium is an alkali metal whose chemical properties mostly resemble those of caesium. They are low enough for the first three (lithium, sodium and potassium) to float on water.The table above shows the melting points of five alkali metals. The alkali metals are the elements in Group 1. Physical properties of the alkali metals Group 1 is a vertical column on the far left of the periodic table . properties of Francium (Fr) like atomic, mechanical, electrical, thermal and magnetic properties. It melts easily in the heat of one's hand, but should never be handled that way! Barbalace, inc., website development,Plagiarism, Copyright Infringement and Fair Use.
