What is lithium's state of matter? What is the state of matter of water? What state of matter are most metals? What are the physical and chemical properties of halogens? What state of matter is neon? Is sodium a solid, liquid, or gas?
Lanthanum is a malleable, ductile, and soft metal. It is obtained from monazite and bastn盲site and is mainly used as an alloying element and in lighter flints. It belongs to Group 3 of the Periodic Table: Physical Properties Chemical Properties Lanthanum oxidizes rapidly when exposed to air....

This chapter will focus primarily on the selection criteria, production, and the nuclear, physical, and chemical properties of therapeutic radionuclides, including those that are currently being used, or studied and evaluated, and those that warrant future investigations. Various scientific and practical...
2 Elements in the same group of the Periodic Table often show trends in physical properties and similarities in chemical properties.(a) Name a group in the Periodic Table and briefly describe a trend in a physical property shown on moving down this group.nameof groupthekametals Densityincreases...
In addition, the two-dimensional 1H-13C HS-QC was conducted for both liquid and concentrated tar samples to determine differences in their chemical composition. Torrefaction tar viscosity was characterised using a rheometer. The differences in physicochemical properties of torrefaction tar were correlated...
