Physical Science Chapter 19
any of several chemical elements that are usually shiny solids that conduct heat or electricity and can be formed into sheets etc.
ability of metals to be hammered or rolled into thin sheets
different forms of the same element having different molecular structures
a molecule that consists of two atoms of the same element
a term used to describe a material that can be pulled out into a long wire
occurs because electrons move freely among a metals positively charged ions and explains properties such as ductile and the ability to conduct electricity.
elements that have characteristics of metals and nonmetals
element that usually is a gas or brittle solid at room temperature, is not malleable or ductile, is a poor conductor of heat and electricity, and typically is not shiny
element such as radium whose nucleus breaks down and emits particles and energy
compound formed when negative ions from an acid combine with positive ions from a base
a substance that can conduct electricity under some conditions
a change directly from the solid to the gaseous state without becoming liquid
elements in groups 3-12 of the periodic table that occur in nature as uncombined elements and include the iron triad and coinage metals
elements having more than 92 protons
