Chapter 19 vocab.

metal element that typically is a hard shiny solid is malleable and is a good conductor of hear and electricity
malleable being able to be rolled or pressed into sheets
ductile ability of metals to be drawn into wires
metallic bonding occurs because electrons move freely among a metals positively charged ions and explains properties such as ductility and the ability to conduct electricity
radioactive element element such as radium whose nucleus breaks down and emits particles and energy
transition element elements in groups 3 through 12 of the periodic table occur in nature as uncombined elements and include the iron triad and coinage metals
nonmetal 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
diatomic molecule a molecule that consist of two atoms of the same element
salt compound formed when negative ions from an acid combine with positive ions from a base
sublimation the process of a solid changing directly to a vapor without forming a liquid
metalloid element that shares some properties with metals and some with nonmetals
allotrope different forms of the same element having different molecular structures
semiconductor materials having conductivity properties between that of metals (good conductors) and nonmetals (insulators) and having controllable conductivity parameters
transuranium element elements ha in more than 92 protons all of which are synthetic and unstable
