Question

Quizplus · Accepted Answer

The three broad categories of elements are metals, nonmetals, and metalloids. Most elements are metals.
In general, metals are located on the left of the periodic table and non-metals are located on the right of the periodic table (with Hydrogen being an exception). Metalloids are make up the stair-shaped block of elements between metals and non-metals.
Strontium (Sr) is in group 2 and is part of the alkaline earth metals.

metallic luster (shiny)
high electrical and thermal conductivity
usually hard solids (mercury is liquid)
usually ductile (capable of being drawn into a wire) and malleable (capable of being hammered into thin sheets)
most have high melting points
readily lose electrons (low electron affinity) to create cations (a positively charged ion)
low ionization energies (does not require a lot of energy to lose an electron)
Properties of metalloids
metalloids have multiple forms
can be made to conduct electricity under special conditions (semiconductors)
Properties of non-metals
usually poor conductors of heat and electricity
often liquids or gases at room temperature and pressure
lack metallic luster (not shiny)
readily gain electrons (high electron affinity)
high ionization energy (takes a lot of energy to lose an electron)
