Chemistry Journal Entry 4

We actually started on a new topic, " Elements, Compounds, and Mixtures ". We learnt the differences between a metal and a non-metal and a metalloid.  

Differences between metal and nonmetal

1. A metal is shiny and lustrous while a non-metal is dull. 
2. A metal is a solid while a non-metal is usually a gas or a liquid. 
3. A metal is malleable, sonorous and ductile while non-metals are brittle( if it is a solid). 
4. Metals usually have a high melting and boiling points while non-metals usually have low melting and boiling points.
5. Metals are good conductors of heat and electricity while non-metals are the opposite. 

Metalloids usually exhibit both properties of a metal and a non-metal and therefore,they are called METALLOIDS. 

What you see here is a a Periodic Table of Elements. Guess what? There's one element named einsteinium which is named after Albert Einstein. So interesting! The Periodic Table is arranged according to increasing proton numbers from left to right.
