colour, lustre, melting point, boiling point, hardness, malleability, ductility, crystal shape, solubility, density are examples of these
bawah - burn, air, water, acid and heat are all ways in which a substance can interact
of the same kind; uniform in composition throughout, appears like one (also called a solution)
occurs when two or more substances react and create new substances, a change in colour, odour, light given off, formation of a gas or solid are ways to tell
Most reactive metals on periodic table. Very reactive to water and air. Group 1 on table.
Electron Shell Model - electrons orbit the nucleus in shells and each shell holds a certain amount of electrons.
Group 17 on periodic table. Most reactive non-metals. Chlorine is a well known one from this group.
Group 18 on periodic table. These elements do not react with any other element on the periodic table as their valence shell is full of electrons.
Are all located on the left of the staircase. Properties of metals include: conduct electricity, shiny, malleable, ductile.
Are all located on the right of the staircase. Properties include: can be solid or gas, dull and brittle.
Are a unique set located near the staircase. These elements can display properties of both metals and non-metals.
The father of our modern day periodic table. Arranged elements in order of increasing atomic mass and left blanks for the undiscovered elements at the time.
