L2: metals and non-metals. Flashcards
Where are metals on the periodic table?
They are on the left and centre of the periodic table
Where are non metals on the periodic table?
Mostly on the right, a staircase shaper from carbon to iodine, then down to astatine, then to radon, and all in between are non metals
how do metalloids behave?
sometimes like metals and sometimes like non metals, they are located as a staircase from boron to polonium
what are three properties of metals?
They are flexible (malleable and ductile), good electrical conductors, good heat conductors.
What does ductile mean?
u r able to make thin wire out of it.
what does malleable mean?
can be shaped without breaking
What r three properties of non metals?
Good heat insulator, good electrical insulator, brittle.
What does brittle mean?
Hard but can easily crack/break
