elements which can form a positive ions when they react, they are found on the left of the periodic table
what are non-metals?
elements that generally dont form positive ions when they react, they are found on the top right of the table
why do metals lose electrons when they react?
-as they either have less electrons to remove(as they are to the left of the table) or the have lots of electron shells meaning a weaker attraction to the nucleus(as they are at the bottom of the periodic table), this means it takes less energy to lose electrons so the element reacts to form positive ions with a full outer shell
why do non-metals gain electrons when they react?
they have lots of electrons to remove to have a full outer shell(as they are further to the right)and they have a strong attraction to the nucleus(as the are at the top of the periodic table) this means it’s easier for them to share or gain electrons to get s full outer shell
properties of metal?
malleable, ductile, good conductor of heat and electricity, high boiling and melting points
properties of a non-metal?
brittle, poor conductor of heat and electricity, low melting point, aren’t always solid at room temperature
