metals and non metals
metals and non metals are seperated by ladder
periodic table
atom
Dmitri Mendeleev was a russian chemist who created the first periodic table
He left gaps in it for elements that had yet to be discovered
instuments are of alloys eg:brass
An ion is a charged atom
An atom becomes charged if it gains or loses on electron
bohr model is a the way an element is explained
atomic number is the smallest number
electrons =number of dots on outer shell
neucleus =outer shell

electrons=no. of dots on outer shell
ionic bonding is when atoms gives other atom electron
alloys=mixture of two metals
lustrous=shiny
malleable =can be beaten into different shapes
no.of protons=electrons
ductile =can be stretched into wires
insulator =does not let heat pass through them
conductor =lets heat pass through them easily
