Who was Democritus
one of the first to introduce the idea of the atom and many people believed Aristotle before him. he used the greek word atomos
He was a famous philosopher who believed that matter was composed of four elements earth, fire, air, and water his theory was the most common for 2000 years
he created the first theroy that was accepted that wasn't Aristole's theory and his theory lead J.J Thompson to make the plum pudding model
who was J.J Tompson
He was a famous philosopher who believed that matter was composed of four elements earth, fire, air, and water his theory was the most common for 2000 years
one of the first to introduce the idea of the atom and many people believed Aristotle before him. he used the greek word atomos
He conducted the plum pudding model based off of Dalton's theory and proposed that electrons were embedded inside a positive charge
What is Li-Fr
Alkaline metals
Alkaline Earth metals
Post-transition metals
Halogens
Alkaline metals are....
soft malleable and ductile good conductors of heat and electricity that are very reactive and have low melting and boiling points they want to give away one electron
Soft malleable and ductile fairly reactive found In earth's crust want to give away two electrons
have both properties of metals and non-metals used as SEMI conductors lack metallic luster
what is He-Og
acidities
lanthanides
noble gasses
other non-metals
what are noble gasses
Soft malleable and ductile fairly reactive found In earth's crust want to give away two electrons
Very stable gassess and unreactive colorless but will light up when an electric charge is sent through them
most are solid but nitrogen and oxygen are gases bad conductors of electricity tend to want to gain electrons
what is Co-Lu
other non-metals
actinides
Lanthanides
metalloids
What is a transition metal
majority of the periodic table is malleable and ductile and good conductors of heat and electricity generally hard and with a high density and less reactive than groups one and two ex: copper gold
very reactive non-metals at room temperature exist as soilds liquids and gasses
soft malleable and ductile good conductors of heat and electricity that are very reactive and have low melting and boiling points they want to give away one electron
which are lathanides
Lu-Fr Soft malleable and ductile fairly reactive found In earth's crust want to give away two electrons
Ce-Lu has many traits similar to metals and is widely used in alloys
B-Po has both properties of metals and non-metals used as SEMI conductors lack metallic luster
what are post-transition metals
generally solid ductile and malleable relatively high density
have both properties of metals and non-metals used as SEMI conductors lack metallic luster
soft malleable and ductile good conductors of heat and electricity that are very reactive and have low melting and boiling points they want to give away one electron
Who was Neil Bohr
He was a famous philosopher who believed that matter was composed of four elements earth, fire, air, and water his theory was the most common for 2000 years
Added energy levels to the atoms and created the Bohr model
He was a famous philosopher who believed that matter was composed of four elements earth, fire, air, and water his theory was the most common for 2000 years
What are metalloids
have both properties of metals and non-metals used as SEMI conductors lack metallic luster
soft malleable and ductile good conductors of heat and electricity that are very reactive and have low melting and boiling points they want to give away one electron
Lu-Fr Soft malleable and ductile fairly reactive found In earth's crust want to give away two electrons
what are other non-metals
Mostly solids and but nitrogen and oxygen are bad conductors of heat and energy
Lu-Fr Soft malleable and ductile fairly reactive found In the earth's crust want to give away two electrons
La-Lu has many traits similar to metals and is widely used in alloys
Halogens are
widely used in alloys have many traits of metals
Very reactive non metals at room temp can exist at solids gasses and liquids
unstable and reactive and nuclear
