Atoms & Periodic Table
Atomic Theory, Parts of the Atom and the Periodic Table
This scientist coined the term "atom" and said that it was an uncuttable particle.
This scientist said that atoms combine in specific proportions and atoms of the same element were alike.
This scientist created the "plum pudding" model of the atom based on his cathode ray tube experiment.
This scientist said that the center of the atom was positively charged and he coined the term "nucleus" for it based on his gold foil experiment.
This scientist said that electrons travel in definite paths around the nucleus.
These scientists cointed the term "electron cloud"
Schrodinger & Heisenberg
Which subatomic particle has a positive charge, a mass of 1 and is found in the nucleus?
Which subatomic particle is found in the nucleus, has a mass of 1 and has no charge?
Which subatomic particle has a negative charge, no mass and is found outside the nucleus?
The number of total protons in the nucleus is known as this.
The number of protons in addition to the number of neutrons is known as this.
When an atom has a different number of neutrons from its regular atom, it is known as this.
This is the listing of all the elements that are exiting and that have been created.
A regular repeating pattern.
These elements are on the left side of the periodic table, have a small number of electrons in the outer shell, are reactive, ductile, malleable and shiny.
These elements are on the right side of the periodic table, are not shiny, ductile or malleable and are often gases.
These elements sit on the zigzag line of the periodic table and have characteristics of both metals and nonmetals.
A row on the periodic table arranged by increasing atomic number.
A column or family on the periodic table made up of elements who have very similar chemical and physical properties
This is the most abundant element in the universe.
The most reactive metals on the periodic table. They have one electron in the outer level.
These nonmetals have a full outer electron shell and are unreactive or inert.
These metals are the second most reactive elements on the table and have two electrons in the outer most level.
Alkali earth metals
The most reactive nonmetals or salt formers.
These metals form colored solutions in water.
These are the radioactive metals on the periodic table.
