Column One
What 3 particles make up an atom?
Protons, Neutrons, Electrons
Where are the protons and neutrons located?
In the nucleus of an atom.
Who was the first person to come up with the idea of an atom?
Democritus
What scientist created the model of an atom with energy levels?
Niels Bohr
Why are electrons not included in the mass of the atom?
They are negligible compared to the mass of the protons and neutrons/ The mass of the electron is too small.
Who is recognized as the architect of the periodic table?
Dimitri Mendeleev
How are the elements arranged in the periodic table?
By atomic number/ increasing atomic number/ from left to right
In terms of the charge of the atoms, in what state are the atoms in the periodic table?
The atoms are neutral/ protons and electrons equal the same amount.
What do the groups on the periodic table represent?
The number of valence electrons.
What is the maximum number of of electrons that can be found on the valance shell?
8 electrons/ 8 valence electrons/ 8.
What family is group 17 on the periodic table?
Halogens
What family is recognized to be the most stable and non reactive?
Noble Gasses
What is one characteristic of non metals on the periodic table?
Bad conductors/ nto malleable or ductile/ very brittle when in a solid state/ less dense than metals.
Elements in group 17, will need to gain or lose electrons?
Gain one electron/ gain one to complete 8 on the valence shell/ take one to complete a stable octet.
What family on the periodic table display properties of both metals and non-metals?
Metalloids.
This element is present in laughing gas.
Nitrogen in the form of nitrous oxide.
The name of this element comes from the Greek word "argos" meaning "lazy" or "inactive.
Argon
Name one element that was named after a planet.
Uranium, plutonium, neptunium.
Which is the only letter that does not appear in the periodic table, either as a symbol or in an element name?
Letter J.
The alchemist Hennig Brandt in 1669 tumbled across this element while conducting experiments with urine.
Phosphorus.
It is artificially produced, and its most stable isotope has a half-life of about 80 milliseconds.
Tennessine.
Indigenous people of South America for metalcraft, which element comes from the Spanish word for “silver”?
Platinum
Because it is highly durable and resistant to corrosion, this element was used by the Romans to make water pipes as well as coins and cooking utensils. By the time of Augustus Caesar, poisoning had become an issue in Rome because of this element.
Lead
Only metal that is a liquid at room temperature
Mercury
Why are Magnesium fires hard to put out?
Because they can burn through nitrogen, carbon dioxide and water.
