Organization
This group on the periodic table is reactive and is not found in pure form around the Earth. It must be extracted by a Scientist. (group number and name)
How many electrons are in Potassium?
19
What is the charge, purpose, and location of a Proton
Positive, Atom Identification, In Nucleus
Where on an element key can you find the number of Protons?
Top center/ top left
What scientist is credited with organizing and setting up the periodic table?
Mendeleev
This group is found naturally throughout Earth, they are reactive but must be slower than their neighboring group (group number and family name)
Group 2: Earth Metals
How many neutrons are in Sodium
12
What is the charge, purpose, and location of a Neutron
Neutral, Holding atom together, Nucleus
Where can you find the total number of protons and Neutrons?
Bottom of element key, under name
What family of elements is known for reacting with other elements to create salts?
Halogens
This family of elements all has a valence electron in the F orbital. Half are extremely radioactive, while the other half are not.
F-block: Lanthanides and Actinides
How many Neutrons are in Og
176
What is the charge, purpose, and location of a electron
negative, Bonding, Electron orbital
Where on a periodic table can you find the Noble gases?
What does AMU stand for?
Atomic Mass Units
This family of elements contains the elements that make up 96% of your body
Other non-mentals (Hydrogen, Oxygen, Nitrogen, Carbon)
If you were assigned a random element that has 72 protons, 72 electrons, and 107 Neutrons. What is the Atomic weight? (rounded answer)
179
What region of the atom takes up the most space?
Electron cloud/ Orbital
Where in an atom will you find the subatomic particle that determines its bonding ability
Electron Orbital
What is the mass of an electron?
1/ 1836 amu
What are the 7 elements that make up the Metalloids?
Boron (B), Silicon (Si), Germanium (Ge), Arsenic (As), Antimony (Sb) Tellurium (Te), Polonium (Po)
What is the AVERAGE atomic mass of the unknown elements? (rounded)
291
What are the characteristics of Metalloid? (three characteristics)
Brittle, have Luster, and are Semiconductors
What family does the element with the most mass live?
Unknown (Oganesson) Og
What family of elements has to be stored in special fluids and gases? AND Why do they need to be stored in this special way?
Alkali metals, because they will react with things that are suspended in our air, like water and nitrogen
