Metal/Non-Metal
Elements with this classification are malleable and can conduct electricity easily.
What are metals?
In a diatomic molecule, electronegativity values will be the same, causing the molecule to have this distribution of charge.
What is non-polar (or equal)?
For most elements, an atom requires this many valence electrons in order to be stable.
What is eight?
Periods categorize elements based on electron orbitals, and are oriented in this direction on the periodic table.
What is horizontal?
The periodic table contains this many groups.
What is 18?
Carbon, found in all organic materials, would be classified as under this category.
What are non-metals?
In a strong acid, this element has a lower electronegativity than the element it bonds with, causing it to form positively charged ions when in solution.
Who is Hydrogen?
An electron in the third orbital will have a greater amount of this than an electron in the first orbital.
What is energy?
This element in the first period was partially responsible for the explosion of the Hindenburg, although never held liable in a court of law.
Who is hydrogen?
This Russian Chemist with a fun name to say is credited with the creation of the periodic table.
Who is Dimitri Mendeleev?
This stable non-metal can be found in everything from children's balloons to medical imaging equipment.
What is helium?
This element is the valedictorian of Electronegativity, rocking a 4.0.
Who is Fluorine?
An excited atom with the electron configuration of 2-7-4 would have this as it's ground state.
What is 2-8-3?
This crew just needs to obtain one last electron before they'll be stable.
What are the halogens?
This number is unique to each element, and indicates how many protons it has.
What is the atomic number?
This characteristic of metal means that it can be drawn into wires.
What is ductile?
In table salt, this element will wear the extra electron in the relationship, taking on a negative charge.
Who is chlorine?
A sodium atom has a configuration of 2-8-1, but would be less reactive after bonding with a non-metal and taking on this electron configuration.
What is 2-8?
This non-reactive group is too esteemed to interact with any commoners.
What are the Noble Gases / Group 18?
The atomic mass of this particular isotope is defined as exactly 12 amu.
What is Carbon-12?
The indecisive elements that make up this classification form a staircase-like pattern on the periodic table
What are semi-metals/metalloids?
This energy value that shows the energy required to remove an electron, tends to be higher in more electronegative elements.
What is ionization energy?
Carbon has 4 of these, so it often must form 4 bonds to be stable, making it quite versatile in constructing molecules.
What are valence electrons?
Group 1 elements are commonly stored in oil, because they are so reactive that they will even react with this.
What is oxygen (air) / water?
The top right corner shows possible values for this, which is important in redox reactions.
What are oxidation numbers/states?
