Developing the Periodic Table
Who is Dmitri Mendeleev?
These are found along the right side of the periodic table.
What are nonmetals?
This is the interaction/force between the nucleus and the electrons in an atom.
What is attraction?
This is the periodic trend that represents roughly the size of an atom.
What is atomic radius?
This is what happens to ionization energy as you move from top to bottom along a group.
What is decreases?
This was the revolutionary difference of Mendeleev's periodic table that other scientists had not previously done.
These are the horizontal rows of elements that have repeating patterns, but don't share the same properties.
What are periods?
DOUBLE JEOPARDY: This is the name of the way electrons are arranged in space in an atom.
What is electron configuration?
DOUBLE JEOPARDY: This is responsible for the periodic properties of elements & plays a role in periodic trends.
What is nuclear charge?
This is the ability of an atom to attract and bind to the electrons of another atom.
What is electronegativity?
Mendeleev organized the elements based on atomic mass, except for when these took priority.
What are similar properties?
What is a zigzag?
This happens to the force between electrons and the nucleus when electrons are farther away.
What is it gets weaker?
This is the energy required to remove an electron from an atom's outer shell.
What is ionization energy?
This is the reason for elements in group 17 wanting to gain one more electron, and therefore responsible for a lot of the periodic trends we see.
What is a full outer shell?
DOUBLE JEOPARDY: These are what we focus our attention on in class, by cutting out the transitions metals in the middle of the table.
What are the main group elements?
This is the law that helps predict the strength of the force between electrons and the nucleus.
What is Coulomb's Law?
What is decreases?
What is a nonmetal on the left side of the table?
DOUBLE JEOPARDY: This is what happens when valence electrons experience the shielding effect.
What is repulsion from core electrons?
Regarding electron affinity, what happens to the energy when an atom gains an electron?
What is energy is released?
