Periodic Table 1
The modern periodic table is organized according to this.
What is atomic number?
The most stable, non-reactive group of elements that have a full outer shell of electrons are known as these.
What are noble gases?
The horizontal rows of the periodic table are called this.
What are periods?
The vertical columns of the periodic table are called this.
What are groups?
Non-metals form this type of ion.
What are anions?
Mendeleev's periodic table was organized according to this.
What is atomic mass?
Metals form this type of ion.
What are cations?
This class of elements are brittle and poor conductors of heat and electricity.
What are non-metals?
The elements in the "d" block, (the "middle" of the periodic table) are known as this.
What are transition metals?
Silicon (Si), Boron (B), and Tellerium (Te) are examples of this class of elements.
What are metalloids?
This class of elements are good conductors of heat and electric current.
What are metals?
The size of an anion compared to its elemental counterpart.
What is bigger?

What is decrease across a period, and increase down the groups?
The trend for ion size going across a period (from left to right) and down a group.
What is decrease across a period, and increase down a group?
The elements in the "f" block (at the bottom of the periodic table) are known as this.
What are inner transition metals?
The size of a cation compared to its elemental counterpart.
What is smaller?
The "s" and "p" blocks (Groups 1-2 & 13-17, or Groups 1A-7A) of the periodic table are referred to as this class of elements.
What are representative elements?
