The three classes of elements are these.
What are metals, nonmetals, metalloids?
An atom with a completely full outer most (valence) energy level is this.
What is unreactive?
Elements in the same group share these characteristic
What are chemical and physical properties?
The noble gases share this characteristic with regard to their atomic structure.
What are full electron orbitals?
The electrons in the outer energy level are called this.
What are valence electrons?
The electrons involved in chemical reactions are these.
What are valence
Mendeleev organized the elements of his periodic table according to this.
What is increasing atomic mass?
The reactive elements in group 2 are known as this.
What are alkali earth metals?
The vertical columns of the periodic table
groups/families
These metals are the most reactive
Alkali metals
These are the properties of nonmetals.
What are brittleness, low boiling/melting points, dull, and are good insulators?
Group 18 elements are extremely nonreactive nonmetals known as this.
What are noble gases?
Extremely reactive elements in group 1 have only 1 valence electron and are known as this.
What are alkali metals?
Nonmetals form this type of ion.
What are anions or negatively charged atoms?
These metals are the second most reactive.
Alkali Earth metals
This class of elements have properties of both metals and nonmetals.
What are metalloids?
The first energy level/shell/orbital location is
What is closest to the nucleus?
The process of atoms joining together by sharing electrons
What is covalent bonding?
These metals contain familiar metals such as gold, iron, and copper
Transition metals
These elements, also known as inert gases, tend to be nonreactive
Noble gases
