Periodic Table A
The modern periodic table organizes elements according to this.
What is increasing atomic number?
The bond formed between a metal and a nonmetal.
What is ionic bond?
Metals form this type of ion.
What are cations?
The very reactive elements in group 1 are known as this.
What are alkali metals?
The horizontal rows on the periodic table.
What are periods?
The three classes of elements.
What are metals, nonmetals and nonmetals?
The period numbers indicate this.
What is number of energy levels/ electron shells?
The Valence Electrons for Nitrogen Family.
What are 5?
Reason Noble gases are stable.
What is a full outer energy level?
Being shiny, malleable, and conductors are properties of this class of elements.
What are metals?
Electrons that can most easily be lost, gained, and shared.
What are valence electrons?
The reactive elements in group 2 are known as this.
What are alkali earth metals?
