What is the group or the family?
This number on the periodic square tells the number of protons in an atom.
What is the atomic number?
The number of electrons in the outer orbit of an atom.
What is a valence number?
The group of metals that are the most reactive.
What is Alkali metals?
These elements can be dull, have poor conductivity, and are usually brittle.
What are nonmetals?
The name of the rows in the periodic table.
What is a period?
This number on the element square tells the how many neutrons and protons are in the atom.
What is the atomic mass?
The group that has one valence electrons.
What is group 1 or the Alkali metals?
