group two on the periodic table.
where are the Alkaline Earth metals located on the periodic table?
metalloids have properties of both ________ and _______
Metals and nonmetals.
where are the noble gases on the periodic table?
they are located in the very last group on the right of the periodic table.
between the metalloids and the noble gases.
where is the location of the nonmetals
Why must alkali metals be stored under oil?
to prevent reaction with air due to their high reactivity.
How many valence electrons do each have?
Two valence electrons
What is typically the appearance of metalloids?
metallic
helium

what kind of conductors are nonmetals?
nonmetals are very poor conductors of heat and electricity.
sodium

the term Metalloid originally referred to ______.
nonmetals
except when under extreme conditions, noble gases are typically ________.
very unreactive
nonmetals exist in what states of matter?
solids and gases
what is the oldest use of sodium?
selling to Roman soldiers in ancient times.
compounds of this has been used since prehistoric times.
they are too brittle.
Because the valence electrons in the larger noble gases are farther away from the nucleus and are therefore not held as tightly together by the atom.
Why does the ionization decrease along the family?
easily shares and gains electrons.
What is the ionization energy like for nonmetals?
