Atom Parts
This is at the center of every atom
The Nucleus
Which part of the periodic table identifies an atoms weight and can be used to figure out the number of neutrons in an atom?
B) the columns
C) the atomic mass
D) the group
This group is made up of semi conductors (elements that show properties of both metals and nonmetals) that allow for computer chips to exist.
Metalloids
Everything that can be touched, felt, smelt, heard
Matter
What are the three states of matter
Solid
liquid
gas
These are found in the nucleus of an atom and carry a (+) charge
Proton
Which part of the periodic table tells you how many electrons are in the outer shell of an atom
A) the rows
B) the columns
C) the atomic mass
D) the group
B) the columns
This group has only 1 electron in it's outer shell and reacts with water explosively.
Alkali Metals
If two elements combine in a way that is One new thing (like hydrogen and oxygen combining into H2O), what do we call that?

precipitation
condensation
evaporation
freezing
melting
deposition
sublimation
evaporation
These circle around the nucleus of every atom in a cloud of constant motion. They also carry a (-) charge.
Electrons
Which part of the periodic table tells you how many electron shells or levels that element has.
A) the rows
B) the columns
C) the atomic mass
D) the group
A) the rows
This group has a full outer shell and reacts with nothing.

Deposition
This atomic part is found in the nucleus but has a neutral charge and add mass to an element.
Neutron
Which part of the periodic table organizes the chart by traits that elements share in common
A) the rows
B) the columns
C) the atomic mass
D) the group
D) Groups
This group of elements missing 1 electron from their outer shell is made of reactive gases that can form some toxic substances.

What do we call an atom when it has an unusual number of Neutrons?
Isotope
The amount of this atomic part in an element is always the same as the atomic number of an element.

They are radioactive and rare

What do we call it when an element gives away electrons (- charge) or a takes electrons (+ charge)
An ION
Could be a positive charge or a negative charge
