Structure of Matter
This is anything that has mass and takes up space
Matter
The smallest unit of an element that has properties of that element
Atom
This is a group of elements that conduct heat/ electricity, have luster and are flexible
metals
The number of protons in an atom is called
atomic number
Each element has a one –two letter of these to identify them on the table
symbol
Particles are arranged close together and organized in this
Solid
This is made up of two or more elements
compound
Ability to allow materials to transmit heat/electricity
conductivity
The center of an atom is called this
nucleus
This number on the element’s box includes a combination of the number of protons and neutrons
atomic mass
The measure of the amount of matter in an object
mass
This property can be observed/measured without changing the kind of matter
physical properties
The gradual wearing away/rusting of metal
corrosion
Inside of a nucleus lives these two objects
protons and neutrons
There are seven-eight of these elements on the table that are in a “stair like” pattern
metalloids
This tool measures mass
Pan Balance
Fizzing and burning are examples of this type of property
chemical
The periodic table is set up by these three descriptions
metal/non metal/metalloid
These have no electric charge
neutrons
The periodic table is organized by if it’s a metal/metalloid/non-metal as well as in numerical order by its
atomic number
The upward “push” of a liquid or gas on an object
buoyancy
This is a particle that contains more than one atom joined together
molecule
This category of metal have some properties of metals and some of non-metals
metalloids
Hydrogen and Oxygen
There are more of this category in the periodic table than any other
metals
