The ability of an object to push or pull on another object that has magnetic properties.
magnetism
The smallest unit of an element
atom
List 5 physical properties
magnetism, solubility, texture, color, hardness, elasticity, flexibility, mass, volume, density, buoyancy, states of matter
TRUE or FALSE
an element can be separated into parts
FALSE- smallest unit of matter
The maximum amount of a substance that can be dissolved by another substance
solubility
A measure of how much space an object takes up
volume
What is an upward push?
buoyancy
What is the center of an atom called?
nucleus
compound
The amount of matter in a certain volume of a substance
density
What are the three states of matter?
solid, liquid, gas
List the parts of an atom and their charges
proton= positive
neutron= neutral/no charge
electron= negative
A pure substance that cannot be broken down
element
An upward push of a liquid or gas on an object placed on it
buoyancy
What is the difference between physical and chemical properties?
physical can be observed/measured without changing the matter/object
chemical can be observed/measured but change the matter/object
describe the atoms in a solid, liquid, and gas
solid= close together, vibrate
liquid= spread apart a little, slide past each other
gas= move quickly all around, spread out
A particle that contains more than one atom joined together
molecule
what is matter?
anything that has mass and takes up space
What is the difference between mass and weight?
Mass is how much matter/how many particles are in an object
weight is gravity's affect on an object
weight changes mass does not
Describe the volume/shape of a solid, liquid, gas
solid= definite shape/volume
liquid= definite volume, no shape (of container)
gas= no definite shape/volume
