With the symbol (O), it makes up about 21% of the earth's atmosphere.
OXYGEN
This type of bond forms when electrons are transferred from one atom to another.
IONIC BOND
An insoluble solid that emerges from a liquid solution.
PRECIPITATE
This state of matter has a definite volume but takes the shape of its container.
LIQUID
The region around a magnet is where magnetic forces can be detected.
MAGNETIC FIELD
The lightest element on the periodic table and has the atomic number 1.
HYDROGEN
This type of bond forms when two atoms share electrons.
COVALENT BOND
In the Law of Conservation of Mass, this quantity remains the same before and after a chemical reaction.
MASS
In this state of matter, particles move freely and spread out to fill the entire container.
GAS
The two ends of a magnet where the magnetic force is strongest.
NORTH & SOUTH
This element has the atomic number 79, does not corrode and has been used in jewelry and currency.
GOLD
Metals bonded together in a "sea of electrons" form this type of bond.
METALLIC BOND
This reaction happens when two or more substances combine to form a single product.
SYNTHESIS or COMBINATION REACTION
This state of matter has a definite shape and a definite volume because its particles are tightly packed.
SOLID
This LAW states that opposite magnetic poles attract while like poles repel.
LAW OF MAGNETIC ATTRACTION AND REPULSION
With the symbol (Fe) this element is essential for carrying oxygen in human blood.
IRON
These are electrons with the highest energy level and held most loosely on the outside energy level.
VALENCE ELECTRONS
This type of this reaction is where one compound breaks apart into TWO OR MORE simpler substances.
DECOMPOSITION REACTION
This state of matter is made of ionized particles and is commonly found in stars and lightning.
clue: once popular in large screened TVs
PLASMA
Increasing the number of wire coils or the ELECTRIC current will increase the strength of this device.
ELECTROMAGNET
Which Russian chemist is known as "the father of the periodic table"?
Dmitri Mendeleev
Sodium (Na) loses one electron and Chlorine (Cl) gains one electron to form this compound.
SODIUM CHLORIDE
These are numbers placed in front of chemical formulas to balance an equation.
COEFFICIENTS
According to the particle model of matter, increasing temperature causes particles to do this.
SPEED UP (gain kinetic energy)
The invisible force that causes a compass needle to point NORTH.
