the basic unit of matter. Smallest unit of a chemical element. Each of these contains a nucleus (the center)
What is an atom
100
Three principle subatomic particles
What are protons, neutrons, & electrons
100
is anything that has mass and occupies space. The amount in an object is mass. Occurs as either a pure substance or a mixture.
What is matter
100
is either an element or a compound with one constant composition.
What is PURE SUBSTANCE
100
is the simplest and least complex form of matter. Cannot be broken down into simpler substance by normal chemical means
What is an ELEMENT
200
composed of two or more elements.
What is a Compound?
200
a combination of atoms joined as a single particle.
What is a molecule
200
Classify:
Color
Physical property or state
Solid
Liquid
Gas
What are PHYSICAL PROPERTIES OF MATTER
200
an atom with an electrical charge due to having either more or fewer electrons than protons
What is an Ion
200
an atom that has more protons than electrons (positive charge).o
What is Cation
300
is the attraction between positively charged ions and negatively charged ions.
What is Ionic bonding
300
Any substance that reacts in water to yield the hydrogen Cation, H+
Some examples are:
Hydrofluoric acid (HF)
Hydrochloric acid (HCl)
Sulfuric acid (H2SO4)
What is Acid
300
Any substance that produces the hydroxide anion (OH-) in water. When dissolved in water, these compounds detach into ions
What is Base
300
The reaction of an acid and a base union. Reaction yields water and a saltons.
What is Neutralization reaction
300
Since, they do not consist of ions. The atoms in a covalent compound form into small groups called molecules.
What is COVALENT BONDING
400
made by the donation of excess electrons.
What is METALLIC BONDING
400
any substance that reacts in water to yield the hydrogen cation, H+
What is ACID
400
any substance that produces the hydroxide anion (OH-) in water.Š
What is BASE
400
The reaction of an acid and a base;yields water and salt.
What is NEUTRALIZATION REACTION
400
a solution that resists changes in ph.T
What is BUFFER
500
the science of extracting metals from their ore, purifying them, and preparing them for practical use.ecules.
What is METALLURGY
500
a mixture of two or more elements that has the properties of a metal"
