Matter
Anything (or stuff) that has mass and takes up space.
Matter
This particle carries a positive charge.
Proton
Can an atom stand alone?
Yes. An atom is the smallest particle of an element that can exist alone.
This organizes information about the elements and their properties
The Periodic Table
A pure substance that contains one type of atom
Element
All matter is made up of these things that act as tiny particles.
Atoms
This particle carries a neutral charge.
Neutron
The abbreviation of an element is called a
Symbol
The horizontal rows on the periodic table are called
Periods
A pure substance that contains two or more types of atoms
Compound
List the four states of matter.
Solid, liquid, gas, and plasma
This particle carries a negative charge.
Electron
The Atomic mass is equal to the number of
protons and neutrons
The vertical columns are known as
Groups
List the two types of mixtures.
This theory states that the tiny particles in all forms of matter are in constant motion.
Kinetic Theory
These two particles make up the nucleus.
Protons and neutrons
The Atomic Number is equal to the number of
Protons and electrons
If the element's symbol is represented with one letter then the first letter of the symbol should be
Capitalized
When does a solution form?
When one substance is dissolved by another.
What is the basis of classification of the four types of matter?
Based upon particle arrangement. Based upon energy of particles. Based upon distance between particles
This particle circles the nucleus.
Electron
What happens when an atom gains electrons?
It becomes negative.
Describe how the element's symbol should be represented if the symbol has two letters.
If the element's symbol is represented with two letters then the first letter of the symbol should be capitalized and the second letter should be lowercase.
How can a compound be separated?
