What do you call elements that are within the same column on the periodic table?
Elements that are within the same column on the periodic table are called groups.
100
What does atomic theory state?
Atomic theory states that all matter is composed of atoms.
100
What are the three main states of matter?
The three main states of matter are solid, liquid, and gas.
200
Where are the metals located on the periodic table? List 3 common properties that metals share.
On the periodic table, the metals are located to the left of the zig zag line. Three common properties that metals share include luster (shiny appearance), malleability (easily shaped), and high conductivity of heat and electricity.

Describe the structure of an atom.
An atom is composed of a tiny, massive nucleus containing positively charged protons and neutral neutrons. Traveling around the nucleus are one or more negatively charged electrons.
200
What is the Kinetic Theory of Matter?
The Kinetic Theory of Matter is the idea that in all substances, molecules and the atoms that make them up are in constant motion.
300
On which side of the periodic table are the nonmetals located?
On the periodic table, the nonmetals are located to the right of the zig zag line.
300
What is the difference between an element and a compound?
The difference between an element and a compound is that elements are pure substances made up of only one type of atom, whereas compounds are made when two or more elements combine.
300
What does the movement of molecules, or state that matter is in, depend on?
The movement of molecules depends on its temperature.
400
List 2 common properties that nonmetals share.
Two common properties that nonmetals share are that they are brittle and poor conductors of heat and electricity.
400
What is the difference between a covalent bond and an ionic bond?
The difference between a covalent bond and an ionic bond is that in a covalent bond, a pair of electrons is shared between two atoms and in an ionic bond, electrons move from one atom to another.
400
What is the difference between matter that is in a solid state and matter that is in a gas state?
Matter that is in a solid state has a definite shape and volume, whereas matter that is in a gas state has no definite shape or volume.
500
Where are the semimetals (metalloids) located on the periodic table? What are some properties that semimetals share?
Semimetals are located along the zig zag line on the periodic table. Some common properties that nonmetals share are that they are brittle (like nonmetals), but good conductors of heat and electricity (like metals).
500
What happens to the physical and chemical properties of separate elements when they combine with each other?
When separate elements combine with each other the chemical and physical properties of the new compound are different from those of the atoms that make up that compound.
500
What is the difference between the melting point and freezing point of a substance?
The melting point is the point at which a solid changes to liquid, whereas the freezing point is the point at which a liquid changes to a solid.
