This is a substance made up of only one kind of atom.

What is a proton?
I am a particle of matter with a positive electric charge, what am I?
100
What is the Periodic Table of Elements?
This is the way elements are organized.
100
What is electron configuration?
This is the organization of electrons around the nucleus of an atom.
100
What is covalent bonding?
When atoms share electrons or "hold hands" -- this type of bonding occurs.
200
What are compounds?
This is a substance made of two or more different elements bound together in a constant ratio.
200
What is a neutron?
I am a particle of matter that carries no charge, or is neutral. What am I?
200
What is the element name or symbol?
This the letter or abbreviation for the element in the periodic table.
200
What is the Bohr Model?
This is the diagramming model to portray electrons moving around the nucleus. It was named for a Danish Physicist.
200
What is ionic bonding?
This type of bonding occurs when atoms donate electrons or give them up.
300
What are the four forms of matter?
I like to be solid sometimes, maybe liquid, often gas, but plasma is the coolest.
300
What is an electron?
I am the smallest particle of matter, I have a negative charge and orbit around the nucleus -- what am I?
300
What is the atomic mass?
This is the number that represents the number of protons and neutrons in an atom of the element. This appears either above element name or the upper right on the periodic table of elements.
300
What are two and eight?
When I am in the first orbital, I can hold this many electrons, but get me to the second orbital and I can hold this many electrons?
300
What are homonuclear diatomic molecules?
When molecules are the made of the same kind or identical atoms, they are called what?
400
What is an atom?
Most of what we know as matter is made up of tiny particles called these?
400
What are cations?
Positively charged ions are called this.
400
What is an isotope?
The slight variation of neutrons in any element is called this.
400
What is up to 18 electrons?
Being in the third orbital is really great -- it's like a party of electrons. Well, actually only a party that can hold how many people?
400
What is molecular mass?
This is known as the combined mass of the atoms and is obtained by adding up the amu of each atom in a molecule.
500
What is compound vs. mixture?
When I am in this form, I am made up of two or more elements bound together. But when I am in this other form, I am not bound together.
500
What are anions?
Negatively charged ions are called this.
500
What is the atomic number?
This is the whole number that represents the number of protons in an atom of an element. It appears on the upper left in the periodic table.
500
What are valence electrons?
What are the electrons that are contained in the outermost orbital called?
500
What is a mole?
I am a fancy scientific conversion unit of atoms to grams. But you can just call me 6.022 x 10 to the 23rd.
