This is a substance made up of only one kind of atom.
What is an element?
100
I am a particle of matter with a positive electric charge, what am I?
What is a proton?
100
This is the way elements are organized.
What is the Periodic Table of Elements?
100
This is the organization of electrons around the nucleus of an atom.
What is electron configuration?
100
When atoms share electrons or "hold hands" -- this type of bonding occurs.
What is covalent bonding?
200
This is a substance made of two or more different elements bound together in a constant ratio.
What are compounds?
200
I am a particle of matter that carries no charge, or is neutral. What am I?
What is a neutron?
200
This the letter or abbreviation for the element in the periodic table.
What is the element name or symbol?
200
This is the diagramming model to portray electrons moving around the nucleus. It was named for a Danish Physicist.
What is the Bohr Model?
200
This type of bonding occurs when atoms donate electrons or give them up.
What is ionic bonding?
300
I like to be solid sometimes, maybe liquid, often gas, but plasma is the coolest.
What are the four forms of matter?
300
I am the smallest particle of matter, I have a negative charge and orbit around the nucleus -- what am I?
What is an electron?
300
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.
What is the atomic mass?
300
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?
What are two and eight?
300
When molecules are the made of the same kind or identical atoms, they are called what?
What are homonuclear diatomic molecules?
400
I am made up of only one kind of atom, what am I called?
What is an element?
400
Positively charged ions are called this.
What are cations?
400
The slight variation of neutrons in any element is called this.
What is an isotope?
400
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?
What is up to 18 electrons?
400
This is known as the combined mass of the atoms and is obtained by adding up the amu of each atom in a molecule.
What is molecular mass?
500
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.
What is compound vs. mixture?
500
Negatively charged ions are called this.
What are anions?
500
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.
What is the atomic number?
500
What are the electrons that are contained in the outermost orbital called?
What are valence electrons?
500
I am a fancy scientific conversion unit of atoms to grams. But you can just call me 6.022 x 10 to the 23rd.
