Atomic Structure
This particle has a positive charge and lives in the nucleus.
What is a proton?
These are the vertical columns on the periodic table.
What are groups?
Ice melting into water is an example of this type of change.
What is a physical change?
This type of bond shares electrons between two nonmetals.
What is a covalent bond?
This is anything that has mass and takes up space.
What is matter?
These particles move in a cloud around the nucleus.
What are electrons?
These are the horizontal rows on the periodic table.
What are periods?
Burning wood is an example of this type of change.
What is a chemical change?
This type of bond happens when electrons are transferred between a metal and a nonmetal.
What is an ionic bond?
These are the 3 states of matter.
What is solid, liquid, gas?
This part of the atom doesn’t have a charge but adds to its mass.
What is a neutron?
This group of elements doesn’t like to react and is found in Group 18.
What are noble gases?
Rusting and burning are examples of this kind of property.
What is a chemical property?
This bond happens between metal atoms, where electrons move freely.
What is a metallic bond?
This is a substance made of only one kind of atom.
What is an element?
This number tells you how many protons are in an atom.
What is the atomic number?
These elements are shiny, conduct electricity, and are malleable.
What are metals?
This law says mass can’t be created or destroyed in a reaction.
What is the Law of Conservation of Mass?
These electrons are found on the outer shell and help atoms bond.
What are valence electrons?
This kind of mixture looks the same throughout, like saltwater.
What is a homogeneous mixture?
This is the distance from the nucleus to the outermost electron.
What is atomic radius?
These elements are in the middle of the table and have different charges.
What are transition metals?
Gas forming and color changing are clues that this has happened.
What is a chemical change?
These elements (like chlorine) are highly reactive and want to gain electrons.
What are halogens?
This property means an atom strongly attracts electrons in a bond.
What is electronegativity?
