Elements made by God are called what?
What is naturally occurring elements?
This is the charge of an electron.
What is negative?
When an atom's outer shell is not full of electrons, the atom is considered to be___________________.
What is unstable?
This unusual polymer wad discovered in 1940. It could be flattened, rolled, shaped, could bounce, and could pick up print from a newspaper.
What is Silly Putty?
This is a change where all the item's properties are essentially kept the same. (example: ripping pages in a book)
What is a physical change?
A group of one kind of atom is called this.
What is an element?
This is the charge of a neutron.
What is neutral?
The levels where the electron spends its time circling the atom are called the ________________ _________.
What are the electron shells?
This is the most common man-made polymer that is bad for the environment because it does not decompose.
What are plastics?
This is a change where the properties of a thing are changed. (Example: a burning log)
What is a chemical change?
This number represents the number of protons in an atom.
What is the atomic number?
This is the charge of a proton.
What is positive?
This is the number of electrons that can fit in the first electron shell.
What are two?
This is a solid with a regular, repeating arrangement of atoms.
What is a crystal?
These have a pH less than 7, taste sour or tart, feel watery, and ruins metals.
What are acids?
Elements are named by their Latin names. What is this called?
What is Binomial Nomenclature?
Atoms are made up of these three things.
What are protons, neutrons, and electrons?
This is the number of electrons that can fit in the second energy level of an atom.
What are eight (electrons)?
Name one kind of crystal commonly found in a home.
What are diamonds / salt / sugar / geodes?
These have a pH greater than 7, have a slippery feeling, are bitter tasting, and are great cleaners.
What are bases?
This is the number of protons and electrons an atom has.
What is the atomic mass or atomic mass number?
The nucleus of an atom contains these two things.
What are protons and neutrons?
These are electrons that exist in the outer shell of an atom.
What are valence electrons?
This is a molecule made of repeating small molecules combined. Examples are cellulose, natural rubber, plastics or nylon.
What is a polymer?
A chemical reaction during which heat energy is absorbed is called an ____________ ______________, and a chemical reaction during which heat energy is realeased is called an ______________ _____________.
What is an endothermic reaction?
What is an exothermic reaction?
