Each substance on the periodic table is called this
What is element
100
The microscopic parts of matter that have protons, neutrons, and electrons
What is atoms
100
This scale tells us whether a substance is acidic, basic, or neutral
What is pH
100
The type of change where no new substance is formed
What is physical change
200
The atoms of this type of matter are far apart and have lots of energy. It has no set volume or mass
What is gas
200
When two atoms join together to make a substance. H2O is a water example of this
What is molecule
200
The positively charged part of the atom in the middle
What is proton
200
An example of this is soda. It shows up red and low on the pH scale
What is acid
200
The type of change where a new substance is formed
What is chemical change
300
The atoms of this type of matter are close together. It holds its own volume and shape.
What is solid
300
A substance with two or more elements that are chemically bonded
What is compound.
300
The negatively charged part of the atom that swirls around in a cloud
What is electron
300
An example of this is baking soda. It shows up blue and is high on the pH scale
What is base
300
When you have a chemical reaction, the substances stay together because the atoms have a _____
What is bond
400
This state of matter has the atoms far apart, but flowing. It has a set volume but no set shape.
