Chapter 12
The specific temperature where a solid transforms into a liquid.
What is melting point?
An atom has multiple orbitals. These type of electrons are on the highest orbital.
What are valence electrons?
A change of mixing substances makes a new substance.
What is a chemical change?
The number that represents the amount of protons in an atom.
What is the Atomic number?
A push or pull.
What is a force?
A force that pulls the molecules of a liquid together.
What is surface tension?
These show the ratio of elements in a compound.
What is a subscript?
The substances that go through a chemical change.
What are the reactants?
These are columns in the Periodic Table that represent the amount of valence electrons.
What are families? (groups)
This is a resistant force.
What is friction?
This type of solid has a repeating pattern.
What are crystalline solids?
A type of bonding where two atoms share electrons.
What are covalent bonds?
Matter is not created nor destroyed.
What is the Law of Conservation of Mass?
How would you find the amount of neutrons in an atom?
Subtract the Atomic mass by the amount of protons.
A force that pulls objects to each other.
What is Gravity?
Explain the difference between evaporation and boiling.
Evaporation is where the liquid on the surface turns into gas. Boiling happens at both the surface and the bottom.
