Atoms
the 3 subatomic particles
what is a proton, neutron, and electron
This is how atoms create compounds.
what is share electrons?
These are vertical columns on a periodic table
What is a group?
The right side of the chemical equation is called this.
What is products?
When a substance changes into another substance with different properties
What is a chemical change?
the location of protons and neutrons
What is the nucleus?
This number tells you the number of protons
What is the atomic number?
These are horizontal on a periodic table
What is a period?
These are found on the left side of a chemical equation
What is the reactants?
This happens to reactivity of elements are you move down periods on the periodic table?
What is the reactivity of elements increases?
The atomic number is equal to these positive particles
What is a proton?
These determine how reactive an element is
What are valence electrons?
The atomic number tells us how many __________ an element has in its nucleus.
what is protons
C6H12O6 --> What is the 6 called?
What is a subscript?
This is a mixture that is uniform throughout.
What is a homogeneous mixture?
Which particle has the lightest mass
What is Electron
Name 1 element that acts similar to Ar
What is helium, neon, krypton, xenon or radon
This is how many electrons an atom wants to have and will combine with another element to make this number.
