The Nucleus is made up of what two components and account for the mass of an atom?
Protons and Neutrons
The Atomic # is equal to the number of what ?
Protons
The Atomic Mass is equal to the mass of what 2 Atomic particles ?
Protons and Neutrons
This occupies space and has mass ?
Matter
Because the periodic chart lists atoms in a "Neutral" state, the number of protons (positive charge) has to be equal to what ?
The number of Electrons
What are the positively charged sub-atomic particles found in the nucleus ?
Protons
The space surrounding the nucleus of an atom contains ......
Electrons
This is the type of ion that forms when an atom loses electrons.
Positive
This is the electric charge of an Electron.
Negative
This is a substance that is composed of only one type of atom.
Element
This is a type of bond where the electrons are "transferred".
Ionic
This is the place in the atom where the Neutrons are found.
Nucleus
This is the type of bond where the Electrons are "Shared".
Covalent
This has definite shape and definite volume.
Solid
This does not have definite shape or definate volume.
Gas
This has definite volume but no definite shape.
Liquid
The three states of matter are ....
Solid, Liquid and Gas
This changes due to gravity.
Weight
This does not change due to gravity.
Mass
The nucleus is found where in the atom ?
Center
When is an atom most stable ?
When it has a full "outer shell" or "Orbital" ( Look for any of the nobel gases, which have 8 )
How many valence electrons go on the 1st shell ?
Up to 2 electrons
How many valence electrons go on the 2nd shell ?
Up to 8, must fill up first shell before putting any electrons onto the 2nd shell.
How many valence electrons go on the 3rd shell ?
Up to 8, must fill up first and second shell before putting any electrons onto the 3rd shell.
The name of the electrons found on the outer shell ( orbital ) of an atom.
Valence Electrons
How do you figure out how many Neutrons are in an atom ?
Atomic Mass - Atomic # ( Protons ) = Neutrons
What kind of charge do Neutrons have ?
Neutral charge
Two of the same atoms that differ only in the number of neutrons are called .....
Isotopes
