| Positively charged subatomic particle that is found in the nucleus of an atom. | Proton
🗑
|
||||
| The neutral or no charge subatomic particle that is found in the nucleus of an atom. | Neutron
🗑
|
||||
| The negatively charged particle found in a cloud around the nucleus of an atom. | Electron
🗑
|

| The center of the atom, where the protons and neutrons are located. | Nucleus
🗑
|
||||
| Antother name for the location of electrons on the Bohr model: orbitals,energy levels, rings and ___? | shells
🗑
|
||||
| The name for the electrons found on the outermost shell or electron ring of an atom. | valence electrons
🗑
|
||||
| The name of the number on an element key that tells you the number of protons for that element. | atomic number
🗑
|
||||
| The name of the number on a periodic table element key that shows the number of protons plus neutrons. | atomic mass
🗑
|
||||
| This is used to describe atoms that have the same number of protons and electrons. | electrically neutral
🗑
|
||||
| Letters on the periodic table that are shorthand for the name | chemical symbol
🗑
|
||||
| Protons, neutrons and electrons; parts of an atom | subatomic particles
🗑
|
||||
| A pure substance, made only of one kind of atom | element
🗑
|
||||
| Model of an atom showing the placement and numbers of protons, neutrons and electrons | Bohr Model
🗑
|

🗑
|
||||
| Horizontal rows on the periodic table; elements in the same row have the same number of electron rings. | period
🗑
|
||||
| Elements arranged in columns; elements in the same column share similar chemical characteristics since they have the same number of valence electrons. | group
🗑
|
||||
| Elements found to the left of the zig-zag (metalloid) line; they have luster, are malleable, are good conductors and are solids. | metal
🗑
|

🗑
|
||||
| Group of elements that rest on the zig-zag line that show characteristics of both metals and nonmetals. | metalloids
🗑
|
||||
| Group number 18 on the Periodic Table which are inert due to the fact that their valence electron ring is full. | Noble Gases
🗑
|
||||
| Unreactive; will not react with other elements. | Inert
🗑
