|---|---|---|---|---|---|
| Atomic Number | The number of protons in the nucleus. Protons = Electrons
🗑
|
||||
| Electron | Negatively charged subatomic particle. Found outside of the nucleus. 1/2000 the mass of a proton or neutron.
🗑
|
||||
| Proton | Positively charged subatomic particle found in the nucleus.
🗑
|
||||
| Neutron | Subatomic particle with no charge found in the nucleus
🗑
|
||||
| Period | Horizontal row of the elements. It also stands for the number of electron shells around the element. Example Carbon is in period 2 so it has 2 electron shells.
🗑
|
||||
| Group/Family | Vertical column of elements with similar but not identical properties. Same number of valence electrons.
🗑
|
||||
| Valence Electrons | Electrons in the outer shell. This is where covalent bonds are formed between non-metals.
🗑
|
||||
| Atomic mass | Average mass of protons and neutrons in the nucleus. To find the average number of neutrons in an element subtract the atomic number from the atomic mass.
🗑
|
||||
| Atomic Mass Unit (AMU) | Unit used to measure subatomic particles. Protons and neutrons have a mass of 1 amu.
🗑
|
||||
| Alkali Metals | This family has 1 valence electron.
🗑
|
||||
| Mercury | This element is liquid at room temperature and found in the transition metals.
🗑
|
||||
| Nitrogen | This family has 5 valence electrons
🗑
|
||||
| Halogen | This family is made up of extremely reactive non metals.
🗑
|
||||
| Thorium | This element has 90 electrons.
🗑
|
||||
| Noble Gases | This family is unreactive and inert.
🗑
|
||||
| Boron | This family has 3 valence electrons.
🗑
|
||||
| Transition Metals | This family's electrons can jump between electron shells and usually has 1 or 2 valence electrons.
🗑
|
||||
| Subscript | Number in the lower right hand corner that represents the number of atoms of an element in a compound.
🗑
|
||||
| Carbon | This family has 4 valence electrons
🗑
|
||||
| Krypton | This element has 8 valence electrons
🗑
|
||||
| Strontium | This element has 5 electron shells.
🗑
|
||||
| Selenium | This element has 45 neutrons.
🗑
|
||||
| Molecule | combination of two or more atoms.
🗑
|
||||
| Chemical Symbol | Shorthand way to represent an element
🗑
|
||||
| Subatomic Particles | Proton, neutron, and electron
🗑
|
||||
| Metals | These are on the left side of the zigzag on the periodic table
🗑
|
||||
| Non-metals | These are on the right side of the zigzag on the periodic table
🗑
|
||||
| Magnesium | This element has an atomic number of 12
🗑
|
||||
| Copper | This element has an atomic mass of 64.
🗑
|
||||
| Gold | Symbol Au stands for what element?
🗑
|
||||
| Energy Level | Location of electrons in the electron cloud.
🗑
|
||||
| Compound | Anything made up of two or more elements (must be different elements).
🗑
|
||||
| Octet Rule | Rule of thumb that elements tend to bond so each atom has 8 valence electrons in their outer shell.
🗑
|
||||
| Coefficient | Number placed in front of the symbol or a formula in a chemical equation that indicates how many atoms or molecules of this substance are involved in the reaction.
🗑
|
||||
| Alkaline Metals | This family loses both of its valence electrons when it bonds.
🗑
|
||||
| Oxygen | This element has 6 valence electrons.
🗑
|
||||
| Mass Number | The sum of protons and neutrons in the nucleus. This is the exact number for as isotope.
🗑
|
||||
| Black | Color used to represent a carbon atom in a molecule.
🗑
|
||||
| Red | Color used to represent an oxygen atom in a molecule.
🗑
|
||||
| Blue | Color used to represent a nitrogen atom in a molecule.
🗑
|
||||
| White | Color used to represent a hydrogen atom in a molecule.
🗑
|
||||
| Coefficient | Number that is placed in front of a symbol or a formula that indicates how many atoms or molecules of this substance are involved in the reaction.
🗑
|
||||
| Sodium | This element is in period 3.
🗑
|
||||
| Mass Number | Sum of the protons and neutrons in the nucleus of an atom.

🗑
|
||||
