- The smallest particle of an element that keeps the element's properties
- atom
- the arrangement of electrons in an atom
- Electron Configuration
- electrons in the outermost layer of the orbitals
- valence electrons
- chemical symbol rep. nucleus and inner orbitals and surrounding dots represent valence electrons
- electron-dot structure
- The subatomic perticle's charges
- proton +1 Electron -1 Nuetron 0
- How are the subatomic perticles arranged?
- protons and nuetrons are contained in the nucleus and the electrons are in orbitals in the empty space around the nucleus
- there is a periodic repitition of chemical and physical properties of elements when they are arranged by increasing atomic number
- periodic law
- series of columns
- groups
- series of rows
- periods
- Groups designated with an A
- representative elements
- Groups designated with a B
- transition elements
- elements that are generally shiny when smooth and clean
- metals
- group of 1A metals except Hydrogen
- Alkali Metals
- Group 2A metals
- Alkaline Earth Metals
- Group B elements except lanthanide and actinide series
- transistion metals
- Group B elements that are lanthanide and actinide series
- inner transistion metals
- elements that are generally gasses or brittle
- nonmetals
- Group 7A elements, highly reactive
- halogens
- group 8A elements
- noble gases
- elements with physical and chemical characteristics of both metals and nonmetals
- matalloids
- Antoine Lavosiers creation in 1790's
- compiled a list of 23 elements
- John Newland in 1864
- organized a scheme for the first 23 elements
- 1869 Meyer & Mendeleev
- demonstrated a connection between atomic mass & properties & left blank spaces
- Mosely in 1913
- arranged the elements by atomic number
- How many rows does the periodic table have?
- 7 rows
- How many columns does the periodic table have?
- 18 columns
- The 5 things a box on periodic table can give us?
- 1) Name of the element 2) chemical symbol 3) atomic number 4) atomic mass 5) state of matter
- similiar in position, purpose or form
- corresponding
- important, of consequence
- significant
- passing from one place to another
- transit
- a solid figure generated by the revolution of a semicircle about it's diameter
- sphere
- Describe the relationship between the number of valence electrons and the chemical properties of an atom
- Elements with similiar chemical properties are in the same group w/ the same number of valence electrons
- table groups in block s
- 1A & 2A
- table groups in block p
- 3A to 8A
- table groups in block d
- 3B to 2B
- table groups in block f
- inner transistion metals
- atom or bonded group of atoms that has a positive or negative charge
- ion
- energy required to remove the first electron from an atom
- ionization energy
- atoms can share, gain or lose electron in order to get 8 electrons in outer orbital
- octet rule
- relative ability of it's atoms to attract electrons in a chemical bond
- electronegativity
- popular course, directions, or tendency
- trend
- How atomic size is defined
- how close it is to it's neighboring atom
- How atomic radii trend is
- decrease as you move left increase as you move down
- What happens when an atom loses and electron
- It becomes positive, it's size descreases
- What happens when you gain an electron
- the atom becomes negative the size increases
