8- reactivity trends Flashcards
An atoms ability to accept electrons
Electron affinity
ability of an atom to attract and bind electrons
electronegativity
shows how reactive metals are to chemical 1 changes
metallic property
it is used to identify the size of an atom based on how far the nuclei are
Atomic radius
The founder of the periodic table
Dmitri Mendeleev
what is the periodic table
it is a chart/ table that is arranged based on the number of the protons and grouped based on its similar characteristics
how many elements in the periodic table
118
what are the trends in the periodic table?
Electronegativity, Atomic Radius, Metallic property, Ionization energy
why are noble gasses so inert?
They have stable electron configuration
Electron negativity:
1. Down
2. Up
3. Left
4. right
- Low %
- High %
- Low
- High
the energy required to remove an electron from a neutral atom in its gaseous state
Ionization energy
Atomic radius: High
Down, lefy
Low Ionization energy =
easy to remove an electron
High Ionization energy =
hard to remove electron
refers to the arrangement of electrons in an atom or ion.
electron configuration
why is it on the left side of the periodic table atoms give electrons easily?
to achieve stable electron configuration
the tendency of an element to be shiny, silver, malleable, ductile and to react to from positive ions
metallic character
it is the energy released when the electron is added to the attom
electron affinity
electron affinity: High
Up: right
