Atomic Radius
Distance
Which subatomic particle is ionization energy removing from an atom?
Electron
Electronegativity deals with the ability of an atom to ___________ electrons
gain
Rows on the periodic table are called
Periods
How many electrons can each orbital hold?
2
Which element has the larger atomic radius: Oxygen or Sulfur?
Which element has the lower IE: Silicon or Sulfur?
Silicon
Which element has the highest EN?
Fluorine
What word means ability to bend?
Malleable
How many electrons can the 2nd energy level hold?
8
What is the Shielding Effect?
The inner electrons “shield” or block the attraction from the nucleus.
What is the nuclear charge?
The attraction between the protons and electrons
Which element has a higher electronegativity? Chromium or Zinc
Zinc
Elements in the same _________ (group or period) have similar properties
Group
Which element has the following Noble Gas abbreviation:
[Kr] 5s2 4d10 5p4
Tellurium
Why is there more distance between electrons and protons as you go down a group?
More energy levels (rings) are added as you go down
Why does the IE increase as you go across a period?
More protons means increased nuclear charge
Why are Noble Gases not included in EN?
They are already full of valence electrons and can't accept any more (reactivity)
Metals
