Electronegativity
Which element is more electronegative O, or F
F as it has a smaller atomic radius and more positive nucleus
What has a higher Ionization energy between H and He
He
Nitrogen
Hydrogen.
The Rows to the Periodic Table of Elements are called what?
Atomic periods
Which element is less electronegative C or Si
Si because it resides in the 3rd period and has a higher principal energy level.
What has a higher Ionization Energy, Li or Ne
Ne
What Ion with a +1 charge has the electron configuration 1s22s22p6
Sodium, Na
Arrange the elements from smallest to largest. F, As, S
What group hakes up the 17th Column of the Periodic Table
The Halogens
Which element is more electronegative Zn or Sc
Zn as it has a smaller atomic radius
N as it has a smaller radius and is more electronegative.
What neutral atom has a electron configuration 1s22s22p63s13p1
Mg, Magnesium
Columb's describes the relationship between the force on an atoms valence electrons as being ______ proportional to atomic radius
Inversely
How many Periods are there in the Periodic Table of Elements
7
Which element is more electronegative, Cl or Ar?
Cl as Ar has a smaller radius but filled valence electron shell
What element has a higher Ionization Energy, Sr or Ca
Ca as it has a smaller atomic radius.
What -2 charged ion has the electron structure 1s22s22p6
Oxygen
What has a smaller atomic radius H or He
He
What are the names of the two periods that are included at the bottom of the Periodic Table of Elements
The Lanthonides and Actinides
What is the most electronegative element
Florine
Based on our trends, which element has the lowest possible Ionization Energy
Fr
Why does the first D-block start in the 4th period but have an electron structure 3d
Because of its proximity to the nucleus and hybridization with the third principal energy level
Arrange the elements from smallest to largest, Sc, Ga, P
Why do both the first two groups contain the word Alkali?
Because these atoms are Basic rather than acidic.
