What is electronegativity?
Electronegativity is the ability of the atom to attract electrons when the atom is in a compound
100
What are valence electrons?
Valence electrons are outermost electrons or electrons in the highest energy sublevel

Explain general electronegativity trends

In general, electronegativity values decrease from top to bottom within a group. For representative elements, the values tend to increase from left to right across a period.

The atom with the highest electronegativity value, Flourine, has how many valence electrons in its highest energy level?
7
200
What is the electron configuration for Helium?
What is 1s2
300

Which atom has a bigger atomic radius Chlorine or Calcium?

Why? Relate this to shielding

Calcium

It has more energy levels. (4 shells)

300

Which element has a higher ionization energy Mercury or Polonium?

Why?

Polonium

Higher nuclear charge (protons pull in valence electrons more)

300

Rank these 5 elements from least to greated electronegativity Al, Mg, Si, S, Cl

What is 

Mg, Al, Si, S, Cl

Describe the shielding effect on an atom.

When an atom has more energy levels (shells) it blocks the attraction between the protons and valence electrons.

400

Which of the following four elements has the lowest electronegativity why?: Li, Na, K, Rb, Cs

What is Cs or Cesium.

It is the most shielded out of all of these. Most energy levels

400
Rank the following atoms in most to least shielded: Oxygen, Calcium, Phosphorus, Helium

Ca --> P --> O --> He

What is the electron configuration for Selenium
What is 1s2,2s2,2p6,3s2,3p6,4s2, 3d10,4p4
500

What increases from left to right in a period?

(Hint: Related to shielding)

Positive charge of nucleus

500
Why does ionization energy increase from left to right across a period?
Because nuclear charge increases but the shielding effect stays the same
500
What is he difference between electronegativity and ionization energy?
Ionization energy is the energy needed to remove an electron and electronegativity is the tendency to attract electrons when the atom is in a compound
