Write down the 3 divisions and numbers that you must use after you subtract the

Electronegativity numbers between 2 atoms in a

molecule.

$200Properties of the elements that repeat

consistently across the periods, determined by electron configuration

What is the definition of Periodic Properties?

$400

Amount of pull the valence electrons feel from protons in the nucleus

What is the effective Nuclear Charge (Z)?

$600

Stays the same

The effective nuclear charge trend for going down a

family…

$800

Goes up, because protons increase while shielding electrons stays the same

Going across a period, the effective nuclear charge...

$1000

Atomic size

What is the size of an atom called?

$200

Effective nuclear charge and energy levels

What are factors which affect the size of an atom and how they affect it ?

$400

Increases due to the adding of more energy levels

Trend of atomic size going down a family…

$600

Trend of atomic size going across a period

What Decreases due to energy level staying the same, while effective

nuclear charge increases (more pull on valence electrons)?

$800

What is the energy needed to move an electron?

Ionization Energy

$1000

The effective nuclear charge and atom size

What are factors which affect ionization energy and how they affect it ?

$200

Trend of ionization energy going down a family

What decreases (easier to remove) because size is

bigger, so valence electrons are further away ?

$400

Trend of ionization energy going across a period

What increases (harder to remove) due to effective nuclear charge

increasing (more pull - more likely to attract electrons) ?

$600

Electronegativity

What energy is needed to add an electron (likeliness to

gain)?

$800

effective nuclear charge and atom size

What factors which affect electronegativity and how

they affect it ?

$1000

Decreases.. if size is bigger, less pull from nucleus

•What is the trend of electronegativity going down

a family

$200

Increases due to effective nuclear charge being greater

Trend of electronegativity going across a period

$400

Ionic Size

Size of an ion

$600

to organize elements in meaningful way

Why was periodic table developed?

$800

Mendeleev - increasing molar mass, while today’s is increasing atomic number

How was Medeleevs scheme for listing elements different from that used in the modern

periodic table?

$1000

elements in same group have same number of valence electrons

What relationship can be seen between an elements

placement within a group and its electron configuration?

$200

Noble gases had not been discovered yet due to their inactivity

Why did Group 8 not appear on the Mendeleev periodic

table?

$400

increasing tendency to form neg ions therefore use less energy (minus -:

Exothermic

Trend of electron affinity across left to right

$600farther from nucleus therefore uses less

energy to add an electron also shielding can add electrons

Trend of electron affinity down top to bottom

$800

X + e− → X−

Equation electron affinity

$1000

M(g) + hn ® M+ + e-.

Equation for ionization energy

$200

both negative ions (right side) give off energy to gain an electron + ions use

energyElectron affinity energy can

be what: + or -?

$400

1) shielding 2) Effective (Strong) nuclear charge 3) add another orbit of electrons

increases distance from nucleus

Name 3 concepts that can affect periodicity

$600Protons and neutrons in element 114

What exactly do these two pictures represent and where

are the from?

$800

The equal the levels from the nucleus out.

How do the periods on the periodic table relate to the electron orbitals and the

nucleus.

$1000

1s2 2s2 2p6 3s2 3p2 and [Ne] 3s2 3p2

Long and short electron configuration for silicon.

Daily Double

Dalton, Thompson, Rutherford and Bohr…Schrödinger, and Heisenberg
