  Answer: This trend describes the distance from the center of the nucleus to the outermost shell of an atom.

Atomic radius

100

In the formula Zeff =Z−S, this letter represents the total number of protons in the nucleus (the Atomic Number).

Z

100

This type of bond involves the transfer of electrons between a metal and a non-metal.

ionic bond

100

When a metal loses an electron, it becomes this type of positively charged ion.

Cation

100

This property means a metal can be drawn out into thin wires.

Ductile

200

As you move from left to right across the periodic table, this energy "cost" to remove an electron increases.

Ionization energy

200

This letter represents the "Shielding" or "Screening" constant, which is the number of inner-shell electrons

S

200

In this type of bond, electrons are shared between two non-metals.

Covelant bond

200

When a non-metal gains an electron, it becomes this type of negatively charged ion.

Anion

200

This property describes a metal's ability to be easily bendable or hammered into sheets.

Malleable

300

This term represents the actual "net" positive charge that a valence electron feels from the nucleus after shielding is taken into account.

effective nuclear charge (Zeff)

300

If the difference in this value (ΔE1) is greater than 1.7, the bond is considered Ionic.

electronegativity

300

This term describes a group of different atoms and ions, like S2− and Ar, that all have the same number of electrons.

isoelectronic Series

300

This is the scientific term used to describe a metal as being "shiny."

Luster

400

What is Horizontal Trend (or Right-to-Left)?

Atomic radius

400

When calculating S for the formula, you only count these types of electrons, not the ones in the outermost shell.

core electrons

400

This bonding type is described as a "sea of electrons" surrounding protons and neutrons.

Metalic bonding

400

 According to your notes, this is the most electronegative element on the periodic table.

F

400

This is the energy required to pull an ionic compound apart into its gaseous ions.

lattice energy

500

Bigger the differance in the electronegativity between 2 elements the more 

polar the bond is until it reaches 1.7 then it becomes an ionic bond

500

 Zeff  represents this type of relationship between the nucleus and the valence electrons.

Atraction

500

Ionic substances bond together in this specific pattern, which makes them brittle and gives them high boiling points.

Lattice form

500

Your notes highlight that this specific element "wants all electrons" and is highly reactive.


Cl chlorine

500

These are the two factors that determine the strength of an ionic bond.
