Atomic radius trends

decreases to the right, Increases down

Ionization energy trends

Increases to the right, decreases down

Electronegativity trends

Increases to the right, decreases down

Ionic radius trends

Cations are smaller than neutral atoms, while Anions are bigger than neutral atoms

Valence electrons on periodic table

Groups 1-2 and 13-18. Increases from 1 to 8

Ionic charges on periodic table

Groups 1-2 and 13-18. Goes from +1, +2, +3, 0, -3, -2, -1, 0

Metals definition and location

Conducts heat and electricity. Mainly on the left and center

Nonmetals definition and location

Lacks Metal traits. Mainly on the right side

metalloids definition and location

Shares properties with metals and nonmetals. Found on the stair step line, starting at group 13, 1 2 2 2 1 on right

Periodic law

When elements are listed with increasing atomic number, their properties repeat

isoelectronic

same number of electrons

Calcium ion

Ca +2

A positive, negative and neutral ionic charge is most likely to

positive: lose electrons, Negative: gain electrons, Neutral: Neither Gain or lose electrons

How to determine reactivity

The more down and left you are.

How adding electrons work

Do the opposite that the sign says.

metals or nonmetals will form cations or Anions

Metals form cations, nonmetals form Anions

How is the periodic table arranged?

By increasing atomic number

Elements with the highest and lowest electronegativity

The highest is Flourine, the lowest is Francium

Elements with the highest and lowest atomic radius

The highest is Francium, the lowest is Helium

Elements with the highest and lowest ionization energy

The highest is Helium, the lowest is Francium

elements with zero electronegativity

Noble gases
