Chemistry Ionic Bonds

An Ion is

an atom with a positive or negative charge

A Cation is

A positive ion

An anion is

a negative ion

electronegativity is

how much an atom wants an electron

The most electronegative atom is

Flourine

When an atom is closer to fluorine it becomes

more electronegative

Why do atoms want 8 valance electrons

to become stable/unreactive

Ionic bonds are between a

metal and non-metal

All salts are

ionically bonded, dissolve in water, conduct electricity, solid at room temp, brittle

Lewis dots show

valence electrons

When naming an ionic bond you use

‘metal name’ ‘non-metal -ide’

If an atom loses electrons, it’s ion is

positive

if an atom gains electrons, its ion is

negative

When naming an ionic bond with transition metals you use

‘metal name’ ‘roman numeral for charge’ ‘non-metal -ide’

When a compound uses more than 1 of a specific poly atomic ion, you write it as

‘ (poly atomic ion) -subscript, number of-’

When we did the mega blocks experiment, did the cation or anion go on top

cation

What charge should a compound formula have

neutral

Ionization energy is

the amount of energy needed to remove an electron

The ionization energy trend goes

left and up

higher ionization energy means

an atom is less likely to loss an electron

higher elctronegativity means

an atom is more likely to attract an electron

are noble gases electronegative

no

do noble gases have a high ionization energy

yes

what is an atoms goal

to have a full outer shell

do you do top or bottom first in electron configuration

bottom

how many electrons can go in each orbital

2

what is the shape of the S sub-shell orbitals

sphere

what is the shape of the P sub shell orbitals

dumbbells (3)

what is the shape of the D sub shell orbital

4 leaf clover

what is the shape of the F sub shell orbitals

Tetrahedral

Max number of electrons in a S sub shell

2

max number of electrons in a P sub shell

6

max number of electrons in a D sub shell

10

max number of electrons on a F sub shell

which part of a compound determines the color of it’s flame

the metal
