Atomic mass
Total amount of protons + neutrons
19
New cards
How to find # of neutrons
Atomic mass (round to nearest whole number) - Atomic number
20
New cards
Isotopes
\-Atoms of the same element with different amounts of neutrons
21
New cards
Energy level
Region of space that may have electrons
22
New cards
Valence electron
Outermost shell/level of an element
23
New cards
Electron shell/level amount of attraction
\-Electron shell/level closest to the nuclues has strongest attraction
\-Electron shell/level farthest from nucleus has weakest attraction
\-Electron shell/level farthest from nucleus has weakest attraction
24
New cards
Atom vs Ions
Atom: Neutral charge (Amount of protons=Amount of electrons)
Ion: Positive or negative charge (Amount of extra electrons added/taken away to make complete valence shell)
Ion: Positive or negative charge (Amount of extra electrons added/taken away to make complete valence shell)
25
New cards
Ionization
Process of gaining/losing electrons to complete valence shell
26
New cards
Cations
\-Losing electrons
\-Leaves positive charge
\-Leaves positive charge
27
New cards
Anions
\-Gaining electrons
\-Leaves negative charge
\-Leaves negative charge
28
New cards
Octet rule
energy level sequence: 2,8,8,1
\-Most atoms don’t want neutral charge (e- = p+)
\-Atoms want to complete their valence shell
\-Most atoms don’t want neutral charge (e- = p+)
\-Atoms want to complete their valence shell
