Name 6 Metalloids & how to find them on PT
B Si Ge As Sb Te They're that weird diagonal looking thing
Terms for rows & columns on PT
Rows = periods Groups = columns
what does mass spectrometry measure, & through what
% comp of mass in a sample, through mass spectra (wacked-out-looking bar graphs)
what’s the octet rule
“many neutral atoms want to either lose/gain e- to get the same # of total e- as the closest noble gas”
what 2 groups form ions
metals & nonmetals
define ion
atoms/groups of atoms with an overall charge
3 fixed-charge ions to memorize
Zn⁺²
Ag⁺
Cd⁺²
def fixed-charge ion
elements that can make only 1 type of ion
def variable charged ion
a metal that isn’t fixed charge
def atom # x 5
ID on PT #p+ whole # #e- in neutral state on bottom of complete symbol
def mass # x 4
p+ + n
whole #
not on PT
on top of complete symbol
4 parts of complete symbol, & what it’s called w/
mass # charge
Symbol
atom #
“element-mass #” or “element mass #”
Define isotope
same element, diff # of n
def atomic mass x 2
- NOT on PT
- mass of a single isotope
def avg atomic mass x 2
- on PT
- avg of all natural isotope masses
def amu x 3
- atom mass unit
- 1/12 of carbon-12
- exact; estimate to 1’s place
