Periodic Trends and Atomic Configurations
draw bohr model for potassium, include atomic and mass number
yeah I'll decide
why do elements bond?
to fill outside electron shell (octet rule)
weakest intermolecular force
london dispersion forces
Ammonium hydroxide mixed with iron (III) chloride produces ammonium chloride and iron (III) hydroxide.
3 1 3 1
what are intra vs intermolecular forces
intra is within the molecule, like bonds
inter is between different molecules
how many electrons can fit into each subshell
S P D F
2, 6, 10, 14
explain ionic, covalent and metallic bonds
ionic - metal and nonmetal, nonmetal steals electron
covalent - 2 nonmetals share electrons
metallic - sea of electrons, not enough EN to take
2nd weakest intermolecular force
dipole dipole forces
what is produced in combustion reactions
CO2 and H2O
is dissolving koolaid a physical or chemical change
physical
how does atomic radius and electronegativity affect ionization energy
more rings / space = electron shielding effect, less electronegativity = less hold on valence electrons
what are the naming rules for ionic and covalent compounds, try to name the most for points
covalent - use prefixes on both but no mono if the first one has only one, further left element usually goes first, drop a or o if needed (ex - pentoxide)
strongest intermolecular forces
hydrogen bonding
buzz words for synthesis and decomposition
and what are the special cases for decomposition
synthesis - burned with, combined
decomposition - decompose, strongly heated
special cases: carbonates split into CO2 and O, Hydroxides split into H2O and O, Chlorates split into Cl and O
name all the elements in whoofbrunkil
Hydrogen, Oxygen, Fluorine, Bromine, Iodine, Nitrogen, Chlorine
List out all the groups in the atom configuration in order ex: 1S ...
1S 2S 2P 3S 3P 4S 3D 4P 5S 3F 4D 5P 6S 4F 5D 6P
7S 6D 7P
how to determine polarity
find dipoles by cutting down middle and seeing if charge is evenly distributed
how are stains removed from clothing in the washing machine
detergent has both a polar and nonpolar side
Single replacement, double replacement buzzwords
and write equation: chlorine gas is bubbled through potassium bromide solution
single - bubbled through, placed in a solution
double - 2 solutions are mixed
calculate the AAM of an element with isotopes of 30, 31 and 32 with percentages of 20%, 30% and 50% respectively.
31.1 amu
Describe the 3 period trends we learnt about, include direction they go on the periodic table
Electronegativity (up right), atomic radius (down right), ionization energy (up right)
Draw the Lewis structure for NH3 and HCN
ill see
how does hydrogen bonding work
O, N and F can temporarily "bond" with a partially positive hydrogen atom if that hydrogen is also bonded with O, N or F
equation for methane (CH4) is burned
CH4+2O2→CO2+2H2O
find the energy of a wave with wavelength of 209 nanometers
5.93 x 10^3 joules
idk if this is right
