when Na loses an electron->?
hint: name the element along with it's charge.
Sodium Na1+
This man contributed the uncertainty principle which stated that we can not know the exact position or trajectory of an electron
Who is Heisenberg?
what two types of elements bind together to form ionic bonds?
metals and non metals
what is the electron config for p
1s22s22p63s23p3 ↑↑↑
what ion has 14 protons and 18 electrons?
Si4-
If Li loses an electron then why is it written Li1+?
The charge went up by one because it lost an electron.
Heisenberg said we cannot know the trajectory of an electron.. what is trajectory?
the curve described by the orbit, or the pathway of the electron
what is nomenclature? --which do we name first in a ionic compound: the cation or anion or neither?
it is a collection of rules for naming things. cation.
write the electron config of Ca
how many maximum electrons are in each orbitals of the subshells s, p, d & f?
1s22s22p63s23p64s2 ↑↓
2, 6, 10, 14
give the atomic number, protons, electrons, group #, valence electrons for
neon and oxygen
also, is it a cation or anion?
neon: 10,10,10,18/8A,8, neutral
oxygen:8,8,8,16/6A,6, anion
What charge will H form when it becomes an ion?
provide: Cation/anion and charge.
+1, Cation, will lose it's only electron and become a floating proton.
______ introduced shells and orbitals that depend on energy levels.
Who is Niels Bohr?
define anion and cation. which ion is the cation, which ion is the anion?
cation: positively charged ion
anion: negatively charged ion
metals are cation, non metals are anion
what is the electron configuration for Vanadium atomic #23
what is the maximum capacity of orbitals for subshells s, p, d, and f?
1s22s22p63s23p64s23d3 ↑↑↑
(there NEEDs to be lines under arrows for orbitals, but it wouldn't let me do it)
1,3,5 & 7
write the formula for this ionic compound:
Cadmium (II) Nitrate
Cd (NO3)2
Electrons in the inner shell have_______(more/less) energy, whereas electrons in the outer shell have ________(more/less) energy.
1. Less
2. More
DAILY DOUBLE:
who was Frederick Soddy and Robert Millikan
(we had no more atomic thinkers sooo why not)
1. He proved the existence of isotopes of certain radioactive elements.
2.He is credited with the discovery of the specific charge and mass of an electron through the oil drop experiment.
What is variable charge?
when most transition metals (sometimes main group metals - those right of group 12 but left of the metalloids, known as the post-transition metals) form two or more cations with different charges
what electron has this configuration:
1s22s22p2
Carbon
name the ionic compound:
KCN
potassium cyanide
What Group/column are Alkali earth metals in?
None of them. AlkALI earth metals DON'T EXIST. AlkaLINE earth metals do.
What did Schrodinger contribute?
BONUS (+50): what model did he create?
He improved Bohr's model suggesting that the shells/orbitals are not spheres. Also came up with the math equation to approximate where electrons are shells.
BONUS: electron cloud.
what is the difference between an ionic compound and a binary compound?
a ionic compound is a compound that contains ions and is held together by ionic bond whereas a binary compound is a compound that just consists of 2 elements. One compound can be both, only one of these or neither.
what ion has this electron configuration?
1s22s22p63s23p64s23d34p65s24d6
There are many answers! Since this is a transition metal, there are atoms with variable charge that may or may not has this configuration
name ionic compound:
Fe(C2H3O2)3
Iron (III) acetate
