What is the Atomic Number
and the amount of Neutrons in the
following Atom?
Atomic Number = 36
Neutrons = 48
What is ionization energy?
The amount of energy needed to
remove an electron from an atom
Red Light has a ____ wavelength
and a _____ frequency compared
to Violet light
Long Wavelength
Low Frequency
Does Bromine Gain or lose
electrons? Is it a metal, nonmetal, or
metalloid?
Gains electrons and
becomes negative in charge
Nonmetal
This “effect” causes atoms on the
bottom of the periodic Table to
have a small ionization energy
What is the shielding effect?
The model of “atomos” was used by
which scientist(s)
Who was Democritus and
Dalton?
nd
2
The
law of this scientist was
changed with the discovery of
subatomic particles
ie. Protons, neutrons, and electrons
Who was Dalton?
Which scientist had an atomic
model with a positive Nucleus
and a Negative electron cloud
making up the majority of their
space
Who was Rutherford?
Hydrogen was electrified to
observe electrons jumping energy
levels
Who was Niels Bohr?
Draw and label Thomson’s
model of the Atom
The plum pudding model
A positively charged ball with
negatively charged electrons
This family has two valence
electrons.
What are the Alkaline Earth Metals?
Silicon shares, rather than loses
or gains, electrons.
What is a Metalloid?
This family is the entire d Block
What are the Transition Metals
This family has valence electrons
that are s2p5
What are the Halogens?
This is a family of nonreactive
gasses
What are the noble gasses?
The plateau during the heating of a
solid pure substance represents…
The Melting Point
The point at which both solids and
liquids are found
A gas evolves with a strong odor
from two chemicals being mixed.
There is a lot of heat produced
What is an exothermic chemical
change
These letters represent the heating of
the solid
What is A-B
Calculate the Atomic Mass of
Copper Given the following info.
Cu 63.0 has an abundance of 69.2%
Cu 65.0 has an abundance of 30.8%
Sig Figs and Units!!!!!
Copper’s Atomic Mass
63.6 amu
You need to include amu to be correct!!
Sig Figs!!!!
What does mass measure?
The amount of
matter in a
substance
What truly determines if an atom is a
metal?
Low ionization energy and a large
atomic radius
The Lewis Dot Structure for
Aluminum
.
.Al.
What is the Electron Configuration
and
Lewis Dot Structure for
Tin
Use both long hand and nobel gas
configuration
Sn: 1s22s22p63s23p64s23d104p65s24d105p2
Sn: [Kr] 5s24d105p2
Why don’t we draw a Bohr model
for Titanium?
Titanium is in the d-block. Bohr
models stop at Ca. The 3d
electrons go back to the third
energy level rather than
continuing on the 4th energy
level
If You remove an electron from
Potassium, how many Valence
electrons does it have?
Why would potassium lose an
electron?
Eight
Potassium lost one valence to have
the same electron configuration as
Argon, thus having eight electrons.
