Anything that has mass and occupies space.
What is matter?
A positively charged subatomic particle.
What is a proton?
The pattern formed when light emitted by an element is separated into the different wavelengths it contains.
Names of the two models we have used to represent atoms.
What is Bohr Model and Quantum Mechanical Model?
List the number of electrons each subshell can hold.
What is:
s - 2p - 6
d - 10
f - 14
The simplest form of matter that has a characteristic set of properties.
What is an element?
Same as the number of protons in an element. Also how we find an element on the periodic table.
What is the atomic number?
Place(s) where we find electrons outside of the nucleus.
Names of each principle subshell.
What is s, p, d and f?
The address of an element.
What is electron configuration?
What is one element?
What is the mass number?
We find less energy in this location.
What is the ground state?
Each subshell contains a certain number of these.
What is atomic orbitals?
Electrons in the outermost energy shell.
What are valence electrons?
Put the following molecules in increasing order:
Cl3H1 Br10 F4Sr3 O6
What is Cl3H1 O6 F4Sr3 Br10?
The amount each isotope of an element appears in nature.
We will find the longest or biggest wavelengths at this location.
What is the ground state?
1. What is the formula used to calculate the number of electrons that fit on each energy level?
2. What is the maximum number of electrons the 7th energy level could hold?
1. What is 2n2?
2. What is 98 electrons?
Write the full and noble gas electron configuration for Cd.
Full configuration:
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10
Noble gas shortcut:
[Kr]4d105s2
1. List the 3 states of matter.
2. Which state has the most kinetic energy? Why?
What is solid, liquid and gas?
A gas has the most kinetic energy because the particles are not tightly packed.
Given the following, how could we approximate the atomic mass of Nickel?
58Ni 68.0769%
60Ni 26.2231%
61Ni 1.1399%
62Ni 3.6345%
64Ni 0.9256%
The atomic mass for Nickel would be closest to the isotope with the greatest percent abundance, which is 58Ni.
This transition between energy levels will release energy.
What is moving from an excited state toward the ground state?
List the first 8 subshells in order of increasing energy.
What is 1s 2s 2p 3s 3p 4s 3d 4p?
1. Draw the Bohr Model for Cd.
2. Draw the Electron Dot Structure for Cd.
3. Which group is Cd in and how many valence electrons does that group have?
