Based on the image, what is the trend for Atomic Radii?
Increases up and to the left
Decreases up and to the left
Decreases down and to the left
Increases down and to the left
Other than organization, what can the periods tell you about atomic structure?
the number of valence electrons
the number of orbitals
the number of protons
the number of rows
The charge of an electron is
Positive
Neutral
Negative
The charge of a proton is
Positive
Neutral
Negative
The charge of a neutron is
Positive
Neutral
Negative
Which of the following shows valence electrons?
The number of protons...
determines the atomic mass
determines the atomic number
determines the number of neutrons
The number of neutrons...
is the atomic number
is found by subtracting from the atomic number
is found by subtracting from the atomic mass
is the atomic mass
The group with a full valence shell with almost no reactions

Why are these trends opposite?
bigger radius means farther from proton pull
bigger radius means more proton pull
smaller radius means fewer protons to pull
smaller radius means no pull needed
Ionization energy is...
A measure of the ability of an atom in a chemical compound to attract electrons from another atom in the compound
The measure from nucleus to edge of last filled orbital
The number of electrons an element can gain or lose
The energy required to remove one electron from a neutral atom of an element
Anions are
atoms of an element that has gained at least one electron; more electrons than protons
atoms of an element that has the same number of electrons and protons
atoms of an element that has lost at least one electron; more protons than electrons
atoms that have different numbers of neutrons
Cations are
atoms of an element that has gained at least one electron; more electrons than protons
atoms of an element that has the same number of electrons and protons
atoms of an element that has lost at least one electron; more protons than electrons
atoms that have different numbers of neutrons
Neutral atoms are
atoms of an element that has gained at least one electron; more electrons than protons
atoms of an element that has the same number of electrons and protons
atoms of an element that has lost at least one electron; more protons than electrons
atoms that have different numbers of neutrons
Isotopes are
atoms of an element that has gained at least one electron; more electrons than protons
atoms of an element that has the same number of electrons and protons
atoms of an element that has lost at least one electron; more protons than electrons
atoms that have different numbers of neutrons
Elements in the same group have similar behaviors because
they have the same number of periods
they have the same number of neutrons
they have the same number of protons
they have the same number of valence electrons
