What model is used to describe atomic structure in relation to the solar system?
The
Bohr model
View source
How can we visualize electrons in an atom according to the Bohr model?
As particles restricted to traveling particular distances from the
nucleus
View source
What is each restricted path that an electron can follow called?
A
shell
View source
What do shells represent in atomic structure?
The allowed energy levels of
electrons
in a restricted path
View source
Which shell has the lowest energy?
The
first
shell
View source
How does the energy of electrons change as they move further from the nucleus?
The energies
increase
as electrons
get
further
away
View source
What are the subdivisions of shells called?
Subshells
View source
Which shell is not subdivided into subshells?
The
first
shell
View source
How many subshells does the second shell have?
Two
subshells:
s and p
View source
How many subshells does the third shell have?
Three subshells:
s, p, and d
View source
How many subshells does the fourth shell have?
Four subshells:
s, p, d, and f
View source
What are atomic orbitals?
Regions in space where we are likely to find
electrons
View source
How many electrons can each orbital contain?
Two
electrons
View source
What must be true about the spins of the two electrons in an orbital?
They must have
opposite
spins
View source
What is the maximum number of electrons in the s subshell?
2
electrons
View source
How many orbitals are in the p subshell?
3
orbitals
View source
What is the maximum number of electrons in the p subshell?
6
electrons
View source
How many orbitals are in the d subshell?
5
orbitals
View source
What is the maximum number of electrons in the d subshell?
10
electrons
View source
What is the maximum number of electrons in the f subshell?
14
electrons
View source
How many orbitals are in the f subshell?
7
orbitals
View source
What does the Pauli exclusion principle state?
An orbital can hold a maximum of two electrons with
opposite
spins
View source
What is the significance of equivalent orbitals in a subshell?
They are grouped into subshells and have the same
energy
View source
How does the energy of orbitals change with distance from the nucleus?
Low-energy orbitals are
closer
to
the
nucleus
, and higher-energy orbitals are
further away
View source
What principle describes the sequential filling of atomic orbitals?
The
Aufbau principle
View source
What does the Aufbau principle state about filling orbitals?
Low-
energy
orbitals are filled first before higher-energy orbitals
View source
What is an atom's electronic configuration?
The distribution of an atom's
electrons
within its
orbitals
View source
How is the number of electrons in each subshell indicated in electronic configurations?
By a
superscript
number to the right of the subshell
View source
What is meant by degenerate orbitals?
Orbitals in a
subshell
that have the same
energy
View source
What does Hund's rule state about filling degenerate orbitals?
Each degenerate orbital must be occupied by one
electron
before any orbital is completely filled
View source
What is the electronic configuration of calcium, which has an atomic number of 20?
1s2 2s2 2p6 3s2 3p6
4s2
View source
Which subshell has the lowest energy in the order of relative energy?
s
subshell
View source
What is the electron configuration of bromine, Br?
[Ar]
4s23d104p5
View source
What is the valence shell of an atom?
The shell that holds the electrons located furthest from the
nucleus
View source
What are valence electrons?
Electrons located in the
valence shell
View source
What are core electrons?
Electrons located in
shells
closer to the
nucleus
View source
What role do valence electrons play in chemical reactions?
They
move
between
atoms
during
chemical reactions
View source
How does the reactivity of an atom depend on its valence electrons?
It depends on how readily its valence electrons will interact with
neighboring
atoms
View source
What happens if an atom's valence electrons are reluctant to interact with neighboring atoms?
No
chemical reaction
will occur
View source
What dictates the chemical properties of different elements?
Valence electrons
