. Write the electron configuration of an atom or ion. woflot a iorege
2. Draw the orbital diagram of an atom or ion.
3. Tell whether an atom or ion is pàramagnetic or diamagnetic.
A. True or False
1.
- The electron configuration of an atom could give the total number of electrons in
the atom.
2.
For a cation (an ion a with positive charge), the total number of electrons is greater
than its neutral atom.
3.
The CI ion has a total of 18 e-.
4.
The d subshell has 7 orbitals.
5.
If an atom or ion has unpaired electrons, it is said to be diamagnetic.
6.
Paramagnetic atoms are attracted to magnetic fields.
7.
According to the quantum mechanical model of the atom, electrons in the atom
could occupy any orbital.
Pauli's exclusion principle allows the occupation of any orbital by more than two
8.
electrons with similar or opposite spins.
By the Aufbau principle, electrons occupy the orbitals one at a time in order of
9.
increasing energy.
Hund's rule dictates that electrons in singly occupied orbitals within a subshell
10.
would have the same spin.
