Question
Please answer 4-10. No need for explanation, I just need an answer and analyze it by myself.
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.
8.
Pauli's exclusion principle allows the occupation of any orbital by more than two
electrons with similar or opposite spins.
9.
By the Aufbau principle, electrons occupy the orbitals one at a time in order of
increasing energy.
10.
Hund's rule dictates that electrons in singly occupied orbitals within a subshell
would have the same spin.
