How does the electron-cloud model describe electrons?
the exact position of an electron can be known.
an electron can be found at certain distances from the nucleus.
an electron has a high probability of being in certain regions.
each electron follows a specific path around the nucleus.

An electron has a high probability of being in certain regions.

Explanation: According to electron cloud model given by Schrodinger, the electrons do not revolve in fixed paths as said by Bohr but can be found anywhere in the atom.

There are regions where the probability of finding the electron is maximum which are called as orbitals.

Orbital is defined as the region within an atom that encloses where the electron is likely to be 90% of the time.

c) up is the direction the magnetic force is acting on the charge.
