The parent isotope is cobalt-59 (see the picture below).
The mass number is 59 and atomic number is 27 of the parent isotope.
Neutron activation is the process in which atomic nucleus capture free neutron or neutrons.
Cobalt-60 is produced in nuclear reactors in process of neutron activation from parent isotope cobalt-59 (see the picture below).
Atomic number (Z) is total number of protons and mass number (A) is total number of protons and neutrons in a nucleus.
Cobalt-59 and cobalt-60 are the isotopes of chemical element cobalt.
Isotopes are chemical elements with same atomic number (Z), but different mass number (different number of neutrons).

Answer:
Both ethanol and diethyl ether have tetrahedral geometry.
Explanation:
VSEPR Rules are
1. Identify the central atom.
2. Count its valence electrons.
3. Add one electron for each bonding atom.
4. Add or subtract electrons for charge
5. Divide the total of these by 2 to find the total.
number of electron pairs.
6. Use this number to predict the shape.
The attachment shows their Lewis's dot structure.
