A O-18 has 2 more neutrons than O-16
<h3>Further explanation</h3>Oxygen is located in group 16 in the p block which has the atomic number 8
In the atomic symbol (neutral), the atomic number indicates the number of electrons and protons. while the number of neutrons is obtained from the difference between the mass number and the atomic number.
The isotope will have the same number of protons (atomic number) but a different mass number
Isotopes of oxygen include: O-18 and O-16
Propane has a molecular formula C3H8.
It is of the form CnH2n+2.
where n = number of C atoms. In present case n = 3.
Each carbon atom in propane is sp3 hydribized. Thus, there are 4 hydrid orbital associated with each carbon atom
The central C atom is sigma bonded to two other carbon atoms and two hydrogen atoms.
Such, sp3 hydridized orbitals are spacial orientated at an angle of
, in order to minimize repulsion between the electrons.
Hence, the c—c—c bond angle in propane, c3h8, is closest to
