Oxygen dichloride molecule consists of an oxygen atom and two chlorine atoms. According to the VSEPR theory, the 3-D shape of the compound is bent.
There are 6 valence electrons in the oxygen atom and each chlorine atom has 1 valence electrons. Therefore, there are 8 valence electrons or 4 pairs of valence electrons.
According to VSEPR theory, due repulsion between 4 pairs of valence electrons, bond angle between two O-Cl bonds becomes 110 degrees and the shape of the molecule of the compound becomes bent.
78 and 78. An atom of the element has 78 electrons and 78 protons.
The atomic number is 78, so the atom has 78 protons (+).
If the atom is neutral, it must contain 78 electrons (-).
