The nitrate ion (NO3-) has a trigonal planar molecular shape, with a symmetrical arrangement of the three oxygen atoms around the central nitrogen atom. This shape is due to the three electron pairs surrounding the nitrogen atom repelling each other to maximize the distance between them.
The molecular formula of lead(II) nitrate is Pb(NO3)2, and the molecular formula of sodium nitrate is NaNO3. Lead(II) nitrate contains one lead atom, two nitrate ions (NO3-), while sodium nitrate contains one sodium atom and one nitrate ion.
The molecular formula of zinc nitrate is Zn(NO3)2, which indicates that each formula unit contains one zinc ion (Zn) and two nitrate ions (NO3).
Some examples of molecular ions include ammonium ion (NH4+), hydroxide ion (OH-), nitrate ion (NO3-), and carbonate ion (CO32-). These ions are formed when a molecule gains or loses one or more electrons, resulting in a charged species.
The ion name for NO3 is nitrate.
The molecular shape of OSbCl3 when antimony (Sb) is the central atom is trigonal bipyramidal. This shape consists of three equatorial chlorine atoms and one axial oxygen atom, with bond angles of 90 degrees and 120 degrees.
