The structural formula for sodium nitrite is NaNO2. It consists of one sodium (Na) atom, one nitrogen (N) atom, and two oxygen (O) atoms.
The structural formula of chlorous acid is HClO2. It consists of one hydrogen atom, one chlorine atom, and two oxygen atoms bonded together.
The structural formula of methanal (formaldehyde) is HCHO, where a carbon atom is double bonded to an oxygen atom and single bonded to two hydrogen atoms.
The formula to calculate the effective nuclear charge on a valence electron in an oxygen atom is Zeff Z - S, where Z is the atomic number of the element (in this case, oxygen with an atomic number of 8) and S is the shielding constant.
The structural formula of sodium carbonate is Na2CO3, indicating that it consists of two sodium atoms, one carbon atom, and three oxygen atoms.
The structural formula of a phosphate radical is PO₄³⁻. It consists of one phosphorus atom bonded to four oxygen atoms, with a net charge of -3.
The full structural formula for CH3-OH is CH3-OH, which represents a molecule of methanol. It consists of one carbon atom bonded to three hydrogen atoms and one oxygen atom through a single covalent bond.
Nitrogen trichloride has NCl3 as its chemical formula. Its structural formula is the same, as it presents no "mysterious" geometry. The central nitrogen atom is bonded to the three separate chlorine atoms to form the molecule. Use the link below to see a diagram of the molecule and learn more about its chemistry.
A molecule of carbon dioxide has the formula CO2, which means that there are one carbon atom and two oxygen atoms in each molecule. Each oxygen atom forms a double bond with the central carbon atom. Its structural formula is O=C=O, and the molecule is linear.
The structural formula for hydrochloric acid (HCl) is H-Cl, where a hydrogen atom is attached to a chlorine atom by a single covalent bond.
an oxygen ion has gained electrons, increasing the electron-electron repulsion and making the electron cloud expand. This causes the ion to be larger than the neutral atom.
The structural formula of diethyl ether is (C_4H_{10}O). It consists of two ethyl groups (-C2H5) attached to an oxygen atom in the middle.
