Calculators

Calculates the molar mass (molecular weight) of a chemical compound or element. Enter the chemical formula to calculate its molar mass.

Calculates the type of chemical bond formed between two atoms based on the difference in their electronegativity values.

Calculates the effective nuclear charge (Zeff) experienced by an electron in an atom, taking into account the shielding effect of other electrons.

Calculates the bond order of a molecule based on the number of bonding and antibonding electrons or from the number of bonds between two atoms.

Calculates the average atomic mass of an element based on the masses and natural abundances of its isotopes.

Calculates the atomic mass of an atom based on the number of protons and neutrons, displaying the result in atomic mass units (amu)

Calculates the number of protons, neutrons, and electrons in an atom based on its atomic number and mass number. Assumes a neutral atom unless the charge is specified.
