Use this chemistry calculator to reproduce a named relationship with explicit quantities and units for study, laboratory planning, or an independent numerical check.

e_g electrons

Number of electrons in the two degenerate e_g orbitals (0 through 4).

Check whether an octahedral complex has uneven e_g occupancy and therefore a strong Jahn-Teller distortion; t2g-only weak distortions are outside this check. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Strong distortion expected

Whether uneven e_g occupancy predicts a strong distortion.

• Bond, orbital, and structure rules are simplified representations. Resonance, relativistic effects, electron correlation, molecular geometry, oxidation state, and the measurement or computational method affect tabulated and predicted values.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check units and significant figures, compare the result with limiting cases, and use measured or source-specific constants where available. Laboratory, safety, and regulatory decisions require validated methods and appropriate uncertainty analysis.

• Bromothymol Blue Range Checker

  Check whether a pH falls within bromothymol blue range 6.0-7.6.

• Buffer Effective Checker

  Check whether a pH lies within the effective buffering range of pKa ± 1.

• Buffer pH After Addition

  Compute the buffer pH after adding strong base as pKa plus log10 of conjugate base over remaining weak acid.
