Define Relative Atomic Mass

The weighted mean mass of an atom of an element compared to 1/12 of the mass of Carbon-12 atom which has a mass of 12.

Define Relative Isotopic Mass

The mass of an isotope of an element compared to 1/12 of the mass of a Carbon-12 atom which has a mass of 12.

Define Relative Molecular Mass

The weighed mean mass of a molecule of an element compared with 1/12 of the mass of Carbon-12 which has a mass of 12.

What are the uses of a Mass Spectrometer

A Mass Spectrometer is used to determine the relative isotopic mass and relative abundance of isotopes.

What are the steps of Mass Spectrometry ?

The steps of Mass Spectrometry include sample ionization, ion acceleration, ion deflection through a magnetic or electric field, and detection of the ions to produce a mass spectrum.

What occurs during Sample Ionization ?

Sample ionization is the process where molecules are converted into ions, through electron bombardment, allowing them to be manipulated and analyzed in the mass spectrometer.

X(g) + e- → X+(g) 2e-

What occurs during Acceleration ?

Ions are sped up by passing through an electric field. Lower mass and high charge ions move faster.

What occurs during Deflection ?

A magnetic field is applied onto ions which pass through it. Lower mass and higher charge will have a greater deflection.

What occurs during Detection ?

Deflected ions pass through a narrow slit and are collected on a metallic plate connected to an amplifier and a mass spectrum is generated on a screen.

Formula for Relative Atomic Mass?

Abundance of the target Isotope / Combined Abundance of All Isotopes x 100
