Mass spectrometry is used to measure the relative masses of charged particles.

An atom becomes a positively charged ion when it loses an electron.

The process separates different masses and then measures them.

A technique used to measure the relative masses of charged particles.

Atoms that have gained or lost electrons, resulting in a net positive or negative charge.

Neutral atoms or molecules that have lost one or more electrons, resulting in a positive charge.

Neutral atoms or molecules that have gained one or more electrons, resulting in a negative charge.

Mass spectrometry is a technique used to measure the relative masses of different particles
Charged particles are affected by electric and magnetic fields
Charged particles are created from atoms in matter, either by losing or gaining electrons
Atoms can have excess positive or negative charges
Ions are formed when an atom loses or gains electrons
The experiments using charged particles in electric and magnetic fields were conducted in the early days of scientists studying atoms
The technique separates charged particles with different masses
Relative masses of particles are measured indirectly
The instrument (mass spectrometer) can also measure relative charges
All substances contain atoms in one form or another
Atoms contain protons and electrons with positive and negative charges, respectively
