Question

drag the right word to its definition
a particle of matter that
has a negative electrical

electron
neutron
proton

Explanation:

To solve this, we recall the definitions of subatomic particles:

• Electron: Has a negative charge and orbits the nucleus.
• Neutron: Neutral charge, in the nucleus.
• Proton: Positive charge, in the nucleus.

The given definition matches the electron.

Answer:

The word that matches the definition "a particle of matter that has a negative electrical charge and travels around the nucleus of an atom" is electron. So we drag "electron" to the definition.
