Question

drag the right word to its definition
a particle of matter that
has a positive electrical
charge and forms part of
the nucleus of an atom.
proton
electron
neutron

Explanation:

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

• A proton is a subatomic particle with a positive electrical charge and is part of the atom's nucleus.
• An electron has a negative charge and orbits the nucleus.
• A neutron has no charge and is also in the nucleus. So the particle matching the given definition is the proton.

Answer:

The word that matches the definition "a particle of matter that has a positive electrical charge and forms part of the nucleus of an atom" is "proton". So we drag "proton" to the definition.
