Question

lets learn about chemical reactions. in chemistry, atoms are the smallest unit of matter. label the parts of the atom by dragging the labels onto the blank boxes. nucleus neutron electron proton these particles have a positive electrical charge. drop here these particles have no electrical charge. drop here the positive and neutral particles of the atom are held together in the center of the atom. drop here these particles have a negative electrical charge. drop here

Explanation:

Step1: Identify positive charge particle

Protons have a positive electrical charge. So the box with "These particles have a positive electrical charge" should be labeled with "Proton".

Step2: Identify negative charge particle

Electrons have a negative electrical charge. So the box with "These particles have a negative electrical charge" should be labeled with "Electron".

Step3: Identify neutral charge particle

Neutrons have no electrical charge (neutral). So the box with "These particles have no electrical charge" should be labeled with "Neutron".

Step4: Identify the center of the atom

The nucleus is the center of the atom where protons and neutrons (positive and neutral particles) are held together. So the box with "The positive and neutral particles of the atom are held together in the center of the atom" should be labeled with "Nucleus".

Step5: Match the labels to the positions (visual check)

• "These particles have a positive electrical charge" → Proton (rightmost box with positive charge description)
• "These particles have a negative electrical charge" → Electron (leftmost box with negative charge description)
• "These particles have no electrical charge" → Neutron (second from right box with no charge description)
• "The positive and neutral particles of the atom are held together in the center of the atom" → Nucleus (second from left box with nucleus description)
• The visual of the atom: the central cluster is the nucleus (containing protons and neutrons), and the small dots around are electrons. So the labels match the descriptions based on atomic structure knowledge.

Answer:

• "These particles have a positive electrical charge" → Proton
• "These particles have a negative electrical charge" → Electron
• "These particles have no electrical charge" → Neutron
• "The positive and neutral particles of the atom are held together in the center of the atom" → Nucleus
