Atoms and electric charge

What is the definition of electric charge?

• a physical property causing objects or atoms to attract or repel each other without touching

• a physical property causing objects or atoms to be solid, liquid, or gas

• a physical property causing objects or atoms to be electrocuted

• a physical property causing objects or atoms to move magnetically

If an atom has more protons than electrons, it will be:

• Positively charged

• Negatively charged

• Neutrally charged

• Positively charged

• Negatively charged

• Neutrally charged

If an atom has less electrons than protons, it will be:

• Positively charged

• Negatively charged

• Neutrally charged

If an atom is neutral and then it loses electrons, it will be:

• Negatively charged

• Positively charged

• Neutrally charged

If an atom is neutral and then it gains electrons, it will be:

• Positively charged

• Negatively charged

• Neutrally charged
