Answer

Brief Explanations:

  1. Like - charged particles repel. Protons are positively charged, so a proton repels another proton.
  2. Atoms with 7 valence electrons tend to gain 1 electron to achieve a stable octet. Non - metals often have 5 - 7 valence electrons and are semiconductors in some cases.
  3. When current flows through a conductor coiled around an iron bar, it creates a magnetic field, forming an electromagnet.
  4. In the United States, typical household appliances like a television or toaster use 120V.

Answer:

  1. b. proton
  2. d. semiconductor
  3. c. electromagnet
  4. b. 120V
