  • Primary difference between ionic and covalent bonds

    Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.
  • Atomic number of an element with 11 protons

    The atomic number is 11, which equals the number of protons in the element.
  • Mass number of an element with 11 protons and 12 neutrons

    The mass number is 23, calculated as protons (11) plus neutrons (12).
  • Why do noble gases rarely form chemical bonds?

    Noble gases have a full valence electron shell, making them chemically stable and unlikely to form bonds.
  • Balanced chemical equation for hydrogen and oxygen forming water

    The balanced equation is \(2H_2 + O_2 \rightarrow 2H_2O\).
  • pH indication of a substance turning pH strip bright red at pH 2

    A pH of 2 indicates the substance is an acid.
